JP7615645B2 - Integrated control system for virtual power plant and integrated control method thereof - Google Patents

Description

The present invention relates to an integrated control system for a virtual power plant and an integrated control method thereof.

In recent years, in order to realize a more stable and less wasteful power system, development has been progressing on virtual power plants (VPPs) that integrate and control various energy resources owned by consumers, such as distributed power sources and power storage facilities, and function as if they were a single power plant (see Patent Document 1).
By forming a virtual power plant, it becomes possible to adjust the balance of supply and demand for electricity through demand response such as up-demand response (DR) and down-demand response (DR), instead of adjusting the output of large-scale power plants such as thermal power plants as has been done in the past.

JP 2020-108301 A

Comparing the formation of a virtual power plant in an urban area with the formation of a virtual power plant in a surrounding area surrounding the urban area, urban areas are often able to form a virtual power plant efficiently because they are rich in various types of energy resources such as power generation facilities and storage facilities, whereas surrounding areas are often biased toward certain types of energy resources (such as solar power generation facilities), making it difficult to form a virtual power plant.
As a result, the current situation is that energy resources available in the surrounding area are not being effectively utilized as targets for virtual power plants.

The present invention aims to provide an integrated control system and an integrated control method for a virtual power plant that efficiently utilizes various energy resources that are ubiquitous, regardless of whether they are in an urban area or a surrounding area, to form a virtual power plant and ensure a better balance between the supply and demand of electricity.

The present invention, which is a main aspect of the present invention for solving the above-mentioned problems, is an integrated control system for a virtual power plant that integrates and controls a plurality of energy resources owned by a plurality of consumers and distributed in various locations via a network, and functions as if they were a single power plant, the system including an attribute storage unit that stores attribute information including information indicating the power usage status of the plurality of consumers, information indicating the power system to which the plurality of energy resources are connected, and information indicating the geographical positions of the plurality of energy resources , and a control unit that selectively integrates energy resources from among the plurality of energy resources based on the attribute information to form a virtual power plant, and controls the virtual power plant in response to demand response. and a second integrated control unit that integrates the reserve energy resources that are not integrated into the virtual power plant into the virtual power plant so that the virtual power plant can respond to the demand response when the virtual power plant is no longer able to respond to the scale of supply and demand adjustment of the demand response , wherein the first integrated control unit selectively integrates the energy resources to form the virtual power plant, giving priority to information indicating the power usage status of the multiple consumers and information of the power grid to which the multiple energy resources are connected, over information indicating the geographical locations of the multiple energy resources, among the attribute information .
Other features of the present invention will become apparent from the accompanying drawings and the description of this specification.

According to the present invention, it is possible to create a virtual power plant by efficiently utilizing various energy resources that are ubiquitous, regardless of whether they are in an urban area or a surrounding area, and to more reliably balance the supply and demand of electricity.

The present specification and accompanying drawings make clear at least the following:

FIG. 1 is an overall diagram for explaining the formation of a virtual power plant according to the present embodiment. The virtual power plant is operated by an aggregator. In this embodiment, the aggregator is a general term for a resource aggregator and an aggregation coordinator, and may refer to either the resource aggregator or the aggregation coordinator, or both. The resource aggregator controls the energy resources based on a contract with each consumer who owns the energy resources. The aggregation coordinator aggregates the amount of power controlled by each resource aggregator, and trades power with a general power transmission and distribution business operator and a retail electricity business operator. In this embodiment, the general power transmission and distribution business operator and the retail electricity business operator are collectively referred to as an electricity business operator. Therefore, the electricity business operator may refer to either the general power transmission and distribution business operator and the retail electricity business operator, or both.
In this embodiment, for example, it is assumed that a management area 10 in which a virtual power plant is to be formed is determined by an aggregator. A plurality of energy resources owned by a plurality of consumers, such as energy generation, energy storage, and energy saving resources, are distributed and installed in this management area 10. The scale of the management area 10 may be a relatively small one such as a city, ward, town, or village, or a relatively large one spanning prefectures.

The management area 10 is roughly divided into, for example, an urban area 10A and a surrounding area 10B surrounding the urban area 10A. The urban area 10A tends to be densely populated with commercial facilities and industrial facilities for economic activities, and many energy resources 20 are installed in a concentrated manner. On the other hand, the surrounding area 10B tends to have more residential buildings than facilities for economic activities, and fewer energy resources 20 are installed there than in the urban area 10A. Note that the multiple energy resources distributed in the urban area 10A are referred to as 20A, and the multiple energy resources distributed in the surrounding area 10B are referred to as 20B. These energy resources 20A and 20B are connected to a power grid, but are selectively integrated to be able to communicate via a network 30 such as IoT according to instructions from an aggregator server 50 described later.

The virtual power plant is formed by integrating, via a network 30, the energy resources 20A, 20B (e.g., within the bold frame marked VPP in FIG. 1) that correspond to predetermined attributes for multiple consumers and the energy resources 20A, 20B from among the energy resources 20A, 20B in the management area 10, regardless of whether it is an urban area 10A or a surrounding area 10B. The virtual power plant formed in this way operates to intentionally increase or decrease the amount of electricity demanded in response to demand responses such as up DR and down DR that occur according to the amount of electricity supplied at that time, so as to contribute to balancing the amount of electricity demanded by consumers with the amount of electricity supplied. In other words, the virtual power plant functions as a virtual power plant.

The energy resources 20A and 20B are connected to a relay system 40 (also called a power management system) that relays communications between a GW (gateway), HEMS (Home Energy Management System), BEMS (Building Energy Management System), FEMS (Factory Energy Management System), etc., so that a virtual power plant can be formed through the network 30. Furthermore, the energy resources 20A and 20B are communicatively connected to an aggregator server 50 that integrates the energy resources 20A and 20B and thereby forms a virtual power plant, via the relay system 40 and the network 30.

Demand response is a demand response command for changing the power demand pattern by controlling the power demand of the multiple energy resources 20A and 20B forming the virtual power plant so that the power supply and the power demand by the consumer are balanced. There are two types of demand response: up DR and down DR. Up DR is a command for increasing the power demand (consumption) of the multiple energy resources 20A and 20B in the virtual power plant when the power demand is less than the power supply. For example, when there is a risk that the power supply of a solar power generation system connected to the power grid will be oversupplied due to the influence of fine weather, an up DR is generated. For example, when the energy resources 20A and 20B forming the virtual power plant include a storage battery (storage energy resource), the demand for the storage battery is increased to charge the storage battery with the amount of power that would be oversupplied. On the other hand, down DR is a command for decreasing the power demand of the multiple energy resources 20A and 20B in the virtual power plant when the power demand is greater than the power supply. For example, if there is a high demand for air conditioners and the like during a heatwave and there is a risk of a shortage in the supply of electricity, a down DR is generated to reduce the demand for one of the energy resources 20A, 20B in the virtual power plant. In this way, changing the demand pattern for multiple energy resources 20A, 20B in the virtual power plant can contribute to balancing the supply and demand of electricity.

The energy generating resource, which is one type of the energy resources 20A and 20B, is a resource that generates electricity, and examples thereof include a photovoltaic power generation system, a cogeneration system, a system that utilizes renewable energy heat (geothermal heat, solar heat, snow and ice heat, etc.), and a fuel cell vehicle. The energy storage resource, which is another type of the energy resources 20A and 20B, is a resource that stores electric energy, and examples thereof include a home storage battery, a system storage battery, and a heat pump water heater. The energy saving resource, which is another type of the energy resources 20A and 20B, is a resource that saves electricity, and examples thereof include a business/industrial EMS (Energy Management System), lighting equipment that has been converted to IoT, air conditioning equipment, and refrigeration equipment. The virtual power plant is formed by selectively integrating the energy generating resources, energy storage resources, and energy saving resources included in these multiple energy resources 20A and 20B based on the attributes of multiple consumers and the multiple energy resources 20A and 20B.

The aggregator server 50 is a server managed by an aggregator. As described above, aggregator is a general term for a resource aggregator and an aggregation coordinator, so there are servers managed by resource aggregators (also referred to as resource aggregator servers) and servers managed by aggregation coordinators (also referred to as aggregation coordinator servers). In this embodiment, the resource aggregator servers and aggregation coordinator servers are collectively referred to as aggregator servers 50. The aggregator server 50 is configured as hardware using a computer, and various functions as the aggregator server 50 are realized by software processing on the computer.

The electric utility server 60 is a server managed by an electric utility. As described above, electric utility refers collectively to general electricity transmission and distribution business operators and retail electricity business operators, and therefore includes a server managed by the general electricity transmission and distribution business operator (also referred to as the general electricity transmission and distribution business operator server) and a server managed by the retail electricity business operator (also referred to as the retail electricity business operator server). In this embodiment, the general electricity transmission and distribution business operator server and the retail electricity business operator server are collectively referred to as the electric utility server 60. The electric utility server 60 generates a demand response to the aggregator server 50, and receives a demand response result in which the operation of the energy resources 20A and 20B is controlled according to the demand response from the aggregator server 50. The electric utility server 60 is configured as hardware by a computer, and various functions as the electric utility server 60 are realized by software processing of the computer.

In this embodiment, the virtual power plant collectively refers to a first virtual power plant and a second virtual power plant that is larger in scale than the first virtual power plant. The first virtual power plant and the second virtual power plant are common in that both are composed of a plurality of energy resources 20A, 20B, but are different in that the first virtual power plant is formed by integrating a plurality of energy resources 20A, 20B that do not belong to any virtual power plant, whereas the second virtual power plant is formed by integrating a plurality of virtual power plants.
Furthermore, as will be described in detail later, if it becomes difficult to respond to a demand response while the demand response is being responded to, the scale of the virtual power plant is expanded to deal with the situation (hereinafter, the expanded virtual power plant is also referred to as VPP'). In this case, in addition to expanding the scale by integrating other virtual power plants, it is also possible to expand the scale by integrating energy resources 20A, 20B that do not belong to any virtual power plant.

The aggregator server 50 selectively integrates multiple energy resources 20A, 20B installed within the management area 10, regardless of whether it is an urban area 10A or a surrounding area 10B, via the network 30 based on multiple consumers who own the energy resources 20A, 20B and predetermined attributes of the multiple energy resources 20A, 20B, thereby forming a first virtual power plant.
Furthermore, for example, when there is a risk that the demand of a single first virtual power plant is insufficient to respond to a demand response, the aggregator server 50 selectively integrates multiple first virtual power plants in the management area 10 via the network 30 based on the attributes of multiple first virtual power plants that have already been formed, thereby forming a second virtual power plant that is larger in scale than the first virtual power plant.
Furthermore, if, for example, the ability of the energy resources 20A, 20B integrated into the second virtual power plant to adjust the demand is reduced due to deterioration over time, or if these energy resources 20A, 20B break down, causing the demand to be insufficient even though the second virtual power plant is in the middle of responding to the lowered DR, and the aggregator server 50 is unable to fully respond to the lowered DR, the aggregator server 50 expands the scale of the second virtual power plant by integrating other virtual power plants into the second virtual power plant, or by integrating spare energy resources 20A, 20B that are not integrated into any virtual power plant, so that the second virtual power plant can respond to the lowered DR.

FIG. 2 is a block diagram showing the functions of the aggregator server 50. As shown in FIG.
The aggregator server 50 has a first attribute storage unit 510 and a formation control unit 530 as means for forming a first virtual power plant, and has a second attribute storage unit 520 and a first integrated control unit 540 as means for forming a second virtual power plant, and further has a second integrated control unit 550 so that the virtual power plant can continue to respond to a demand response when the virtual power plant is unable to respond while responding to the demand response. The aggregator server 50 is configured as hardware by a computer similar to the electric utility server 60, and realizes the functions of the first and second attribute storage units 510, 520, the formation control unit 530, and the first and second integrated control units 540, 550 through software processing of the computer.

The first attribute storage unit 510 stores in advance attribute information that is the basis for the formation control unit 530 to selectively integrate the multiple energy resources 20A, 20B. For example, the attribute information includes, for the multiple energy resources 20A, 20B that are distributed and installed in the management area 10, first attribute information A indicating the power usage status of multiple consumers who own these energy resources 20A, 20B, first attribute information B indicating the power system to which the multiple energy resources 20A, 20B are connected, and first attribute information C indicating the geographical positions of the multiple energy resources 20A, 20B. The first attribute storage unit 510 is configured using hardware such as a hard disk or a semiconductor non-volatile memory, and is capable of functions such as referencing and updating the first attribute information A to C by software processing.

Figure 3A shows an example of table data of first attribute information A stored in the first attribute storage unit 510. Figure 3B shows an example of table data of first attribute information B stored in the first attribute storage unit 510. Figure 3C shows an example of table data of first attribute information C stored in the first attribute storage unit 510.

The first attribute information A is, for example, information that captures the power consumption (power consumption curve) for each predetermined time in one day of each of multiple consumers who own energy resources 20A and 20B as the power usage status. The predetermined time may be, for example, 15 minutes or one hour. In addition, this one day may be divided into, for example, weekdays and holidays and public holidays. In this case, the power consumption for each predetermined time on weekdays can be, for example, the average value of the power consumption from Monday to Friday for each predetermined time, while the power consumption for each predetermined time on public holidays and public holidays can be, for example, the average value of the power demand for Saturday, Sunday, and public holidays for each predetermined time. When the power consumption for each predetermined time in one day is divided into weekdays and holidays and public holidays, this information may be updated, for example, on a weekly basis and stored in the first attribute storage unit 510. This makes it possible to effectively use information indicating the latest power usage status of multiple consumers in forming the first virtual power plant. For example, let multiple consumers be X1 to Xn, and let information showing the power usage status of each consumer X1 to Xn on weekdays be W11 to W1n, and information showing the power usage status of each consumer X1 to Xn on weekends and holidays be W21 to W2n.

Figure 4 shows an example of a power system, and all areas shown in Figure 4 correspond to the management area 10. Figure 4 shows, for example, two substations H1 and H2, buses K1 and K2 connected to the substations H1 and H2, distribution lines F1 and F2 branching off from the bus K1, and distribution lines F3 and F4 branching off from the bus K2. For example, the distribution lines F1 and F2 are formed so as to span an urban area 10A, and multiple energy resources 20A (white circles) are installed in a dispersed and dense manner within this urban area 10A. Furthermore, the distribution lines F2 to F4 are formed so as to span a surrounding area 10B, and multiple energy resources 20B (white triangles) are installed in a dispersed manner within this surrounding area 10B without being dense.

The first attribute information B is, for example, information indicating the power distribution lines F1-F4 to which the multiple energy resources 20A, 20B are connected. For example, if the multiple energy resources distributed in the urban area 10A across the power distribution lines F1, F2 are 20A1-20An, the multiple energy resources 20A1-20An are associated with information on the power distribution lines F1, F2 to which they are connected and information indicating the consumers X1-Xn that own the corresponding energy resources 20A1-20An, and are stored in the first attribute storage unit 510 as the first attribute information B. Furthermore, assuming that the multiple energy resources distributed in the surrounding area 10B spanning the power distribution lines F2 to F4 are 20B1 to 20Bn, the multiple energy resources 20B1 to 20Bn are associated with information on the power distribution lines F2 to F4 to which they are connected and information indicating the consumers X1 to Xn who own the corresponding energy resources 20B1 to 20Bn, and are stored in the first attribute storage unit 510 as the first attribute information B. Here, the information indicating the consumers X1 to Xn may be the same information as the consumers X1 to Xn in the first attribute information A, or may be information corresponding to the consumers X1 to Xn in the first attribute information A. In other words, any information may be used as long as the information indicates the consumers X1 to Xn in the first attribute information A and B.

The first attribute information C is information indicating the geographical positions where the multiple energy resources 20A and 20B are installed in the urban area 10A and the surrounding area 10B, respectively. The multiple energy resources 20A1 to 20An distributed in the urban area 10A in FIG. 4 are associated with information indicating the geographical positions of the multiple energy resources 20A1 to 20An and information indicating the consumers X1 to Xn who own the corresponding multiple energy resources 20A1 to 20An, and are stored in the first attribute storage unit 510 as the first attribute information C. Similarly, the multiple energy resources 20B1 to 20Bn distributed in the surrounding area 10B in FIG. 4 are associated with information indicating the geographical positions of the multiple energy resources 20B1 to 20Bn and information indicating the consumers X1 to Xn who own the corresponding multiple energy resources 20B1 to 20Bn, and are stored in the first attribute storage unit 510 as the first attribute information C. Here, the information indicating the consumers X1 to Xn may be the same as the consumers X1 to Xn in the first attribute information A, or may be information corresponding to the consumers X1 to Xn in the first attribute information A. In other words, any information may be used as long as the consumers X1 to Xn in the first attribute information A and C match. In addition, the information indicating the geographical positions of the multiple energy resources 20A and 20B may be, for example, address information or longitude and latitude information indicating the installation positions of the corresponding energy resources 20A and 20B, but in this embodiment, it is address information. For example, the address information of the energy resources 20A1 to 20An is AD11 to AD1n, and the address information of the energy resources 20B1 to 20Bn is AD21 to AD2n.

The formation control unit 530 selectively integrates, via the network 30, the multiple energy resources 20A distributed within the urban area 10A and the multiple energy resources 20B distributed in the surrounding area 10B that are determined to be optimal when responding to a demand response by referring to the table data of the first attribute information A to C stored in the first attribute storage unit 510, to form a first virtual power plant.

The formation control unit 530 selectively integrates the multiple energy resources 20A and 20B by using the first attribute information A and B in preference to the first attribute information C.

Here, the first attribute information A includes information indicating the power consumption of each of the consumers X1 to Xn for each predetermined time in one day. Therefore, the formation control unit 530 selects the consumers X1 to Xn that consume similar power from the first attribute information A, and integrates the energy resources 20A and 20B owned by the selected consumers X1 to Xn via the network 30. As an example, when it is necessary to reduce the power demand from 12:00 to 15:00 on weekdays by a reduction DR, the formation control unit 530 selects only the information W11 to W1n indicating the power usage status in which the power consumption from 12:00 to 15:00 on weekdays is greater than a certain amount from the first attribute information A, and integrates the energy resources 20A and 20B owned by the consumers X1 to Xn that correspond to the information W11 to W1n indicating the selected power usage status via the network 30. In the first virtual power plant thus formed, it is possible to efficiently reduce the amount of power consumed by the energy resources 20A and 20B in accordance with the down DR between 12:00 and 15:00 on weekdays. In this way, the first attribute information A is useful information for predicting the demand for the energy resources 20A and 20B that constitute the first virtual power plant in response to demand response, and how that demand is to be controlled. In addition, since the consumers X1 to Xn selected from the first attribute information A have similar power usage conditions, the information has a high priority as information used for the first virtual power plant to operate efficiently in one demand response.

The first attribute information B is information indicating which of the power distribution lines F1 to F4 the multiple energy resources 20A and 20B are connected to. The power distribution lines F1 and F2 are power lines branching off from a common bus K1, so they are strongly correlated, and the distance between the power distribution lines F1 and F2 is relatively short compared to other power systems (e.g., power distribution lines F3 and F4). Similarly, the power distribution lines F3 and F4 are power lines branching off from a common bus K2, so they are strongly correlated, and the distance between the power distribution lines F3 and F4 is relatively short compared to other power systems (e.g., power distribution lines F1 and F2). For this reason, the multiple energy resources 20A and 20B connected to the power distribution lines F1 and F2 (or power distribution lines F3 and F4) are likely to be affected by the same natural environment (weather, disasters, etc.). The same can be said about the energy resources 20A and 20B that are commonly connected to any one of the power distribution lines F1 to F4. Therefore, the energy resources 20A and 20B connected to at least one of the power distribution lines F1 and F2 and at least one of the power distribution lines F3 and F4 are likely to have similar power usage conditions, and therefore have high priority as information used by the first virtual power plant to operate efficiently in one demand response.

The first attribute information C is information indicating the geographical positions of the multiple energy resources 20A, 20B, and depending on the demand response conditions, the energy resources 20A, 20B distributed in geographically close locations (e.g., the energy resources 20A, 20B connected to the distribution lines F1, F2) or the energy resources 20A, 20B distributed in geographically distant locations (e.g., the energy resources 20A, 20B connected to the distribution lines F1, F4) can be used as information for forming the first virtual power plant. In order to balance the amount of power demand consumed by consumers against the amount of power supply, the first virtual power plant is operated efficiently with a small number of demand responses in this embodiment, with the aim of balancing the amount of power demand consumed by consumers against the amount of power supply, and the first attribute information A, B is used preferentially over the first attribute information C.

In this embodiment, the first attribute information A to C is used, but the attribute information is not limited to this. In addition to the first attribute information A to C, for example, weather forecast information, event information, hazard information, etc. for the area in which the energy resources 20A, 20B are divided may be used as appropriate to integrate the multiple energy resources 20A, 20B.

The second attribute storage unit 520 stores in advance attribute information that is the basis for the first integration control unit 540 to select a plurality of first virtual power plants to be integrated as a second virtual power plant from among a plurality of first virtual power plants already formed by the formation control unit 530. The attribute information includes, for example, second attribute information D indicating the power usage status of each of the plurality of first virtual power plants formed in the management area 10, second attribute information E indicating the power system to which the plurality of first virtual power plants are connected, and second attribute information F indicating the geographical positions of the plurality of first virtual power plants. Note that, like the first attribute storage unit 510, the second attribute storage unit 520 is configured using hardware such as a hard disk or a semiconductor nonvolatile memory, and functions such as referencing and updating the second attribute information D to F are possible by software processing. Note that the first and second attribute storage units 510 and 520 may be configured to separate address spaces within the same hard disk or the same semiconductor nonvolatile memory.

Figure 3D shows an example of table data of second attribute information D stored in the second attribute storage unit 520. Figure 3E shows an example of table data of second attribute information E stored in the second attribute storage unit 520. Figure 3F shows an example of table data of second attribute information F stored in the second attribute storage unit 520. Note that the second attribute information D to F is generated by the first integrated control unit 540, for example, aggregating and editing the first attribute information A to C relating to all of the energy resources 20A, 20B forming each first virtual power plant after multiple first virtual power plants are formed.

The second attribute information D is, for example, information that captures the power consumption (power consumption curve) for each predetermined time in one day of each of the multiple first virtual power plants formed by the formation control unit 530 as the power usage status. The predetermined time may be, for example, 15 minutes or one hour. In addition, this one day may be divided into, for example, weekdays and holidays/holidays. In this case, the power consumption for each predetermined time on weekdays can be, for example, the average value of the power consumption from Monday to Friday for each predetermined time, while the power consumption for each predetermined time on holidays/holidays can be, for example, the average value of the power demand for Saturday, Sunday, and holiday for each predetermined time. When the power consumption for each predetermined time in one day is divided into weekdays and holidays/holidays, this information may be updated, for example, on a weekly basis and stored in the second attribute storage unit 520. This makes it possible to effectively use information indicating the latest power usage status of the multiple first virtual power plants in the formation of the second virtual power plant. For example, let the multiple first virtual power plants be VPP11 to VPP1n, the information showing the power usage status of each of the first virtual power plants VPP11 to VPP1n on weekdays be W31 to W3n, and the information showing the power usage status of each of the first virtual power plants VPP11 to VPP1n on holidays and public holidays be W41 to W4n.

The second attribute information E is, for example, information indicating the distribution lines F1 to F4 to which the multiple first virtual power plants VPP11 to VPP1n are respectively connected. For example, the multiple first virtual power plants VPP11 to VPP1n are associated with information on the distribution lines F1 to F4 to which they are connected, and are stored as the second attribute information E in the second attribute storage unit 520.

The second attribute information F is information indicating the geographical positions within the management area 10 in which the multiple first virtual power plants VPP11 to VPP1n are formed. Here, since each of the first virtual power plants VPP11 to VPP1n includes multiple energy resources 20A, 20B, it is desirable to regard the information indicating the geographical positions of each of the first virtual power plants VPP11 to VPP1n as information indicating the area of each of the first virtual power plants VPP11 to VPP1n. Therefore, the first integrated control unit 540 extracts address information of the energy resources 20A, 20B closest to each of the eight directions (south, southeast, east, northeast, north, northwest, west, southeast) in each of the first virtual power plants VPP11 to VPP1n from the first attribute information C, and generates octagonal area information AREA1 to AREAn. The first virtual power plants VPP11 to VPP1n are associated with octagonal area information AREA1 to AREAn, respectively, and stored in the second attribute storage unit 520 as second attribute information F. When generating the area information AREA1 to AREAn, more than eight directions (for example, 16 directions) may be used to generate the area information AREA1 to AREAn with higher accuracy.

The first integrated control unit 540 selectively integrates, via the network 30, a number of first virtual power plants VPP11 to VPP1n that are determined to be optimal when responding to demand response from among the multiple first virtual power plants VPP11 to VPP1n formed within the management area 10, by referring to the table data of the second attribute information D to F stored in the second attribute memory unit 520, to form a second virtual power plant.

The first integrated control unit 540 selectively integrates the multiple first virtual power plants VPP11 to VPP1n by using the second attribute information D and E in preference to the second attribute information F.

Here, the second attribute information D includes information indicating the amount of power consumption for each specified hour in one day of each of the first virtual power plants VPP11 to VPP1n. Therefore, the first integrated control unit 540 selects the first virtual power plants VPP11 to VPP1n that have similar power consumption from the second attribute information D, and integrates the selected first virtual power plants VPP11 to VPP1n via the network 30. As an example, when it is necessary to reduce the demand for electricity from 12:00 to 15:00 on weekdays by the lowering DR, but it is difficult to secure the demand corresponding to the lowering DR by the first virtual power plant formed by the formation control unit 530 alone, the first integration control unit 540 selects from the second attribute information D any one of the information W32 to W3n (for example, the first virtual power plant VPP12) indicating the power usage state in which the power consumption between 12:00 and 15:00 on weekdays becomes larger than a certain amount other than the already selected first virtual power plant (for example, VPP11), and forms a second virtual power plant by integrating these selected first virtual power units VPP11 and VPP12 via the network 30. In the second virtual power plant formed in this way, it is possible to efficiently reduce the power consumption by the energy resources 20A and 20B so as to secure the demand corresponding to the lowering DR between 12:00 and 15:00 on weekdays. In this way, the second attribute information D is useful information for predicting demand regarding how to control the demand of the energy resources 20A and 20B that constitute the second virtual power plant in response to demand response. Furthermore, since the first virtual power plants VPP11 to VPP1n selected from the second attribute information D have similar power usage conditions, the second attribute information D is high priority information used for the second virtual power plant to operate efficiently in one demand response.

The second attribute information E is information indicating which of the distribution lines F1 to F4 the multiple first virtual power plants VPP11 to VPP1n are connected to. As with the first attribute information B, the multiple first virtual power plants VPP11 to VPP1n connected to the distribution lines F1 and F2 (or the distribution lines F3 and F4) are likely to be affected by similar natural environments (weather, disasters, etc.). The same can be said for the first virtual power plants VPP11 to VPP1n commonly connected to any one of the distribution lines F1 to F4. Therefore, the first virtual power plants VPP11 to VPP1n connected to at least one of the distribution lines F1 and F2 or at least one of the distribution lines F3 and F4 are likely to have similar power usage conditions, and therefore are high priority information used by the second virtual power plant to operate efficiently in one demand response.

The second attribute information F is information indicating the geographical positions of the first virtual power plants VPP11 to VPP1n. Depending on the conditions of the demand response, the first virtual power plants VPP11 to VPP1n formed in a geographically close position (e.g., the first virtual power plants VPP11 to VPP1n connected to the distribution lines F1 and F2) or the first virtual power plants VPP11 to VPP1n distributed in a geographically distant position (e.g., the first virtual power plants VPP11 to VPP1n connected to the distribution lines F1 and F4) can be used as information for forming the second virtual power plant. In order to balance the amount of power demand consumed by consumers against the amount of power supply, the second attribute information D and E are used preferentially over the second attribute information F in this embodiment.

In this embodiment, the second attribute information D to F is used, but the attribute information is not limited to this. As with the first attribute information A to C, in addition to the second attribute information D to F, for example, weather forecast information, event information, hazard information, etc. for the area in which the first virtual power plants VPP11 to VPP1n are formed may be used as appropriate to selectively integrate multiple first virtual power plants VPP11 to VPP1n.

If, for example, one of the energy resources 20A and 20B in the virtual power plant breaks down or reaches the limit of supply and demand adjustment while the first virtual power plant formed by the formation control unit 530 or the second virtual power plant formed by the first integrated control unit 540 is adjusting supply and demand in response to a demand response, the virtual power plant will be unable to respond to the demand response. Therefore, the formation control unit 530 and the first integrated control unit 540 determine whether or not the virtual power plant is unable to respond to the demand response while responding to the demand response. For example, the formation control unit 530 and the first integrated control unit 540 may monitor the operating state of the energy resources 20A and 20B via the relay system 40, or may monitor whether or not the total demand of the virtual power plant has reached a certain demand for the demand response. If the formation control unit 530 and the first integrated control unit 540 determine based on the above monitoring results that the virtual power plant is unable to respond to the demand response, they output a determination signal indicating this to the second integrated control unit 550.

When the formation control unit 530 and the first integrated control unit 540 form a virtual power plant, the first virtual power plant or the energy resources 20A and 20B that are not integrated into this virtual power plant exist in the management area 10. When the second integrated control unit 550 receives the above-mentioned determination signal from the formation control unit 530 and the first integrated control unit 540, it expands the scale by integrating a new first virtual power plant or energy resource 20A or 20B into the current virtual power plant so that the virtual power plant can respond to the demand response again. For example, when the virtual power plant is unable to respond to the lowering DR, the second integrated control unit 550 selects the first virtual power plant or the energy resource 20A or 20B that can reduce the demand during the lowering DR time period and integrates it into the current virtual power plant to form the virtual power plant VPP'. This enables the virtual power plant VPP' to reliably respond to the demand response.

Figure 5 is a flowchart showing an example of a series of operations of the formation control unit 530 when forming the first virtual power plant, the first integrated control unit 540 when forming the second virtual power plant, and the second integrated control unit 550 when expanding the scale of the virtual power plant. For ease of explanation, the first attribute information A and B stored in the first attribute storage unit 510 is used when forming the first virtual power plant, and the second attribute information D and E stored in the second attribute storage unit 520 is used when forming the second virtual power plant. The demand response is, for example, a reduction DR, which is a command to reduce the power consumption by a certain amount from 12:00 to 15:00 on weekdays as described above.

First, the formation control unit 530 determines whether or not a demand response has been received from the electric utility server 60 (step S10). If the formation control unit 530 has not received a demand response (step S10: NO), it repeats the determination operation of step S10 until a demand response is received. On the other hand, if the formation control unit 530 has received a demand response (step S10: YES), it refers to the table data of the first attribute information A stored in the first attribute storage unit 510, and selects information in which the amount of power consumption between 12:00 and 15:00 has increased by more than a certain amount from the information W11 to W1n indicating the power usage situation on weekdays (step S20).

Next, the formation control unit 530 refers to the table data of the first attribute information B stored in the first attribute memory unit 510, and roughly classifies the energy resources 20A, 20B corresponding to the information W11 to W1n selected from the first attribute information A, which indicates that the amount of power consumption increases to a certain level or more between 12:00 and 15:00 on weekdays, into groups connected to the respective distribution lines F1 to F4 (step S30).

Next, the formation control unit 530 connects the energy resources 20A, 20B in each of the roughly divided groups via the network 30 to form a plurality of first virtual power plants (step S40). Note that in FIG. 4, only the first virtual power plant VPP11 consisting of one group connected to the distribution line F2, the first virtual power plant VPP12 consisting of another group connected to the distribution line F2, the first virtual power plant VPP13 consisting of one group connected to the distribution line F1, and the first virtual power plant VPP14 consisting of another group connected to the distribution line F1 are shown in thick solid line frames.

Next, the first integrated control unit 540 selects as a final candidate, from among the multiple first virtual power plants, the first virtual power plant (e.g., VPP11) having the largest total number of energy resources 20A and 20B (step S50). The reason for selecting the first virtual power plant VPP11 having the largest total number of energy resources 20A and 20B is that it is more likely that the energy resources 20A and 20B will be able to reduce power consumption significantly in response to one down-DR. In addition, because the power consumption required in one down-DR is, for example, on the order of megawatts, the greater the total number of energy resources 20A and 20B, the more likely it is that it will be able to respond to a down-DR.

Next, the first integrated control unit 540 determines whether or not the total demand from the energy resources 20A and 20B forming the virtual power plant (first virtual power plant VPP11) selected as the final candidate is likely to be insufficient for the lowering DR (step S60). If there is no risk of the total demand from the energy resources 20A and 20B forming the selected virtual power plant being insufficient for the lowering DR (step S60: NO), the first integrated control unit 540 sets this virtual power plant (virtual power plant VPP11) as one that responds to the lowering DR (step S70).

On the other hand, if there is a risk that the total demand from the energy resources 20A, 20B that form this virtual power plant will be insufficient for the lowering DR, i.e., if it is difficult to respond to the lowering DR (step S60: YES), the first integrated control unit 540 integrates the first virtual power plant VPP12, which has the largest total number of energy resources 20A, 20B excluding this virtual power plant (virtual power plant VPP11), via the network 30 to form a second virtual power plant, which is the new final candidate (step S80).

Then, returning to step S60, it is determined whether or not there is a possibility that the total demand amount of the energy resources 20A, 20B forming the virtual power plant integrated as the new final candidate will be insufficient for the lower DR. If there is no possibility that the demand amount of the energy resources 20A, 20B forming this virtual power plant will be insufficient for the lower DR (step S60: NO), the first integrated control unit 540 sets this virtual power plant as one that responds to the lower DR (step S70).

The virtual power plant set in step S70 (for example, the second virtual power plant in step S80) will respond to the lowering DR, but the ability of the energy resources 20A, 20B integrated into this virtual power plant to adjust the demand may decrease due to aging or the like, or these energy resources 20A, 20B may break down, causing the demand to be insufficient even while the virtual power plant is responding to the lowering DR, and the virtual power plant may not be able to fully respond to the lowering DR. Therefore, the first integrated control unit 540 determines whether the demand of this virtual power plant is insufficient for the lowering DR even while the virtual power plant is responding to the lowering DR (step S90).

If the demand of the virtual power plant is insufficient for the lowering DR (step S90: YES), the first integrated control unit 540 outputs a judgment signal indicating this to the second integrated control unit 550. The second integrated control unit 550, which has received this judgment signal, integrates and expands the reserve energy resources 20A and 20B, for example, the first virtual power plant VPP14, to this virtual power plant in order to obtain a demand that can respond to the lowering DR, thereby forming a virtual power plant VPP' (step S100). On the other hand, if the demand of the virtual power plant is not insufficient for the lowering DR (step S90: YES), step S100 is not executed. Then, the first integrated control unit 540 returns to step S90 and repeats the same process.

Figure 6 is a flow chart showing an example of an automated demand response flow. Here, the aggregator server 50 forms a second virtual power plant, but the energy resources 20A and 20B that make up this second virtual power plant alone are insufficient to respond to the lowered DR even while responding to the lowered DR, so the second virtual power plant is expanded to form a virtual power plant VPP' to deal with the situation.

First, a demand response indicating the above-mentioned reduced DR is generated from the electric utility server 60 (step S200).

Next, when the aggregator server 50 receives this lowering DR on a weekday (step S210), it forms a plurality of first virtual power plants VPP11 to VPP1n based on the first attribute information A and B in the procedure shown in FIG. 5, and forms a second virtual power plant by integrating the plurality of first virtual power plants VPP11 to VPP1n capable of responding to the lowering DR via the network 30 based on the second attribute information D and E. In addition, since the second virtual power plant has a reduced ability to adjust the demand amount in any of the energy resources 20A and 20B integrated as the second virtual power plant while responding to the lowering DR, the aggregator server 50 expands the second virtual power plant to set the virtual power plant VPP' as a virtual power plant that responds to the lowering DR (step S220). Here, in FIG. 5, the procedure using the first attribute information A and B when forming the first virtual power plant is shown, but depending on the conditions of the lowered DR, the first attribute information C may be used in addition to the first attribute information A and B in order to more reliably respond to the lowered DR. For example, the first attribute information C is useful information when it is desired to further narrow down the geographical area of the first virtual power plant. In this way, the aggregator server 50 forms the first virtual power plant using at least one of the first attribute information A, B, and C. For example, depending on the conditions of the DR, the aggregator server 50 may form the first virtual power plant using only the first attribute information A without using the first attribute information B, or may form the first virtual power plant using the first attribute information A and C. Similarly, when forming the second virtual power plant, in addition to the second attribute information D and E, the second attribute information F may be used.

When the formation of the virtual power plant VPP' is completed, the first integrated control unit 540 instructs the multiple energy resources 20A, 20B that form the virtual power plant VPP' to reduce their power consumption by a certain amount between 12:00 and 15:00 on weekdays in accordance with the reduction DR. This instruction is given to the relay system 40 connected to the energy resources 20A, 20B, which controls the reduction in power consumption by the energy resources 20A, 20B to reach a certain amount (step S230). For example, if the energy resources 20A, 20B are lighting equipment or air conditioning equipment, control is automatically performed to suppress the output of these equipment.

When the period for reducing power consumption within the virtual power plant VPP' (12:00 to 15:00 on weekdays) has elapsed, the first integrated control unit 540 acquires and compiles actual data indicating the amount of reduction in power consumption from the relay systems 40 connected to the energy resources 20A, 20B that have reduced their power consumption within the virtual power plant VPP', and transmits this compiled data to the electric utility server 60 (step S240).

When the electric utility server 60 acquires the aggregated data from the first integrated control unit 540, it performs a process to pay the aggregator server 50 a remuneration according to the amount of reduction in power consumption indicated by the aggregated data (step S250). After confirming through the aggregator server 50 that the process of receiving the remuneration according to the amount of reduction in power consumption has been completed, the aggregator pays the above-mentioned remuneration to the consumer who owns the energy resources 20A, 20B in the virtual power plant VPP', thereby completing the series of negawatt transactions. Of course, whether or not a remuneration is paid to the consumer in response to a demand response depends on the contents of the consumer's contract, and this embodiment is merely an example.

In this embodiment, while the second virtual power plant is responding to the lowering DR, the first virtual power plant VPP14 is integrated with the second virtual power plant to form a virtual power plant VPP' and respond to the lowering DR, but this is not limited to the above. For example, if the first virtual power plant selected in step S50 of FIG. 5 is the virtual power plant (e.g., VPP11) set in step S70, the first virtual power plant VPP14 set as a reserve may be integrated with the first virtual power plant VPP11 to respond to the lowering DR, or one of the energy resources 20A and 20B that are not integrated with either virtual power plant may be integrated with the first virtual power plant VPP11 to resolve the shortage of demand for the lowering DR.

As described above, the integrated control system for a virtual power plant integrates and controls multiple energy resources 20A, 20B owned by multiple consumers X1 to Xn and distributed in various locations via a network 30, and functions as if they were a single power plant. This system includes an attribute memory unit (first attribute memory unit 510, second attribute memory unit 520) that stores attribute information (first attribute information A to C, second attribute information D to F) including information related to the multiple energy resources 20A, 20B, and a virtual power plant (first virtual power plan) that selectively integrates the energy resources 20A, 20B from among the multiple energy resources based on the attribute information. The system includes a first integrated control unit (forming control unit 530, first integrated control unit 540) that forms a virtual power plant VPP' and controls the virtual power plant in response to demand response, and a second integrated control unit 550 that integrates spare energy resources 20A, 20B (including those integrated as the first virtual power plant) that are not integrated into the virtual power plant to form a virtual power plant VPP' when the virtual power plant is no longer able to respond to the scale of supply and demand adjustment in the demand response, so that the virtual power plant can respond to the demand response.

In addition, an integrated control system for a virtual power plant that integrates and controls multiple energy resources 20A, 20B owned by multiple consumers X1 to Xn and distributed in various locations via a network 30 to function as if they were a single power plant, includes a first attribute storage unit 510 that stores first attribute information A to C including information related to the multiple energy resources 20A, 20B, a formation control unit 530 that selectively integrates the energy resources 20A, 20B from among the multiple energy resources 20A, 20B based on the first attribute information A to C to form multiple first virtual power plants, a second attribute storage unit 520 that stores second attribute information D to F including information related to the multiple first virtual power plants, and a control unit 530 that controls the multiple first virtual power plants. The system includes a first integrated control unit 540 that selectively integrates first virtual power plants from among a number of first virtual power plants based on second attribute information D to F to form a second virtual power plant larger in scale than the first virtual power plant and controls the second virtual power plant in response to demand response, and a second integrated control unit 550 that integrates a spare first virtual power plant that is not integrated with the second virtual power plant with the second virtual power plant so that the second virtual power plant can respond to demand response when the second virtual power plant is no longer able to respond to the scale of supply and demand adjustment in demand response, to form a virtual power plant VPP'.

The first attribute information A also includes information indicating the power usage status of multiple consumers X1 to Xn.
The first attribute information B also includes information indicating the power grid to which the multiple energy resources 20A, 20B are connected.

The first attribute information C also includes information indicating the geographical locations of the multiple energy resources 20A and 20B.

The second attribute information D also includes information indicating the power usage status of the multiple first virtual power plants.

The second attribute information E also includes information indicating the power grid to which the multiple first virtual power plants are connected.

The second attribute information F also includes information indicating the geographical locations of the multiple first virtual power plants.

The formation control unit 530 also prioritizes the first attribute information A and B over the first attribute information C among the first attribute information A to C, and selectively integrates the energy resources 20A and 20B to form multiple first virtual power plants.

The first integrated control unit 540 also prioritizes second attribute information D and E over second attribute information F among the second attribute information to form the second virtual power plant.

In this way, according to this embodiment, regardless of the urban area 10A or the surrounding area 10B, various energy resources 20A and 20B that are ubiquitous are efficiently utilized to form a first virtual power plant, and a second virtual power plant that is larger in scale than the first virtual power plant depending on the amount of demand required by the demand response. Then, even if, for example, the ability to adjust the amount of demand is reduced in any of the energy resources 20A and 20B integrated into the second virtual power plant while the second virtual power plant is responding to the demand response, or if any of the energy resources 20A and 20B breaks down, the first virtual power plant VPP14 prepared as a backup for the second virtual power plant can be integrated to continue responding to the demand response, making it possible to further ensure the balance of the supply and demand of electricity.

The above embodiment is intended to facilitate understanding of the present invention, and is not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit of the present invention, and equivalents thereof are also included in the present invention.

In this embodiment, the second virtual power plant operates to reduce the amount of power consumption according to the lowering DR, but this is not limited to the above. The second virtual power plant can also operate to increase the amount of power consumption according to the increasing DR. In other words, the aggregator server 50 can form and control the virtual power plant VPP' so as to efficiently respond to both the increasing DR and the decreasing DR.

In addition, in this embodiment, a virtual power plant capable of responding to demand response is formed in a so-called two-stage manner, in which a plurality of first virtual power plants are formed in a first stage, and a second virtual power plant is formed by integrating the plurality of first virtual power plants in a second stage, but this is not limited to the above. For example, as shown in the flowchart of FIG. 5, when forming a second virtual power plant, a multi-stage integration of two or more stages may be performed in which a plurality of first virtual power plants are repeatedly integrated until a demand amount capable of responding to demand response can be secured.

In addition, in this embodiment, the case where one second virtual power plant is formed has been described, but the present invention is not limited to this. For example, a plurality of second virtual power plants formed in the manner described above may be formed, and a wide-ranging virtual power plant may be formed by integrating the plurality of second virtual power plants in multiple stages based on the attributes described above. In this case, it becomes possible to perform control using virtual power plants of various scales, from the scale of a city, town, or village to the scale of a prefecture.
