Description

The present invention relates to a power management device, a terminal device, a power management method, and a power management program.

Conventionally, a system for managing power consumption in a power demand facility has been developed so that power consumption in a power demand facility such as a general household or an office is suppressed when the power supply and demand is tight.

For example, Patent Document 1 (Japanese Unexamined Patent Publication No. 2012-205358) discloses the following techniques. That is, the power management system has a holding unit that holds a list of participants related to a community including a plurality of pre-registered participants, a determination unit that determines whether or not power reduction control should be executed, and a power reduction control execution unit. When the judgment unit determines that it is necessary, the selection unit and the selection unit select one or more target persons to be targeted for power reduction control from a plurality of participants included in the participant list. It is provided with a control unit that executes power reduction control for the selected target person, and a granting unit that grants a privilege based on the reduced power consumption to the target person for which the power reduction control is executed.

Further, for the purpose of saving electricity, an energy management system xEMS (Energy Management System) has been introduced into electric power demand facilities such as homes or buildings.

The xEMS is a system for controlling the power consumption in the power demand facility by monitoring the power consumption in the power demand facility and managing the operating state of the equipment or the equipment in the power demand facility. The xEMS is HEMS (Home Energy Management System) for home use and BEMS (Billing Energy Management System) for buildings.

xEMS realizes suppression of electric power demand by cooperating with a VPP (Virtual Power Plant) operator, that is, an operator called an aggregator, for example. The aggregator will provide energy management support services to power demand facilities that have introduced xEMS.

Further, for example, a technique for preventing reverse power flow (power sale) to the grid of the generated power by the power generation device in the power demand facility such as solar power generation provided in a general household has been developed.

For example, Patent Document 3 (Japanese Unexamined Patent Publication No. 2013-172495) discloses a power storage type power generation system capable of utilizing generated power without waste. The power storage type power generation system is a power generation unit that is connected to an external system and receives natural energy to generate power, and a power storage unit that stores the power generated by the power generation unit and the power from the system and is connected to the power generation unit by DC. And a control unit that controls the power generation of the power generation unit and the charge / discharge to the power storage unit. When the generated power is reverse power flow toward the grid, the control unit stops the reverse power flow of the generated power or reverse power generation based on the comparison between the grid voltage and the predetermined threshold voltage. While reducing the electric power, the generated electric power is charged to the storage battery.

Further, for example, in Patent Document 4 (Japanese Unexamined Patent Publication No. 11-299110), when a private power generator and a commercial power source are operating in parallel, power reverse power flow due to sudden load fluctuation is applied to the generator or engine. A power reverse power flow prevention device that prevents power generation without imposing a heavy burden is disclosed. In the power reverse power flow prevention device, the engine governor adjusts the fuel supply amount to the generator drive engine of the private power generation facility according to the speed. The speed control means controls the fuel supply amount of the engine governor so as to adjust the speed of the engine for driving the generator according to the predicted value of the load fluctuation. The received power detecting means detects the power received from the commercial power source. Then, the high-speed control means responds to the output from the received power detecting means, and when the reduced state of the received power with respect to the preset minimum received power value continues so as to satisfy the predetermined condition for the received power reduction time, the speed is reached. The control of the engine governor by the control means is stopped, and the engine governor is controlled within the allowable time of reverse power flow so that the fuel supply amount corresponds to the preset reduction of the received power amount, and the received power is predetermined. When the recovery condition is satisfied, the control of the engine governor by the speed control means is restored.

For example, a power transmission and distribution business operator and an electric power retailer make a power saving request to an aggregator in advance when a tight supply and demand of electric power is predicted. Then, the aggregator makes a power saving request to the consumer of the electric power demand facility.

Also, for example, if the power supply is expected to exceed the demand, the power transmission and distribution business operator will reduce the amount of power generation to the renewable energy business operator and the consumer who owns the power generation equipment. Request to suppress.

<First Embodiment>
[Configuration and basic operation]
FIG. 1 is a diagram showing a configuration of a power management system according to the first embodiment of the present invention.

With reference to FIG. 1, the power management system 301 includes a power management server (power management device) 101, a system side server 121, a terminal device 171 and three consumer devices 202.

Although FIG. 1 typically shows three consumer devices 202, a larger number or a smaller number of consumer devices 202 may be provided. Further, although the two loads 205 are typically shown corresponding to the consumer device 202, a larger or smaller number of loads 205 may be provided corresponding to the consumer device 202.

In the power management system 301, for example, when the supply and demand of electric power is tight, or when the supply and demand of electric power is likely to be tight, each consumer issues a demand response (DR: Demand Response) for suppressing power consumption. It is possible to do.

The grid-side server 121 in the power management system 301 is operated by a power transmission and distribution business operator, a power retailer, or the like on the power system side, and transmits suppression information S1 indicating a request for suppression of power consumption to the power management server 101. The suppression information S1 includes, for example, the start timing of the request period for suppressing power consumption (hereinafter, also referred to as a DR period), the length of the DR period, and the requested power R1 indicating the amount of suppression of power consumption. The suppression information S1 may include the end timing of the DR period instead of the length of the DR period.

The consumer device 202 is used in an electric power demand facility such as a building, a factory, or a general household, which receives electric power from an electric power company. One consumer device 202 may be provided for each power demand facility, or a plurality of consumer devices 202 may be provided for each power demand facility. An electric power company is, for example, a power generation company or an electric power retailer.

The consumer device 202 can control one or more loads 205 in the power demand facility. The load 205 is a secondary battery-powered electric vehicle and a plug-in hybrid vehicle using a secondary battery as an energy source, and electric devices such as lighting, a television, and an air conditioner.

More specifically, the consumer device 202 is a device used in xEMS for reducing power consumption by controlling the operation of an electric device, and is introduced by, for example, an aggregator.

The power management server 101 is operated by, for example, an aggregator, and manages power consumption in one or more power demand facilities by communicating with one or more consumer devices 202. The power management server 101 is often installed at a location remote from the power demand facility where the consumer device 202 is provided, for example.

In this example, the communication unit 21 can transmit / receive information to / from the wholesale power exchange server 111, the grid side server 121, the terminal device 171 and the consumer device 202.

The storage unit 23 holds management information, performance aggregation information, DR possible amount information, and various registration information. The DR possible amount information and various registration information will be described later.

Here, the management information includes, for example, a consumer ID of each consumer managed by the aggregator, and a contract content, a schedule, and an apparatus ID of the consumer apparatus 202 corresponding to the consumer ID. For example, the consumer ID belongs to a group according to the contract contents. Each of these contracts provides incentives for power savings. The schedule indicates, for example, the period during which the consumer cannot participate in the DR.

The performance aggregate information shows, for example, the DR performance of each consumer. Specifically, the actual aggregate information includes the DR period and the requested power R1 requested from the system side server 121 for each customer ID, and the actual value of the power saved in the period.

The processing unit 22 periodically predicts, for example, the DR possible amount of each consumer managed by its own power management server 101.

[Recommendation processing RP1]
FIG. 6 is a diagram showing an example of a sequence of recommendation processing in the power management system according to the first embodiment of the present invention. FIG. 6 shows the details of the operation in step S104 of FIG.

With reference to FIGS. 2 to 4 and 6, it is assumed that the display control unit 62 in the terminal device 171 controls to display the screen Sc1 shown in FIG. 4 on the display device.

First, the terminal device 171 performs an input reception process (step S702).

More specifically, the operator refers to, for example, the screen Sc1 and performs an operation of inputting at least a "control period" to the terminal device 171. Here, the "control period" is, for example, a period during which the aggregator participates in the DR, and can be specified in units of 30 minutes.

In addition, the operator can specify "control amount" and "control condition" as options. Here, the "control amount" indicates the target of power saving in the "control period".

The "control condition" indicates the condition of the request destination, that is, the consumer. Specifically, the "control condition" is a method for extracting consumers such as the number of consumers to be extracted, the area where the power demand facility of the consumer to be extracted is located, and the turn number and priority order. Designation and whether or not consumers have participated in DR in the past period.

When the input of each item is completed, the operator performs an operation of selecting the "execute" button.

The reception unit 64 in the terminal device 171 accepts the operator's operation, creates operation information indicating the accepted operation, and outputs the operation information to the notification unit 65.

Next, when the notification unit 65 receives the operation information from the reception unit 64, the notification unit 65 transmits the received operation information to the power management server 101 (step S704).

Next, the power management server 101 performs a candidate information creation process (step S706).

The processing unit 22 in the power management server 101 creates a plurality of candidate information indicating the request destination and the content of the suppression of power consumption.

More specifically, the processing unit 22 creates candidate information prior to receiving the suppression information S1, for example.

The processing unit 22 creates a plurality of candidate information based on, for example, the content of suppressing power consumption and the condition information indicating the condition of the request destination.

Specifically, the processing unit 22 creates candidate information based on, for example, a control period and control amount indicating a period and amount of power consumption suppression, condition information, and a schedule of a request destination, that is, a schedule included in management information. do.

Further, the processing unit 22 creates candidate information so that one or a plurality of request destinations indicated by the candidate information are different between at least two candidate information, for example.

Specifically, when the processing unit 22 receives the operation information from the terminal device 171 via the communication unit 21, the processing unit 22 recognizes the control period and the control amount as the content of suppressing the power consumption based on the received operation information. For example, when the operator does not specify the "control amount", the processing unit 22 uses the DR possible amount in the control period based on the DR possible amount information as the control amount.

Further, the processing unit 22 acquires the "control condition" specified by the operator from the operation information as the condition information, and recognizes the content of the acquired condition information. For example, when the operator does not specify the "control condition", the processing unit 22 uses at least one of the above-mentioned "control conditions" as the default condition information.

The processing unit 22 creates a plurality of candidate information different from each other based on the management information and the result aggregation information in the storage unit 23, as well as the control period, the control amount, and the condition information.

Specifically, the processing unit 22 determines a request destination to be included in the candidate information, for example, based on the content of the suppression of power consumption and the condition information.

More specifically, the processing unit 22 tentatively determines the request destination based on the content of the suppression of power consumption, and includes the request destination to be included in the candidate information from the tentatively determined request destinations based on the condition information. decide.

Specifically, the processing unit 22 creates input data including the DR performance, schedule, control period and control amount of each consumer by using, for example, management information, performance aggregation information, control period and control amount. .. Further, the processing unit 22 creates control condition data including the contents of the condition information.

The processing unit 22 has, for example, an optimization engine, and by inputting the created input data and control condition data to the optimization engine, the consumer ID of each consumer who satisfies the input data is provisionally set. Extract.

From the provisionally extracted consumer IDs of each consumer, the processing unit 22 actually extracts the consumer IDs of each consumer that satisfy the conditions indicated by the condition information.

Specifically, the processing unit 22 has, for example, 70 customer IDs of each consumer, 100 customer IDs of each customer, and 150 customer IDs that satisfy the input data. Temporarily extract the consumer IDs of any number of consumers such as the consumer IDs.

Then, for example, when the number of consumers to be extracted is specified as 100 as the condition indicated by the condition information, the processing unit 22 has 100 customers in each set of provisionally extracted customer IDs. The customer ID of is extracted.

The processing unit 22 extracts the consumer ID of each consumer that satisfies the input data and the control condition based on the content of the suppression of power consumption and the condition information without tentatively determining the request destination. You may. This determination method is suitable, for example, when the area where the power demand facility of the consumer to be extracted is located is specified as the condition indicated by the condition information.

Further, the processing unit 22 may determine the request destination based on the content of suppressing the power consumption without using the condition information. Specifically, the processing unit 22 may extract the customer ID of each customer that satisfies the control period and the control amount by the turn number, or may randomly extract the customer ID.

The processing unit 22 calculates the power saving power to be allocated to each extracted consumer, the total of the allocated power saving power, that is, the expected power saving power, and the total of the incentives to be paid to each of the extracted consumers, that is, the cost.

Then, the processing unit 22 creates, for example, three candidate information including the extracted consumer ID, the calculated power saving power, the expected power saving power value, and the cost, and indexes the three created candidate information.

Next, the processing unit 22 creates processing result information including three candidate information and a control amount, and transmits the created processing result information to the terminal device 171 via the communication unit 21. The acquisition unit 61 in the terminal device 171 acquires a plurality of candidate information from the power management server 101. More specifically, the acquisition unit 61 receives the processing result information from the power management server 101 (step S708).

Next, the terminal device 171 performs a display process (step S710). Specifically, the acquisition unit 61 in the terminal device 171 outputs the received processing result information to the display control unit 62.

More specifically, the processing unit 22 in the power management server 101 creates request information of the content based on the candidate information selected from the three candidate information created by itself.

Here, since the DR is not urgent, the processing unit 22 receives the operation information from the terminal device 171 via the communication unit 21 and creates the request information based on the received operation information.

More specifically, the processing unit 22 recognizes that the candidate information having an index of 1 is selected by the operator based on the operation information, and from the candidate information having an index of 1, each customer ID and each demand thereof. Acquire the power saving power to be allocated to the consumer indicated by the house ID.

Then, the processing unit 22 acquires the device ID corresponding to each acquired consumer ID as the destination of the request information from the management information, and includes the corresponding destination, the DR period, and the corresponding power saving power for each device ID. Create request information.

On the other hand, in the case of an urgent DR (YES in step S802), the processing unit 22 selects candidate information from the three candidate information created by itself according to the designated criteria, and the content based on the selected candidate information. Create request information for. Here, the specified criteria are, for example, "expected achievement rate (%)", "expected power reduction amount (kW)", "total payment incentives (yen)" and "selected resources" shown in FIG. It is a standard using any one of "the number of".

The processing unit 22 outputs each created request information to the communication unit 21.

With reference to FIG. 5 again, the communication unit 21 then notifies the request destination of the request information of the content based on the candidate information selected from the candidate information created by the processing unit 22 (step S116). ..

More specifically, when the communication unit 21 receives each request information from the processing unit 22, each request information received is transmitted to the consumer device 202 indicated by the destination included in each request information.

Next, when each consumer device 202 receives the request information from the power management server 101, it performs a request information registration process for registering the received request information (step S118).

Next, each consumer device 202 transmits response information indicating whether or not to permit the contents of the request information to the power management server 101 (step S120).

Next, each consumer device 202 periodically transmits the actual value information indicating the actual result of its own DR to the power management server 101 (step S122).

Next, the processing unit 22 in the power management server 101 determines, for example, whether or not the request for suppressing power consumption can be fulfilled after the request information is notified by the communication unit 21 (step S124).

(Step S204).

Next, when the processing unit 22 determines that the achievement level has not reached the target (YES in step S206), the processing unit 22 performs the recommendation processing RP3 (step S208). Here, since DR is being executed, the processing unit 22 performs the recommendation processing RP3 without making an inquiry to the operator, for example.

More specifically, the processing unit 22 creates, for example, three candidate information. Specifically, the processing unit 22 creates, for example, candidate information in which the number of customer IDs included in the candidate information created before the start of DR (hereinafter, also referred to as pre-start candidate information) is increased or decreased. Create candidate information that includes customer IDs that are not included in the pre-start candidate information in the pre-start candidate information, or create candidate information that includes the customer IDs of consumers that belong to other groups in the pre-start candidate information. Or something.

Then, the processing unit 22 selects candidate information from the three candidate information created by itself according to, for example, a designated criterion.

The processing unit 22 creates request information for each consumer whose DR contents are to be changed based on the selected candidate information and management information, and outputs the created request information to the communication unit 21.

Next, when the communication unit 21 receives each request information from the processing unit 22, each request information received is transmitted to the consumer device 202 indicated by the destination included in each request information (step S210).

Next, when each consumer device 202 whose DR content is to be changed receives the request information from the power management server 101, the request information registration process for registering the received request information is performed (step S212).

Next, each consumer device 202 whose contents of the DR are to be changed executes the DR according to the request information (step S214).

On the other hand, when the processing unit 22 determines that the achievement level has reached the target (NO in step S206), the processing unit 22 does not perform the recommendation processing RP3.

The processing of steps S204 to S214 is repeated, for example, periodically until DR is completed.

Next, each consumer device 202 periodically transmits the actual value information to the power management server 101 after the DR is executed (step S216).

Next, the power management server 101 performs aggregation processing. More specifically, the processing unit 22 in the power management server 101 receives the actual value information from each consumer device 202 via the communication unit 21, and participates in the DR based on the actual value information and the suppression information S1. The results of power saving in the DR period of the consumer are totaled (step S218).

Next, the power management server 101 performs the update process. More specifically, the processing unit 22 updates the performance aggregation information in the storage unit 23 based on the aggregation result (step S220).

Next, the processing unit 22 transmits the actual value information including the total value of the actual power saving power in the DR period of each consumer who participated in the DR to the system side server 121 via the communication unit 21 (step S222).

Next, when the system side server 121 receives the actual value information from the power management server 101, the system side server 121 performs an actual value registration process for registering the contents of the received actual value information (step S224).

Candidate information may be created based on at least one of the control amounts.

By the way, for example, power transmission and distribution business operators and electric power retailers can easily adjust the overall electric power demand in a wide range by introducing xEMS in many electric power demand facilities.

For example, a power transmission and distribution business operator and an electric power retailer make a power saving request to an aggregator in advance when a tight supply and demand of electric power is predicted. Then, the aggregator makes a power saving request to the consumer of the electric power demand facility.

Also, for example, if the power supply is expected to exceed the demand, the power transmission and distribution business operator will reduce the amount of power generation to the renewable energy business operator and the consumer who owns the power generation equipment. Request to suppress.

However, if the content of the request to the renewable energy company and the consumer is not appropriate, the supply and demand of electric power becomes tight, the supply of electric power exceeds the demand, and the balance of supply and demand of electric power in the grid is disturbed, which is not preferable.

Further, in the power management server according to the first embodiment of the present invention, the processing unit 22 sets the request destination to be included in the candidate information based on the content of the suppression of power consumption and the condition information indicating the condition of the request destination. decide.

With such a configuration, for example, the content of suppression and conditions such as the actual performance, region, and priority of the request destination can be set, so that more appropriate candidate information can be recommended.

Further, in the power management server according to the first embodiment of the present invention, the processing unit 22 creates candidate information based on the schedule of the request destination.

With such a configuration, for example, it is possible to create candidate information excluding periods that are inconvenient for the requestee, thus increasing the possibility that power consumption or power supply to the grid will be suppressed as planned. Can be done.

Further, in the power management server according to the first embodiment of the present invention, the processing unit 22 creates candidate information based on at least one of a period and an amount of suppression of power consumption.

With such a configuration, candidate information that reflects the target can be created, so that it is possible to increase the possibility that power consumption is suppressed according to the target.

Further, the power management server according to the first embodiment of the present invention receives suppression information S1 indicating a request for suppression of power consumption from another device. Then, the processing unit 22 creates candidate information prior to receiving the suppression information S1.

With such a configuration, for example, the executable content based on the candidate information selected in the power management server 101 can be notified to other devices, so that the feasibility of the content of the suppression information S1 can be enhanced. .. As a result, the content of the suppression information S1 can be smoothly executed.

Further, the power management server according to the first embodiment of the present invention receives suppression information S1 indicating a request for suppression of power consumption from another device. Then, after the request information is notified by the communication unit 21, the processing unit 22 creates new candidate information when it is determined that the request cannot be achieved.

With such a configuration, when the suppression is not performed according to the content of the suppression information S1, the request destination and the request amount can be added or reduced, so that the feasibility of the content of the suppression information S1 can be improved. Can be enhanced.

Further, in the terminal device according to the first embodiment of the present invention, the acquisition unit 61 is a power management server that manages power consumption by displaying candidate information indicating at least one of the request destination and the content of the request for suppressing power consumption. Obtain multiple items from 101. Then, the notification unit 65 notifies the power management server 101 of the candidate information selected from the candidate information acquired by the acquisition unit 61.

With such a configuration, for example, various candidate information acquired from the power management server 101 can be recommended to the user, so that the user can select the candidate information that suits his / her taste. Then, by the configuration of notifying the power management server 101 of the candidate information selected by the user, for example, the power management server 101 can notify the request destination of the request information having more appropriate contents based on the selected candidate information.

FIG. 13 is a diagram showing an example of a sequence of each process before execution of PV output suppression in the power management system according to the second embodiment of the present invention.

With reference to FIG. 13, first, the retailer server 151 periodically notifies the power transmission and distribution business server 141 of the demand plan value for each predetermined period (step S302).

Next, the renewable energy business server 131 periodically notifies the power transmission and distribution business server 141 of the forecast of the planned value of the power generation amount for each predetermined period (step S304).

Next, the power transmission and distribution business server 141 determines whether or not it is necessary to suppress the power supply to the grid based on the content of each notification notified from the retail business server 151 and the renewable energy business server 131. Perform the process (step S306). Here, the power transmission and distribution business operator server 141 determines that it is necessary to suppress the power supply to the grid.

Next, the power transmission and distribution business operator server 141 transmits the suppression information S2 to the power management server 102 (step S308).

Next, the power transmission and distribution business operator server 141 transmits the suppression information S3 to the renewable energy business operator server 131 (step S310).

Next, when the renewable energy business server 131 receives the suppression information S3 from the power transmission and distribution business server 141, it performs a suppression information registration process for registering the received suppression information S3 (step S312).

Next, the power management server 102 performs the suppression information registration process (step S314).

When the processing unit 32 receives the suppression information S2 from the communication unit 21, the processing unit 32 stores the received suppression information S2 in the storage unit 23.

Next, the consumer device 202 periodically transmits the solar radiation amount information indicating the current and future solar radiation amount in its own power demand facility to the power management server 102 (step S316).

Next, the power management server 102 performs the power generation amount prediction process (step S318). More specifically, the processing unit 32 in the power management server 102 predicts the amount of power generation in the PV suppression period included in the suppression information S2 based on the solar radiation amount information received from the consumer device 202 via the communication unit 21.

Next, the processing unit 32 determines, for example, whether or not to respond to the request indicated by the suppression information S2 based on the predicted power generation amount (step S320).

More specifically, the processing unit 32 determines whether or not the suppression of the requested power R2 can be achieved during the PV suppression period using the predicted power generation amount. Specifically, the processing unit 32 determines that the suppression of the requested power R2 cannot be achieved when the predicted power generation amount is small because the amount of solar radiation is small, and determines that the request indicated by the suppression information S2 is not accepted. Further, the processing unit 32 determines that the suppression of the requested power R2 is achievable when the predicted power generation amount is large because the amount of solar radiation is large, and determines that the request indicated by the suppression information S2 is accepted.

When the processing unit 32 determines that the request indicated by the suppression information S2 is not accepted (NO in step S320), the processing unit 32 transmits the unlicensed response signal to the power transmission and distribution business operator server 141 via the communication unit 21 (step S322).

Next, when the power transmission and distribution business operator server 141 receives the unlicensed response signal from the power management server 102, the power transmission and distribution business operator server 141 performs a recording process of recording the received unlicensed response signal (step S324).

On the other hand, when it is determined that the request indicated by the suppression information S2 is to be accepted (YES in step S320), the processing unit 32 performs the recommendation processing RP4 (step S326).

[Recommendation processing RP4]
FIG. 14 is a diagram showing an example of a sequence of recommendation processing in the power management system according to the second embodiment of the present invention. FIG. 14 shows the details of the operation in step S326 of FIG.

With reference to FIGS. 3, 12, and 14, first, the power management server 102 performs a candidate information creation process (step S900).

More specifically, the processing unit 32 in the power management server 102 creates a plurality of candidate information indicating the request destination and the content of suppressing the power supply to the grid.

The processing unit 32 creates a plurality of candidate information based on, for example, the content of suppressing the power supply to the grid and the condition information indicating the condition of the request destination.

Here, the condition information indicates, for example, the condition of the request destination, here the customer, and is registered in advance by the operator. Specifically, the conditions of the consumer are, for example, the designation of the number of consumers to be extracted, the designation of the area where the power demand facility of the consumer to be extracted is located, the extraction of consumers such as the turn number and the order of priority. The designation of the method and whether or not the consumer has participated in the suppression of PV output in the past period.

Specifically, the processing unit 32 is based on, for example, a PV suppression period indicating the period and amount of suppression of power supply to the grid, the requested power R2, condition information, and the schedule included in the request destination schedule, that is, the management information. Create candidate information.

Further, the processing unit 32 creates candidate information so that one or a plurality of request destinations indicated by the candidate information are different between at least two candidate information, for example.

The processing unit 32 creates a plurality of candidate information different from each other based on the management information and the result aggregation information in the storage unit 23, the PV suppression period, the requested power R2, and the condition information.

Specifically, the processing unit 32 determines a request destination to be included in the candidate information, for example, based on the content of suppressing the power supply to the grid and the condition information.

Specifically, the processing unit 32 uses, for example, management information, actual aggregation information, PV suppression period, and requested power R2 to obtain the actual PV output suppression performance, schedule, PV suppression period, and requested power R2 of each consumer. Create input data to include. Further, the processing unit 32 creates control condition data including the contents of the condition information.

For example, the processing unit 32 inputs the created input data and control condition data to the optimization engine, and extracts the consumer ID of each consumer that satisfies the input data and the control condition data.

The processing unit 32 may determine the request destination based on the content of suppressing the power supply to the system without using the condition information. Specifically, the processing unit 32 may extract the consumer ID of each consumer that satisfies the PV suppression period and the requested power R2 by a turn number, or may randomly extract it.

The processing unit 32 calculates the supply restraint power to be allocated to each extracted consumer, the total of the allocated supply restraint powers, that is, the expected supply restraint power, and the total of the incentives to be paid to each of the extracted consumers, that is, the cost.

Then, the processing unit 32 creates, for example, three candidate information including the extracted consumer ID, the calculated supply suppression power, the expected value of the supply suppression power, and the cost, and indexes the three created candidate information.

Next, when the PV output suppression is not urgent, specifically, when the time until the start timing of the PV suppression period included in the suppression information S2 is a predetermined value Th2 or less (NO in step S902). ), Perform the following processing.

That is, the processing unit 32 transmits each candidate information and the suppression information S2 to the terminal device 171 via the communication unit 21. The acquisition unit 61 in the terminal device 171 receives each candidate information and suppression information S2 from the power management server 102 (step S904).

FIG. 15 is a diagram showing an example of a screen created by a terminal device in the power management system according to the second embodiment of the present invention. FIG. 15 shows an event screen.

With reference to FIG. 15, the terminal device 171 then performs a display process (step S906). More specifically, the acquisition unit 61 in the terminal device 171 outputs each received candidate information and suppression information S2 to the display control unit 62.

When the display control unit 62 receives each candidate information and suppression information S2 from the acquisition unit 61, the display control unit 62 controls to display the screen Sc4 shown in FIG. 15 on the display device based on the received candidate information and suppression information S2.

In the graph Gr2 on the screen Sc4, the vertical axis represents electric power and the horizontal axis represents time. In this example, in the graph Gr2, a rectangle showing a control request of 200 kW from 10:00 to 12:00 is drawn based on the PV suppression period and the requested power R2 included in the suppression information S2.

Further, in the "PV output suppression plan candidate", the contents of the three candidate information are displayed in index order. The "expected achievement rate (%)" is a value expressed as a percentage of the value obtained by dividing the expected value of the supply suppression power by the requested power R2. "Expected supply restraint electric energy (kW)" and "total payment incentive (yen)" are the expected value and cost of supply restraint power, respectively. The “number of selected resources” is the number of consumer IDs extracted by the power management server 102. The "control condition" is, for example, a condition registered in advance by the operator.

Further, by performing the operation of selecting the "recreate" button on the terminal device 171, for example, it is possible to recreate a plurality of candidates and reset the "control condition". In this case, the power management server 102 performs the recommendation processing RP4, so that a plurality of candidates are recreated.

With reference to FIGS. 14 and 15, the terminal device 171 then performs an input acceptance process (step S908).

More specifically, the operator refers to the screen Sc4 and, for example, performs an operation of selecting the "select this candidate" button corresponding to No. 1 to the terminal device 171.

The reception unit 64 accepts the operator's operation, creates operation information indicating the accepted operation, and outputs the created operation information to the notification unit 65.

When the notification unit 65 receives the operation information from the reception unit 64, the notification unit 65 transmits the received operation information to the power management server 102 (step S910).

Next, the power management server 102 performs a request information creation process (step S912). More specifically, the processing unit 32 in the power management server 102 creates request information of the content based on the candidate information selected from the three candidate information created by itself.

Here, since the PV output suppression is not urgent, the processing unit 32 creates the request information based on the received operation information when the operation information is received from the terminal device 171 via the communication unit 21.

More specifically, the processing unit 32 recognizes that the candidate information having an index of 1 is selected by the operator based on the operation information, and from the candidate information having an index of 1, each customer ID and each demand thereof. Acquires the supply suppression power to be allocated to the consumer indicated by the house ID.

Then, the processing unit 32 acquires the device ID corresponding to each acquired consumer ID as the destination of the request information from the management information, and for each device ID, the corresponding destination, the PV suppression period, and the corresponding supply suppression power. Create request information including.

On the other hand, in the case of urgent PV output suppression (YES in step S902), the processing unit 32 selects candidate information from the three candidate information created by itself according to the designated criteria, and uses the selected candidate information as the selected candidate information. Create request information based on the content. Here, the specified criteria are, for example, "expected achievement rate (%)", "expected supply suppression power amount (kW)", "total payment incentive (yen)" and "selected" as shown in FIG. It is a standard using any one of "the number of resources".

The processing unit 32 outputs each created request information to the communication unit 21.

With reference to FIG. 13 again, when the communication unit 21 receives each request information from the processing unit 32, the communication unit 21 transmits each received request information to the consumer device 202 indicated by the destination included in each request information. (Step S328).

Next, when each consumer device 202 receives the request information from the power management server 102, it performs a request information registration process for registering the received request information (step S330).

Next, each consumer device 202 transmits response information indicating whether or not to permit the contents of the request information to the power management server 102 (step S332).

Next, each consumer device 202 periodically transmits the actual value information indicating the actual result of its own PV suppression request to the power management server 102 (step S334).

Next, the processing unit 32 in the power management server 102 determines, for example, whether or not the request for suppressing the power supply to the grid can be fulfilled after the request information is notified by the communication unit 21 (step S336).

More specifically, the processing unit 32 receives response information and actual value information from each consumer device 202 via the communication unit 21, and is a power transmission and distribution business operator based on the response information, actual value information, and suppression information S2. It is determined whether or not adjustment for satisfying the content of the suppression information S2 from the server 141 is necessary.

When the processing unit 32 determines that the above adjustment is necessary (YES in step S336), the processing unit 32 creates new candidate information (step S344). Specifically, the processing unit 32 performs the recommendation processing RP4.

On the other hand, when the processing unit 32 determines that the above adjustment is unnecessary (NO in step S336), the processing unit 32 transmits a permission response signal indicating that the suppression information S2 is permitted to the power transmission and distribution business operator server 141 via the communication unit 21. (Step S338).

Next, the renewable energy business operator server 131 transmits a permission response signal indicating that the suppression information S3 is licensed to the power transmission and distribution business operator server 141 (step S340).

Next, when the power transmission and distribution business server 141 receives the license response signal from the renewable energy business server 131 and the power management server 102, the power transmission and distribution business server 141 performs a recording process for recording each license response signal received (step S342).

Monitor the degree of achievement of output suppression.

Next, when the processing unit 32 determines that the achievement level has not reached the target (YES in step S406), the processing unit 32 performs the recommendation processing RP5 (step S408). Here, since PV output suppression is being executed, the processing unit 32 performs the recommendation processing RP5 without making an inquiry to the operator, for example.

More specifically, the processing unit 32 creates, for example, three candidate information. Specifically, the processing unit 32 creates, for example, candidate information created before the start of PV output suppression, that is, candidate information in which the number of customer IDs included in the pre-start candidate information is increased or decreased, or pre-start candidate information. Candidate information is created by including customer IDs not included in the pre-start candidate information, or candidate information including consumer IDs of consumers belonging to other groups is included in the pre-start candidate information.

Then, the processing unit 32 selects candidate information from the three candidate information created by itself according to, for example, a designated criterion.

The processing unit 32 creates request information for each consumer whose content of PV output suppression is to be changed based on the selected candidate information and management information, and outputs the created request information to the communication unit 21.

Next, when the communication unit 21 receives each request information from the processing unit 32, the communication unit 21 transmits each of the received request information to the consumer device 202 indicated by the destination included in the request information (step S410).

Next, when each consumer device 202 whose content of PV output suppression is changed receives the request information from the power management server 102, the request information registration process for registering the received request information is performed (step S412).

Next, each consumer device 202 whose content of PV output suppression is to be changed executes PV output suppression according to the request information (step S414).

On the other hand, when the processing unit 32 determines that the achievement degree has reached the target (NO in step S406), the recommendation processing RP5 is not performed.

The processing of steps S404 to S414 is repeated, for example, periodically until the PV output suppression is completed.

Next, each consumer device 202 periodically transmits the actual value information to the power management server 102 after the PV output suppression is executed (step S416).

Next, the power management server 102 performs the aggregation process. More specifically, the processing unit 32 in the power management server 102 receives the actual value information from each consumer device 202 via the communication unit 21, and participates in PV output suppression based on the actual value information and the suppression information S2. The actual results of supply restraint power during the PV restraint period of each consumer are tabulated (step S418).

Next, the power management server 102 performs the update process. More specifically, the processing unit 32 updates the performance aggregation information in the storage unit 23 based on the aggregation result (step S420).

Next, the processing unit 32 transmits the actual value information including the total value of the actual supply suppression power in the PV suppression period of each consumer who participated in the PV output suppression to the power transmission and distribution business operator server 141 via the communication unit 21. (Step S422).
