[First Embodiment]
A power consumption management device 10 according to a first embodiment of the present invention will be described below with reference to FIGS. 1 to 7. FIG. As shown in FIG. 1 , the power consumption management device 10 of the present embodiment aims at both ensuring comfort for consumers and improving the DR achievement rate.

DR (demand response) refers to the control of energy resources (power generation equipment, storage equipment, demand equipment) that are connected below the power receiving point of the consumer, by the owner or by a third party, so that the power demand pattern is to change Providing a function equivalent to that of a power plant in this way is called a virtual power plant (VPP).

Here, the power consumption management device 10 is used by the business operator 1 who bundles a plurality of consumers and trades the amount of change in demand by DR with the electric utility company. In this embodiment, an example in which a demand reduction amount is traded as a demand change amount will be described. Note that the amount of increase in demand may be traded as the amount of change in demand, and is not particularly limited.

Operator 1 is also called a DR aggregator. This embodiment will be described by applying it to an example in which there are four consumers. When distinguishing four consumers, they are described as consumer A, consumer B, consumer C, and consumer D. Note that the number of consumers may be greater than or less than four.

Among DR aggregators, those that conduct power transactions with general power transmission and distribution companies and power markets are called parent aggregators. Among DR aggregators, those that directly conclude VPP service contracts with consumers and perform resource control are called resource aggregators.

The power consumption management device 10, as shown in FIG. 1, is an information processing device such as a computer having a CPU (Central Processing Unit), a ROM, a RAM, an input/output interface, and the like. A program stored in a storage device such as the ROM described above cooperates with a CPU, a ROM, a RAM, and an input/output interface to provide at least a DR prediction unit 11, a comfort prediction unit 12, a DR correction unit 13, It functions as an estimation unit 14 , a distribution unit 15 and a storage unit 16 .

The DR prediction unit 11 performs arithmetic processing for obtaining predicted DR information. The predicted DR information is a DR response amount (hereinafter also referred to as “DR amount”), which is a predicted reduction amount of power consumption for each time period after a predetermined DR start time, which is a power consumption reduction start time for a predetermined consumer. ).

The DR prediction unit 11 also calculates the prediction accuracy of the predicted reduction amount of power consumption based on the predicted reduction amount of power consumption and the actual value of the reduction amount. Details of the arithmetic processing in the DR prediction unit 11 will be described later.

The comfort prediction unit 12 performs arithmetic processing for obtaining predicted comfort information. The predicted comfort information includes a predicted value obtained by evaluating the comfort of a predetermined consumer for each time period when the power consumption of the predetermined consumer is reduced based on the predicted DR information.

The comfort prediction unit 12 also calculates the prediction accuracy of the predicted value of comfort, based on the predicted value of comfort and the actual value of comfort. Details of the arithmetic processing in the comfort prediction unit 12 will be described later.

The DR correction unit 13 performs arithmetic processing for obtaining corrected DR information. The corrected DR information is calculated based on the result of comparing the value of comfort in the predicted comfort information for each time slot with respect to the predicted DR information and a predetermined threshold that is the boundary between comfort and discomfort. A modification was made to remove the response amount. The details of the arithmetic processing in the DR correction unit 13 will be described later.

The estimating unit 14 performs arithmetic processing for estimating the responsive capacity and the continuable period based on the corrected DR information. The responsive capacity is the amount of reduction in power consumption that a consumer can respond to, and the continuable period is a period of time during which power consumption can be reduced continuously.

The distribution unit 15 performs arithmetic processing for distributing the reduction amount of power consumption for each time zone to each customer based on the responsive capacity and the continuation possible time. The details of the arithmetic processing in the distribution unit 15 will be described later.

The storage unit 16 stores the predicted amount of reduction in power consumption and the actual value of the amount of reduction in power consumption at the customer. The storage unit 16 also stores predicted values and actual values obtained by evaluating the comfort of the customer.

Next, arithmetic processing in the power consumption management apparatus 10 having the above configuration will be described with reference to FIGS. 2 to 7. FIG. The power consumption management device 10 starts arithmetic processing for managing power consumption described below at a predetermined timing.

In the present embodiment, the power consumption management apparatus 10 manages power consumption on a daily basis, and an example will be described in which arithmetic processing for allocating the DR response amount is performed before the start of a period for managing power consumption. do. The unit of the period in which the power consumption management apparatus 10 manages the power consumption may be a unit of one day, a unit longer than the unit of one day, or a unit shorter than the unit of one day.

When the arithmetic processing for distributing the DR response amount is started, the DR prediction unit 11 of the power consumption management device 10 performs arithmetic processing for obtaining predicted DR information including the DR response amount as shown in FIG. 2 (S10: DR prediction step). Specifically, based on the actual value of the past DR response amount of the predetermined consumer A stored in the storage unit 16, calculation processing for obtaining predicted DR information is performed.

As shown in FIG. 3, the DR prediction unit 11 performs arithmetic processing to obtain the DR response amount for each time period that has passed since the DR start time. Further, arithmetic processing for obtaining the DR response amount is similarly performed for each of a plurality of DR start times. A known calculation method can be used as a specific arithmetic processing method, and is not particularly limited.

In this embodiment, an example in which the time period has a length of 30 minutes will be described. The length of the time period may be in units of 30 minutes, may be in units longer than 30 minutes, or may be in units shorter than 30 minutes.

Also, an example in which the difference between a plurality of DR start times is 30 minutes will be described. Note that the difference between a plurality of DR start times may be 30 minutes, longer than 30 minutes, or shorter than 30 minutes.

When the predicted DR information is obtained, the comfort prediction unit 12 of the power consumption management device 10 performs arithmetic processing to obtain predicted comfort information including predicted values obtained by evaluating comfort, as shown in FIG. 2 (S20: comfort prediction step). The evaluation of comfort is a known evaluation such as PPD (Predicted Percentage of Dissatisfied), SET (Standard new effective temperature), and PMV (Predicted Mean Vote). method can be used. In this embodiment, an example using a PPD will be described.

The comfort prediction unit 12 performs arithmetic processing to obtain a predicted value that evaluates comfort when power consumption is reduced based on the predicted DR information obtained in S10. The predicted value is obtained for each time period that has passed since the DR start time, as shown in FIG. Also, a predicted value is obtained for each of a plurality of DR start times. A known calculation method can be used as a specific calculation method for obtaining the predicted value, and is not particularly limited.

In this embodiment, an example in which the difference between the time zone and the DR start times is 30 minutes will be described. Note that the time zone and the difference between the DR start times may be 30 minutes, longer than 30 minutes, or shorter than 30 minutes.

When the predicted comfort information is obtained, the DR correction unit 13 of the power consumption management device 10 performs arithmetic processing to create corrected DR information obtained by correcting the predicted DR information, as shown in FIG. 2 (S30: DR correction step ).

First, as shown in FIG. 5 , the DR correction unit 13 performs arithmetic processing for comparing a predicted value obtained by evaluating comfort in the predicted comfort information with a predetermined threshold that is the boundary between comfort and discomfort. As a result of the comparison, the time period in which the predicted value falls within the range of -0.5 to 0.5 is judged to be comfortable (○), and the time when the predicted value is outside the range of -0.5 to 0.5 The band is judged as uncomfortable (x).

Here, the example in which the threshold for determining comfort and discomfort is ±0.5 has been applied, but the threshold may be a value other than ±0.5. For example, the business operator 1 using the power consumption management device 10 may arbitrarily set this threshold.

After that, as shown in FIG. 6, the DR correction unit 13 performs arithmetic processing for deleting the DR response amount in the time period determined to be uncomfortable (x) from the predicted DR information. In other words, arithmetic processing is performed to leave only the DR response amount in the time zone determined to be comfortable (o).

After creating the corrected DR information, as shown in FIG. 2, the power consumption management device 10 performs a process of determining whether or not the corrected DR information has been created for all consumers (S40). When it is determined that corrected DR information has not been created for all consumers (in the case of NO), the power consumption management device 10 returns to S10 and repeats the above processing.

If it is determined that the corrected DR information has been created for all consumers (if YES), the estimation unit 14 of the power consumption management device 10 allows the consumers to respond based on the corrected DR information. Arithmetic processing for estimating a responsive capacity, which is the amount of power consumption reduction, and a continuable period, which is a time period during which power consumption can be continuously reduced, is performed (S50: estimation step).

When the responsive capacity and the continuable period are estimated, the distribution unit 15 of the power consumption management device 10 reduces power consumption for each consumer for each time zone based on the responsive capacity and the continuable period. Arithmetic processing for distributing the amount is performed (S60: distribution step).

For example, as shown in FIG. 7, the amount of power consumption reduction is changed and distributed to each of the four consumers for each time period, and the time during which the power consumption continues to be reduced is changed and distributed. It should be noted that a known arithmetic processing can be used as a specific arithmetic processing for distributing the amount of reduction in power consumption, and the specific content of the arithmetic processing is not limited.

According to the power consumption management device 10 configured as described above, it is possible to distribute the amount of power consumption reduction for each time zone to each consumer using the predicted DR information and the predicted comfort information. Therefore, compared to using only one of the predicted DR information and the predicted comfort information, or not using both of them, it is easier to ensure comfort and improve the DR achievement rate at the same time.

Based on the predicted comfort information, corrected DR information is created by excluding the DR response amount in the time period when the consumer feels uncomfortable in the predicted DR information, and based on the corrected DR information, the power consumption of each consumer for each time period is calculated. Reductions can be distributed.

In addition, based on the corrected DR information, in order to estimate the response capacity and the continuation possible period, which is the time period during which power consumption can be reduced continuously, the reduction of power consumption as a group consisting of multiple consumers It makes it easier to achieve your goals.

Note that the distribution unit 15 may distribute the reduction amount of power consumption for each time period based on the prediction accuracy of the predicted reduction amount of power consumption, giving priority to a consumer with high prediction accuracy among a plurality of consumers. .

By distributing the power consumption reduction amount for each time period based on the prediction accuracy of the power consumption prediction reduction amount, it becomes easier to achieve the power consumption reduction target. Specifically, among a plurality of consumers, by distributing the reduction amount of power consumption to a consumer with high prediction accuracy of the predicted reduction amount of power consumption, it becomes easier to achieve the reduction target of power consumption.

Further, the distribution unit 15 may distribute the reduction amount of power consumption for each time period, giving priority to a consumer with high prediction accuracy among a plurality of consumers, based on the prediction accuracy of the predicted value obtained by evaluating the comfort. .

By distributing the amount of power consumption reduction for each time period based on the prediction accuracy of the predicted value obtained by evaluating comfort, it becomes easier to achieve the power consumption reduction target. Specifically, among multiple consumers, by distributing the amount of power consumption reduction to consumers with high prediction accuracy in the prediction value that evaluates comfort, it becomes easier to achieve the power consumption reduction target. .

By distributing the amount of reduction in power consumption to all consumers who can distribute the amount of reduction in power consumption, the impact of prediction errors in the amount of predicted reduction in power consumption of individual consumers is smoothed out, and power consumption can be predicted. The prediction error of the total reduction amount is small. This makes it easier to achieve the power consumption reduction target.

[Second embodiment]
Next, a second embodiment of the present invention will be described with reference to FIGS. 8 to 26. FIG. The basic configuration of the power consumption management apparatus of this embodiment is the same as that of the first embodiment, but differs from the first embodiment in that a determination unit is provided. Therefore, in the present embodiment, processing in the determination unit and processing related to the processing will be described using FIGS. 8 to 26, and description of similar processing in the power consumption management apparatus of the first embodiment will be omitted. .

As shown in FIG. 8, the power consumption management device 110 of this embodiment is an information processing device such as a computer having a CPU (Central Processing Unit), a ROM, a RAM, an input/output interface, and the like. A program stored in a storage device such as the above-described ROM cooperates with a CPU, a ROM, a RAM, and an input/output interface to at least a DR prediction unit 111, a comfort prediction unit 112, a distribution unit 115, and a storage unit. It functions as the unit 16 and the determination unit 117 .

The DR prediction unit 111 performs arithmetic processing for obtaining predicted DR information at a plurality of levels (hereinafter also referred to as “DR levels”) with different degrees of power consumption reduction. , DR level n, . . . DR level n_max (n is a natural number, n_max is the maximum DR level) is written as In this embodiment, an example in which n_max is 4 will be described.

Specifically, for example, if the set temperature relaxation range for air conditioning is 1° C., it corresponds to DR level 1, and if it is 2° C., it corresponds to DR level 2. Note that the correspondence relationship between the amount of power consumption reduction and each DR level, the range of the amount of power consumption reduction at each DR level, and the like are not limited to the above examples, and may be set arbitrarily.

In addition, the DR prediction unit 111 also calculates the prediction accuracy of the predicted reduction amount of power consumption based on the predicted reduction amount of power consumption and the actual value of the reduction amount at a plurality of levels with different degrees of reduction in power consumption. . The details of the arithmetic processing in DR prediction section 111 will be described later.

The comfort prediction unit 112 performs arithmetic processing for obtaining predicted comfort information based on predicted DR information at a plurality of DR levels. The comfort prediction unit 112 also calculates the prediction accuracy of the predicted value obtained by evaluating the comfort based on the predicted comfort information and actual values at a plurality of DR levels. The details of the arithmetic processing in comfort prediction section 112 will be described later.

Distributing unit 115 calculates consumption for each consumer for each time zone based on the DR response amount included in the predicted DR information and the predicted value obtained by evaluating the comfort included in the predicted comfort information at a plurality of DR levels. It performs arithmetic processing for distributing the amount of power reduction. Details of the arithmetic processing in the distribution unit 115 will be described later.

The storage unit 16 stores priority information indicating whether the consumer gives priority to reduction of power consumption or comfort. Further, similarly to the storage unit 16 of the first embodiment, the predicted reduction amount and actual reduction amount of power consumption at the customer, and the predicted value and actual value obtained by evaluating comfort at the customer are stored. But also.

The determination unit 117 performs arithmetic processing for determining whether or not the DR response amount in the predicted DR information is within a predetermined allowable range of the response amount for each time slot. Further, calculation processing is performed for each time period to determine whether or not the value obtained by evaluating comfort in the predicted comfort information is within a predetermined allowable range of comfort.

Next, arithmetic processing in the power consumption management device 110 having the above configuration will be described with reference to FIGS. 9 to 26. FIG. The power consumption management device 110 starts arithmetic processing for managing power consumption described below at a predetermined timing.

When the arithmetic processing for managing power consumption is started, power consumption management device 110, as shown in FIG. Arithmetic processing is performed to determine whether the priority information to be displayed is stored (hereinafter also referred to as “labeling”) (S101).

When it is determined that the consumer is not labeled, the power consumption management device 110 performs arithmetic processing to label the consumer (S200). When the labeling arithmetic processing is started, the power consumption management device 110 determines that the rate dy/dx at which the comfort decreases when the DR amount is increased is equal to or less than a predetermined threshold value α, as shown in FIG. Arithmetic processing for determining whether or not is performed (S201). Note that the threshold α is a value that can be arbitrarily set and changed by the operator of the power consumption management device 110 or the consumer.

As shown in FIG. 12, the ratio dy/dx at which the comfort decreases when the DR amount is increased is plotted with the DR amount on the horizontal axis (X-axis) and the comfort on the vertical axis (Y-axis). It means the slope of the graph in the case.

Here, when the DR amount increases, it moves to the positive side (right side) of the X axis, and when the comfort level increases, it moves to the positive side (upper side) of the Y axis. This embodiment will be described by applying it to the case where dy/dx takes a negative value. In other words, the description will be made by applying to an example in which the graph in FIG. 12 is downward sloping.

When it is determined that dy/dx is equal to or less than the threshold value α in the determination process of S201 (in the case of YES), the power consumption management device 110 performs a process of labeling the consumer with priority given to comfort. (S202).

A case where dy/dx is equal to or less than the threshold value α is considered to be a case where the rate of decrease in comfort when the DR amount is increased is greater than the rate that can be tolerated by consumers and the like. In this case, labeling that gives priority to comfort is performed so that comfort is easily controlled within an allowable range for consumers and the like.

When it is determined that dy/dx is not equal to or less than the threshold value α in the determination process of S201 (in the case of NO), the power consumption management device 110 performs the process of labeling the consumer with priority given to the DR amount. (S203).

A case where dy/dx is not equal to or less than the threshold value α (exceeds the threshold value α) is considered to be a case where the rate of decrease in comfort when the DR amount is increased is smaller than the rate that the consumer can tolerate. be done. In this case, comfort is likely to fall within a range acceptable by consumers and others, so labeling that gives priority to the DR amount is performed so that control that facilitates ensuring the DR amount is performed.

Note that the power consumption management device 110 may perform the arithmetic processing shown in FIG. 13 instead of the arithmetic processing shown in FIG. 11 . In other words, the power consumption management device 110 performs arithmetic processing to determine whether or not there is a complaint from the consumer during DR implementation (S211). Specifically, a process of determining whether or not the storage unit 16 stores a complaint associated with the consumer is performed.

Examples of complaints include those complaining that comfort is impaired during DR implementation, and those complaining about a decrease in the set temperature of air conditioning. When there is a complaint, it is stored in the storage unit 16.例文帳に追加

The storage unit 16 associates and stores the complaint with information identifying the consumer who made the complaint. Note that the storage unit 16 may also store the date and time of the complaint, the content of the complaint, and the like.

If it is determined that there is a complaint in the determination process of S211 (YES), the power consumption management device 110 performs a process of labeling the consumer with priority given to comfort (S202).

If it is determined that there has been a complaint, it is highly likely that the customer will complain again if DR control is performed. Therefore, labeling that gives priority to comfort is performed so that control that reduces the possibility of complaints is performed.

When it is determined that there is no complaint in the determination process of S211 (in the case of NO), the power consumption management device 110 performs a process of labeling the consumer with priority given to the DR amount (S203).

If it is determined that there are no complaints, it is considered unlikely that the customer will complain again even if DR control is performed. Therefore, labeling that prioritizes the DR amount is performed so that control that facilitates securing the DR amount is performed.

Furthermore, the power consumption management device 110 may perform the arithmetic processing shown in FIG. 14 . In other words, the power consumption management device 110 performs arithmetic processing to determine whether or not the consumer places importance on comfort (S221). Specifically, processing is performed to determine whether or not the storage unit 16 stores the consumer and the information that emphasizes comfort in association with each other.

Examples of information emphasizing comfort include a type representing the type of business of the customer. For example, it is possible to know that the customer is a medical institution based on the type. By predetermining that the medical institution attaches importance to comfort, it is possible to determine that the consumer, who is the medical institution, attaches importance to comfort.

Note that the number of types representing the type of business of the consumer can be arbitrarily set by the administrator of the power consumption management device 110 as to the range included in one type. In addition, the above-described administrator can arbitrarily set the type of industry and type for which comfort is emphasized.

Also, the information that emphasizes comfort may be set based on a report from the consumer. In other words, it may be determined that a consumer who has declared that comfort is important is that comfort is important. In addition, it may be determined that a consumer who declares that comfort is not important is not concerned with comfort.

When it is determined that comfort is emphasized in the determination process of S221 (in the case of YES), the power consumption management device 110 performs a process of labeling the consumer with priority given to comfort. (S202).

When it is determined that comfort is not emphasized in the determination process of S221 (in the case of NO), the power consumption management device 110 performs a process of labeling the consumer with priority given to the DR amount. (S203).

Note that power consumption management device 110 may perform only one of the arithmetic processes described with reference to FIGS. you can go

After performing the arithmetic processing for labeling the consumer, the power consumption management device 110 returns to FIG. 9 and performs the arithmetic processing for predicting the DR potential. Alternatively, if it is determined in the arithmetic processing of S101 that the consumer is labeled (determined as YES), the power consumption management device 110 performs arithmetic processing for predicting the DR potential (S300). Here, the DR potential includes predicted DR information and predicted comfort information at each DR level n.

When the arithmetic processing for predicting the DR potential is started, the power consumption management device 110 performs arithmetic processing for setting the DR level n to the DR level 1 as shown in FIG. 15 (S301). In the present embodiment, an example will be described in which arithmetic processing for storing 1 in the variable n representing the DR level is performed.

The DR prediction unit 111 of the power consumption management device 110 performs arithmetic processing to obtain predicted DR information including the DR response amount at the DR level n (S302: DR prediction step). Specifically, the DR prediction unit 111 performs arithmetic processing to obtain predicted DR information based on the actual value of the past DR response amount of the predetermined consumer A stored in the storage unit 16 . The arithmetic processing for obtaining predicted DR information in S302 is the same as the arithmetic processing in the DR prediction unit 11 of the first embodiment.

When the predicted DR information is obtained, the comfort prediction unit 112 of the power consumption management device 110 performs arithmetic processing to obtain the predicted comfort information including the predicted value obtained by evaluating the comfort at the DR level n (S303: comfort prediction step). The arithmetic processing for obtaining predicted comfort information performed by the comfort prediction unit 112 in S303 is the same as the arithmetic processing in the comfort prediction unit 12 of the first embodiment.

When the predicted comfort information is obtained, power consumption management device 110 performs arithmetic processing to determine whether or not the value stored in variable n is equal to n_max, which is the maximum value of variable n (S304). . In other words, an arithmetic process is performed to determine whether or not the DR level n has reached the maximum level.

If it is determined that the value stored in variable n is not n_max (is not equal to n_max) (NO), power consumption management device 110 adds 1 to the value stored in variable n. Arithmetic processing is performed to perform computation and store the computation result in a variable n (S305).

When 1 is added to the variable n, the power consumption management device 110 returns to S302 and repeats the above-described arithmetic processing. In this case, since 1 is added to the variable n, arithmetic processing is performed at the DR level one level higher.

When it is determined in the determination processing of S304 that the value stored in the variable n is equal to n_max (in the case of YES), the arithmetic processing in the power consumption management device 110 returns to FIG. In other words, when the consumer obtains predicted DR information and predicted comfort information for each level from DR level 1 to DR level n_max, the arithmetic processing in power consumption management device 110 returns to FIG.

As shown in FIG. 9, the power consumption management device 110 performs arithmetic processing for determining whether or not the DR potential has been predicted for all consumers (S102). A known determination process can be used as the specific calculation process in S102, and is not particularly limited.

When it is determined that the DR potential is not predicted for all consumers (in the case of NO), the power consumption management device 110 returns to S101 and repeats the above arithmetic processing. Note that when returning to S101, it is preferable to select a customer different from the customer who has already been subjected to the arithmetic processing of S101.

When it is determined that the DR potential is predicted for all consumers (in the case of YES), the determining unit 117 of the power consumption management device 110 performs arithmetic processing to determine whether DR can be implemented ( S103). Arithmetic processing for determination in the determination unit 117 is performed for each of all consumers. In addition, arithmetic processing for determination is performed for each time period that has elapsed from the DR start time of each consumer, and similar arithmetic processing for determination is performed for each of a plurality of DR start times.

In the arithmetic processing for determination, as shown in FIG. 16, the allowable range of the response amount and the allowable range of comfort are referred to. Note that the horizontal axis in FIG. 16 represents the DR level, the right vertical axis represents the DR amount, and the left vertical axis represents the comfort evaluation value. The vertical axis on the right side indicates that the DR amount increases as it goes upward, and the vertical axis on the left side indicates that the comfort level increases as it goes upward. Further, the solid-line graph D represents the DR amount, and the dotted-line graph C represents comfort.

The allowable range of response amounts is a range of DR response amounts that at least satisfies the DR request amount. The DR request amount is the DR response amount requested by the operator 1 . An example can be given in which the value is determined according to a request from the business operator 1 . The allowable range of comfort is such that the consumer feels comfortable if the comfort is within the range, and feels uncomfortable if the comfort is outside the range. As the allowable range of comfort, there is an example of using a range agreed upon with the customer.

In the example shown in FIG. 16, in the case of a predetermined consumer, at DR level 1, the DR amount is outside the allowable range of the response amount, in other words, it is less than the DR request amount (indicated by x in the figure). The comfort is within the allowable range of comfort (indicated by ○ in the figure). At DR level 2, the DR amount is within the permissible range of the response amount, in other words, it is greater than or equal to the DR required amount (indicated by ◯ in the figure), and the comfort is within the permissible range of comfort. At DR level 3 and DR level 4, the DR amount is within the allowable range of the response amount, and the comfort is outside the allowable range of comfort (indicated by x in the figure).

The determination unit 117 of the power consumption management apparatus 110 further performs arithmetic processing for determining whether DR can be implemented based on the table shown in FIG. 17 . That is, whether or not DR is to be implemented is determined based on whether the DR amount is within or outside the allowable range of the response amount and whether the comfort is within or outside the allowable range of comfort at each DR level.

The determination unit 117 of the power consumption management device 110 determines that DR can be implemented only when the DR amount is within the allowable range of the response amount and the comfort is within the allowable range of comfort. Further, the power consumption management device 110 also determines a specific DR amount (kW value) when it is determined that DR can be performed.

If the other DR amount is within the allowable range of the response amount and the comfort is outside the allowable range of comfort, if the DR amount is outside the allowable range of the response amount and the comfort is within the allowable range of comfort, and the DR amount is out of the permissible range of the response amount and the comfort is out of the permissible range of the comfort, it is determined that DR implementation is not possible.

As shown in FIG. 18 , the determination result of whether or not DR can be implemented by the determination unit 117 of the power consumption management apparatus 110 is stored in association with the consumer, the DR start time, and the time period after the DR start time. Stored in unit 16 .

When it is determined whether DR can be implemented, the distribution unit 115 of the power consumption management device 110 performs arithmetic processing to distribute the DR amount to each consumer (S104). The distribution calculation processing by the distribution unit 115 in S104 is the same as the distribution calculation processing in S60 in the first embodiment, except that the DR level with the largest DR amount is selected from among the DR levels determined to be DR executable. (See FIGS. 2 and 7, etc.).

When the DR amount is distributed, the power consumption management device 110 performs a process of instructing the corresponding consumer with the distributed DR amount (S105). For example, the consumer A is instructed to reduce power consumption by 10 kW from 10:00 to 10:30 and to reduce power consumption by 15 kW from 10:30 to 11:00.

In addition, the consumer B is instructed to reduce power consumption by 15 kW from 13:30 to 14:00 and to reduce power consumption by 10 kW from 14:00 to 14:30. Here, although the DR amount distributed to each consumer is instructed, control for reducing power consumption in the consumer is not executed.

When the DR amount is commanded, as shown in FIG. 10, the DR prediction unit 111 of the power consumption management device 110 performs arithmetic processing for re-predicting the DR potential for any one consumer (S400). Since the re-prediction of the DR potential by the DR prediction unit 111 is the same arithmetic processing as the prediction of the DR potential in S300, FIG. do.

After the arithmetic processing for re-predicting the DR potential is performed, returning to FIG. 10, the power consumption management device 110 performs the arithmetic processing for determining whether or not the DR potential has been re-predicted for all consumers (S106). ).

If it is determined that the DR potential has not been re-predicted for all consumers (NO), the power consumption management device 110 returns to S400 and repeats the above-described arithmetic processing. It should be noted that, when returning to S400, it is preferable to select a customer different from the customer who has already been subjected to the arithmetic processing of S400.

When it is determined that the DR potential is re-predicted for all consumers (YES), the power consumption management device 110 performs arithmetic processing to determine whether DR can be implemented (S107).

Arithmetic processing for determination is performed for each of all consumers. In addition, arithmetic processing for determination is performed for each time period that has elapsed from the DR start time of each consumer, and similar arithmetic processing for determination is performed for each of a plurality of DR start times.

Here, description will be made based on the example shown in FIG. In the example shown in FIG. 20, at DR level 1 and DR level 2, the DR amount is outside the allowable range of the response amount (indicated by x in the figure), and the comfort is within the allowable range of comfort. (Indicated by ○ in the figure). At DR level 3 and DR level 4, the DR amount is within the allowable range of the response amount (indicated by ○ in the figure), and the comfort is outside the allowable range of comfort (indicated by × in the figure). it's shown.). The example shown in FIG. 20 differs from the example shown in FIG. 16 in that there is no DR level at which the DR amount is within the allowable range of the response amount and the comfort is within the allowable range of comfort.

The determination unit 117 of the power consumption management apparatus 110 further performs arithmetic processing for determining whether DR can be implemented based on the table shown in FIG. 21 . The table shown in FIG. 21 shows a case where the DR amount is within the allowable range of the response amount and the comfort is outside the allowable range of the comfort, and when the DR amount is outside the allowable range of the response amount and the comfort is the comfort level. , is different from the table shown in FIG. That is, in the table shown in FIG. 17, DR implementation is prohibited, whereas in the table shown in FIG. 21, it is determined according to priority.

In addition, when the DR amount is within the allowable range of the response amount and the comfort is within the allowable range of comfort, and when the DR amount is outside the allowable range of the response amount and the comfort is outside the allowable range of comfort The determination of whether to implement DR in the case is the same as the determination of whether to perform DR in S103.

When the DR amount is within the allowable range of the response amount and the comfort is outside the allowable range of comfort, and when the DR amount is outside the allowable range of the response amount and the comfort is within the allowable range of comfort The contents of the approval/disapproval determination will be described with reference to FIG. 22 .

FIG. 22 shows the determination result of whether or not the DR amount at each DR level is within the allowable range of the response amount, the determination result of whether or not the comfort is within the allowable range of comfort, and the labeling of the consumer. The results of determining whether or not to implement DR when priority is given and the results of determining whether or not DR can be performed when the customer's labeling is comfort priority are shown. Note that the description in parentheses in the DR amount determination results is the value of the DR amount at each DR level.

Here, the decision as to whether or not DR can be implemented when DR is prioritized is a decision that prioritizes securing the DR amount. Therefore, in order to ensure the DR amount, a determination is made to allow the comfort to fall outside the allowable comfort range. In the case of FIG. 22, it is determined that DR implementation is possible (indicated by ◯ in the drawing) at DR levels 1 to 4. FIG.

Further, the determination of DR execution propriety when comfort is prioritized is a determination that prioritizes comfort being within the allowable range of comfort. Therefore, a determination is made to allow the DR amount to fall outside the allowable range of the response amount. In the case of FIG. 22, it is determined that DR can be performed at DR levels 1 and 2, and that DR cannot be performed at DR levels 3 and 4 (indicated by x in the figure). be.

When the DR demanded amount is 10 kW, when the consumer's labeling is DR priority, the DR amount exceeds the DR demanded amount (10 kW) and is the largest DR demanded amount among the DR levels at which DR implementation is determined to be possible. DR level 3, which is close to , is selected as the DR level at which DR can be performed.

Further, when the consumer's labeling is comfort priority, the DR level 2 whose DR amount is closest to the DR demanded amount (10 kW) is the DR level at which DR can be performed among the DR levels determined to be capable of DR implementation. is selected as

(S501).

The power consumption management device according to claim 1, wherein said comfort prediction unit obtains said predicted comfort information based on said predicted DR information at said plurality of levels. determining whether the DR response amount in the predicted DR information is within an allowable range of a predetermined response amount for each of the time slots;
A determination unit is further provided for determining whether the value obtained by evaluating the comfort in the predicted comfort information for each time period is within a predetermined allowable range of comfort,
Instead of the predicted DR information and the predicted comfort information, the distribution unit provides a determination result as to whether the DR response amount is within an allowable range of the predetermined response amount and a value obtained by evaluating the comfort. 6. The power consumption management according to claim 5 , wherein the amount of change in power consumption for each time slot is distributed to each customer based on the determination result as to whether or not the comfort is within the predetermined allowable range of comfort. Device. A storage unit is further provided for storing priority information indicating which of the change in power consumption and the comfort is given priority by the consumer,
The distribution unit
When it is determined that the DR response amount at the level is within the allowable range of the predetermined response amount and the value obtained by evaluating the comfort is within the predetermined allowable range of comfort, the change in power consumption do the distribution of the amount,
The DR response amount at the level is within the allowable range of the predetermined response amount, and the value obtained by evaluating the comfort is outside the predetermined allowable range of comfort, and the DR response amount at the level is within the predetermined allowable range. If it is determined that the response amount is out of the permissible range and the value obtained by evaluating the comfort is within the predetermined permissible range of comfort, the consumption based on the priority information stored in the storage unit Distribute the amount of change in power,
When it is determined that the DR response amount at the level is outside the allowable range of the predetermined response amount and the value obtained by evaluating the comfort is outside the allowable range of the predetermined comfort, the change in the power consumption 7. The power consumption management device according to claim 6 , wherein no amount is distributed. a DR prediction step of obtaining predicted DR information including a DR response amount that is a predicted change amount of power consumption for each time period that has passed from a predetermined DR start time that is a change start time of power consumption for a predetermined consumer;
comfort for obtaining predicted comfort information including a predicted value obtained by evaluating the comfort of the predetermined consumer for each of the time periods when the power consumption of the predetermined consumer is changed based on the predicted DR information; a sex prediction step;
a distribution step of distributing an amount of change in power consumption for each time slot to each customer, using the predicted DR information and the predicted comfort information;
has
For the predicted DR information, the value obtained by evaluating the comfort in the predicted comfort information for each of the time periods is compared with a predetermined threshold that is the boundary between comfort and discomfort, and the comfort is evaluated. a DR correction step of creating corrected DR information corrected to delete the DR response amount in the time period in which the value obtained is the value on the uncomfortable side;
An estimation step of estimating, based on the corrected DR information, a responsive capacity, which is the amount of change in power consumption that the consumer can respond to, and a continuable period, which is a time period during which the power consumption can continue to change. and,
further having
In the distributing step, instead of the predicted DR information and the predicted comfort information, based on the responsive capacity and the continuable period, the amount of change in power consumption for each time period is distributed to each customer.
A power consumption management method characterized by:
