Description

[Technical field]

[0001] The present disclosure relates to a selection device, a demand response system, and a selection method. [Background technology]

[0002] When a demand response request (request to suppress received power) is received from a general electricity transmission and distribution business operator, the demand response system (hereinafter, demand response may be referred to as DR) notifies the edge device of each consumer of the control amount that satisfies the requested suppression amount of received power (referred to as the requested amount), and has the consumer suppress the received power according to the control amount, thereby attempting to fulfill the DR request from the general electricity transmission and distribution business operator. Furthermore, after starting power suppression based on the DR request, the DR system monitors the actual suppression status of received power of each consumer, and if it predicts a shortage or a large excess, it changes the control amount notified to each consumer individually (hereinafter, referred to as the adjustment power effective utilization method), thereby suppressing received power to the right level.

[0003] However, even if consumers have the capacity to participate in the effective use of balancing capacity method, they may not want to be included in the application of the method due to reasons such as the condition of the equipment, construction plans or operation plans of the equipment, or contractual relationships with other electricity markets. Also, even if consumers are willing to cooperate with the effective use of balancing capacity method, they may not have the capacity to cooperate with the effective use of balancing capacity, or their equipment may have an abnormality or malfunction, making it inappropriate for them to be included in the application.

[0004] Patent Literature 1 discloses a method for preferentially selecting consumers who are likely to succeed in implementing DR, in order to address the issue that consumers may select consumers who are likely to fail to implement DR when making selections with a focus on fairness among consumers. However, Patent Literature 1 does not disclose a method for selecting consumers to which the adjustment capacity effective utilization method is applied. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] JP 2018-5314 A Summary of the Invention [Problem to be solved by the invention]

[0006] To provide a method for selecting consumers to which an adjustment capacity effective utilization method, which aims to achieve the requested amount by adjusting the amount of power suppression borne by each consumer, is applied when it is predicted that the requested amount will not be achieved after power suppression has begun based on a DR request.

[0007] The present disclosure provides a selection device, a demand response system, and a selection method that can solve the above problems. [Means for solving the problem]

[0008] The selection device according to the present disclosure includes a determination unit that determines which consumers should apply an adjustment capacity effective utilization method, which is a method for achieving the requested amount of a demand response request by adjusting the amount of power suppression borne by the consumer when the requested amount cannot be achieved, and which consumers should not apply the method.

[0009] The demand response system of the present disclosure includes the above-mentioned selection device, a management device that adjusts the requested amount to a consumer for which it has been determined that the adjustment power effective utilization method should be applied so that the requested amount can be achieved and notifies an edge device of the consumer of the adjusted requested amount, and an edge device that controls the equipment of the consumer so as to perform power suppression indicated by the requested amount.

[0010] In the selection method disclosed herein, when the requested amount of a demand response request cannot be achieved, a determination is made as to which consumers should apply an effective adjustment capacity utilization method, which is a method of achieving the requested amount by adjusting the amount of power suppression borne by the consumer, and which consumers should not apply the method. Effect of the Invention

[0011] According to the selection device, demand response system, and selection method of the present disclosure, it is possible to select consumers to which the adjustment capacity effective utilization method is applied. [Brief description of the drawings]

[Figure 2A] FIG. 11 is a first diagram for explaining a response possibility determination according to the second embodiment. [Figure 2B] FIG. 11 is a first diagram for explaining a response possibility determination according to the second embodiment. [Diagram 3] 4 is a flowchart illustrating an example of a consumer selection process according to the embodiment. [Figure 4] FIG. 2 illustrates an example of a hardware configuration of a selection system according to an embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] <Embodiment> Hereinafter, a method for selecting consumers to which the adjustment power effective utilization method of the present disclosure is applied will be described with reference to Figs. (composition) FIG. 1 is a diagram illustrating an example of a selection system according to an embodiment. The selection system 100 includes a general electricity transmission and distribution company system 1, a demand response system 2 (hereinafter referred to as the DR system 2) managed by an aggregator that adjusts the electricity supply and demand of consumers to satisfy DR requests from the general electricity transmission and distribution company system 1, and consumers 3A to 3N managed by the aggregator. The general electricity transmission and distribution company system 1 transmits a DR request signal. The DR request signal includes information such as a DR request amount indicating the extent to which the received power should be restricted and a time period during which the received power restriction is to be performed. The DR system 2 includes a DR system server 20 and DR system edge devices 23A to 23N (the DR system edge devices 23B to 23N are not shown). The DR system server 20 includes an adjustment power effective utilization calculation function 21 and adjustment power effective utilization determination functions 22A to 22N. The adjustment capacity effective utilization calculation function 21 adjusts the amount of power suppression borne by the consumer 3A, etc., to which the adjustment capacity effective utilization method is applied, when it is predicted that the DR request amount will not be achieved after the start of power suppression control based on the DR request (hereinafter, described as after DR implementation). For example, it is assumed that the consumer 3A has a contract with the aggregator under which the consumer 3A can suppress power by 100 kW when making a DR request, and the consumer 3A has already suppressed power by 70 kW as power suppression based on the DR request. In this case, for example, the adjustment capacity effective utilization calculation function 21 adjusts the amount of power suppression borne by the consumer 3A (for example, changes the requested amount to the consumer 3A from 70 kW to 100 kW) using the surplus capacity (remaining 30 kW) of the consumer 3A. The requested amount is the amount of power suppression that each consumer should bear in response to the DR request. In this way, the DR request amount is achieved by adjusting the excess or shortfall of the DR request amount after DR implementation. After DR is implemented, the actual extent of power suppression can be determined by tallying up the power usage status transmitted from the DR system edge device 23A etc. installed in each consumer 3A etc. The adjustment capacity effective utilization calculation function 21 determines whether the DR request amount has been achieved based on the DR request amount from the general power transmission and distribution company system 1 and the power usage status of the consumers 3A to 3N, and calculates the excess or shortfall with respect to the DR request amount if it has not been achieved. The adjustment capacity effective utilization calculation function 21 allocates the calculated excess or shortfall to the consumers 3A etc. to which the adjustment capacity effective utilization method is applied, and calculates the adjusted request amount for each consumer. The adjustment capacity effective utilization calculation function 21 notifies the adjusted request amount to the DR system edge devices 23A to 23N installed in each consumer through the adjustment capacity effective utilization determination functions 22A to 22N.

[0014] The adjustment capacity effective utilization determination functions 22A to 22N are provided for each consumer, and determine whether the corresponding consumer is an application target of the adjustment capacity effective utilization method. That is, the adjustment capacity effective utilization determination function 22A determines whether the consumer 3A is an application target of the adjustment capacity effective utilization method, and the adjustment capacity effective utilization determination function 22B determines whether the consumer 3B is an application target of the adjustment capacity effective utilization method. The same applies to the adjustment capacity effective utilization determination functions 22C to 22N. Conventionally, the adjustment capacity effective utilization method has been applied or not applied uniformly to the consumers 3A to 3N under the DR system 2. However, if this is done, even if there are consumers who do not want to be included in the control to which the adjustment capacity effective utilization method is applied (for example, if the consumer 3A is a factory and wants to use all the capacity of his / her power generation equipment for production activities at the factory, the consumer 3A does not want the adjustment capacity effective utilization method to be applied), these consumers will be forced to make effective use of adjustment capacity. On the other hand, if the non-application setting is made uniformly, it is not possible to respond to cases where it is predicted that the DR request amount will not be achieved, and it becomes difficult to avoid the occurrence of penalty costs associated with demand response failure. Therefore, in this embodiment, the DR system 2 is provided with a function unit (adjustment capacity effective utilization determination function 22A to 22N) that determines whether or not the adjustment capacity effective utilization method is applied to each of the consumers 3A to 3N. For example, the adjustment capacity effective utilization determination function 22A determines whether or not the adjustment capacity effective utilization method is applied to the consumer 3A, and notifies the adjustment capacity effective utilization calculation function 21 of the determination result. If the adjustment capacity effective utilization method is applied to the consumer 3A, the adjustment capacity effective utilization determination function 22A receives the adjusted request amount from the adjustment capacity effective utilization calculation function 21 and notifies the adjusted request amount to the DR system edge device 23A. The same applies to the adjustment capacity effective utilization determination functions 22B to 22N.

[0015] The DR system edge device 23A is a computer terminal such as a server installed in the consumer 3A. The consumer 3A includes a load 3A1 configured with equipment with limited control, a power generation facility 3A2 configured with equipment with limited control such as PV (photovoltaic power generation), a load 3A3 configured with equipment that is easy to control, a power generation facility 3A4 configured with equipment that is easy to control such as a turbine and an engine, and a chargeable and dischargeable power storage facility 3A5. When a DR request is received, the consumer 3A responds to the DR request by suppressing the power consumption of the load 3A3 that is easy to control, generating power with the power generation facility 3A4 that is easy to control, and discharging from the power storage facility 3A5. For example, when a request for power suppression of 100 kW (request amount 100 kW) is received, the consumer 3A responds to the power suppression of 100 kW by suppressing the power consumption of the load 3A3 by 10 kW, generating 90 kW of power by generating power with the power generation facility 3A4 and discharging from the power storage facility 3A5. In order to perform such power suppression, the DR system edge device 23A determines the distribution of the power consumption to be suppressed by the load 3A3, the power to be generated by the power generation facility 3A4, and the power to be discharged by the power storage facility 3A5. Then, the DR system edge device 23A transmits control information to the controller 3A10 controlling the load 3A3, for example, instructing the suppression of 10 kW according to the determined distribution. The controller 3A10 controls the load 3A3 so that the power consumption by the load 3A3 is suppressed by 10 kW based on this instruction information. In addition, the controller 3A10 transmits measurement information such as the power used by the load 3A3 to the DR system edge device 23A. Similarly, the DR system edge device 23A transmits control information to the controller 3A11 controlling the power generation facility 3A4 to prompt the power generation of a predetermined amount of 90 kW. The controller 3A11 controls the power generation facility 3A4 so that the power generation facility 3A4 generates a predetermined amount of power based on this instruction information. In addition, the controller 3A11 transmits measurement information such as power generated by the power generation facility 3A4 to the DR system edge device 23A. The DR system edge device 23A transmits control information to the controller 3A12 that controls the power storage facility 3A5 to prompt the power storage facility 3A5 to discharge a predetermined amount of the 90 kW. The controller 3A12 controls the power storage facility 3A5 based on this instruction information so that the power storage facility 3A5 discharges the predetermined amount.The controller 3A12 also transmits metering information such as power discharged from the power storage facility 3A5 to the DR system edge device 23A. The above also applies when the adjustment power effective utilization method is applied after the DR request and the requested amount is adjusted. In addition, the meter 3A7 installed near the power receiving point 3A6 of the power system transmits metering information such as measured power to the DR system edge device 23A. The meter 3A8 that measures the power supplied to the load 3A1 transmits metering information such as measured power to the DR system edge device 23A. The meter 3A9 that measures the power generated by the power generation facility 3A2 transmits metering information such as measured power to the DR system edge device 23A. In this way, the DR system edge device 23A collects information on the power consumed or supplied (such as power generation or discharge) by various facilities in the consumer 3A and the status of the various facilities, for example, whether an abnormality or failure has occurred, and if so, information such as an error code, and transmits the information to the adjustment power effective utilization determination function 22A on the server side. In addition, the DR system edge device 23A has a function of determining how to respond to the amount of power suppression (request amount) that the consumer 3A should bear, which is calculated by the DR system server 20 based on a DR request from a general electricity transmission and distribution company, and controlling the load 3A3, the power generation equipment 3A4, and the storage equipment 3A5.

[0016] Furthermore, the DR system edge device 23A includes an adjustment capacity effective utilization application / non-application request generation function 231A. The adjustment capacity effective utilization application / non-application request generation function 231A accepts a setting of "application", "non-application", "automatic determination", or "server-side automatic determination" from, for example, a user of the consumer 3A regarding the application of the adjustment capacity effective utilization method, and transmits an application request or a non-application request to the adjustment capacity effective utilization determination function 22A according to this setting. For example, when "application" is set, the adjustment capacity effective utilization application / non-application request generation function 231A transmits an "application request", and when "non-application" is set, it transmits a "non-application request". When "automatic determination" is set, the adjustment capacity effective utilization application / non-application request generation function 231A determines whether or not to apply the adjustment capacity effective utilization method by itself, and transmits an "application request" or a "non-application request" based on the determination result. When "server-side automatic determination" is set, the server-side adjustment capacity effective utilization determination function 22A determines whether or not to apply the adjustment capacity effective utilization method to the consumer 3A. In this case, the adjustment capacity effective utilization application / non-application request generation function 231A transmits a "judgment request" to the adjustment capacity effective utilization judgment function 22A.

[0017] The consumers 3B to 3N are also provided with devices (DR system edge devices 23B to 23N) similar to the DR system edge device 23A. The DR system edge devices 23B to 23N each have a functional unit similar to the adjustment capacity effective utilization application / non-application request generation function 231A.

[0018] Next, referring to FIG. 2A and FIG. 2B, a method of determining whether or not to apply the adjustment capacity effective utilization application / non-application request generation function 231A when "automatic determination" is set will be described. The DR system edge device 23A can grasp the operation status of the load 3A3, the power generation equipment 3A4, and the power storage equipment 3A5 from the measurement information transmitted from the controllers 3A10, 3A11, and 3A12, respectively, and can grasp the spare capacity of these equipment. For example, if the maximum output of the power generation equipment 3A4 is 1 MW and the actual output is 0.7 MW, there is a spare capacity of 0.3 MW, and a maximum of 0.3 MW can be used to respond to a DR request (including effective utilization of adjustment capacity). The power that can be used for DR implementation, such as the spare capacity at this time, is called a contribution available amount. The adjustment capacity effective utilization application / non-application request generation function 231A calculates the contribution available amount for each predetermined unit time from the operation record of the power generation equipment 3A4, etc. for the past one year, for example. Also, for the load 3A3, the suppressible amount per unit time may be calculated based on the load record for the past year, the demand plan, and the rules within the consumer 3A (for example, loosening the temperature setting of the air conditioner by X degrees when a DR request is made). Then, the adjustment capacity effective utilization application / non-application request generation function 231A sums up the possible contribution amount and the possible contribution amount per unit time and calculates the frequency distribution of the summed value. Also, the adjustment capacity effective utilization application / non-application request generation function 231A calculates the correlation of the response achievement probability. The correlation of the response achievement probability refers to the degree of fulfillment of the possible contribution amount with respect to a predetermined expected request amount (= possible contribution amount / expected request amount). Graphs 21A and 21B shown in FIG. 2A and FIG. 2B show the correlation of the response achievement probability obtained by such calculation, and the horizontal axis of the graphs 21A and 21B represents the expected request amount, and the vertical axis represents the response achievement probability. The adjustment capacity effective utilization application / non-application request generation function 231A calculates the relationship between the expected request amount and the response achievement probability shown in graphs 21A and 21B from the past operation status of the power generation equipment 3A4 used in the DR request and the past suppression status of the load 3A3, and stores this information. Next, the adjustment capacity effective utilization application / non-application request generation function 231A sets the expected request amount corresponding to a predetermined threshold as the maximum request amount that can be requested from the consumer 3A (called the response request limit amount).This predetermined threshold can be set arbitrarily, but may be set, for example, based on a contract between each consumer 3A, etc. and the aggregator. For example, if there is a contract that considers it successful if 90% of the requested amount of power suppression is achieved, the threshold may be set to 90%. Next, the adjustment capacity effective utilization application / non-application request generation function 231A sets an application / non-application judgment value. The application / non-application judgment value is the requested amount based on the contract between each consumer 3A, etc. and the aggregator (the amount of power suppression agreed upon by the aggregator and the consumer 3A in the contract). A consumer who is unable to fully contribute to the requested amount based on the contract will be the one who benefits from the effective utilization of adjustment capacity, so it is set as non-application, and a consumer who is able to fully contribute is said to be a consumer who can be expected to effectively utilize adjustment capacity, so it is set as application. If the corresponding request limit amount is equal to or greater than the application / non-application judgment value, the application / non-application request generation function 231A judges it to be "application" and transmits an "application request", and if it is less than the application / non-application judgment value, it judges it to be "non-application" and transmits a "non-application request". In addition, the adjustment capacity effective utilization application / non-application request generation function 231A generates response feasibility information shown in Fig. 2A and Fig. 2B as an example, and transmits it to the adjustment capacity effective utilization determination function 22A. The response feasibility information includes the relationship between the expected request amount and the response achievement probability, a predetermined threshold value for the response achievement probability, and an applicability determination value.

[0019] (operation) Next, the operation of the adjustment power effective utilization determination functions 22A to 22N will be described. It is assumed that the DR system server 20 receives the actual power suppression status of each consumer in response to the DR request from the DR system edge devices 23A to 23N, and judges that the adjustment of the requested amount by the adjustment capacity effective utilization method is necessary based on the aggregation result. It is also assumed that any one of "applied", "not applied", "automatic determination", and "server-side automatic determination" is set for the DR system edge devices 23A to 23N. Hereinafter, the consumer selection process to which the adjustment capacity effective utilization method is applied will be described with reference to FIG. 3, taking the adjustment capacity effective utilization determination function 22A as an example.

[0020] As described above, the adjustment power effective utilization determination function 22A receives from the DR system edge device 23A either an “application request,” a “non-application request,” or a “determination request,” as well as abnormality / fault information and response availability information of the equipment in the consumer 3A (step S11).

[0021] The adjustment capacity effective utilization determination function 22A determines whether an application request has been notified (step S12). If an application request has been notified (step S12; Yes), the adjustment capacity effective utilization determination function 22A sets the consumer 3A as a target of the adjustment capacity effective utilization method (step S20). If an application request has not been notified (step S12; No), the adjustment capacity effective utilization determination function 22A determines whether a non-application request has been notified (step S13). If a non-application request has been notified (step S13; Yes), the adjustment capacity effective utilization determination function 22A sets the consumer 3A as a non-target of the adjustment capacity effective utilization method (step S14).

[0022] If the non-application request has not been notified (step S13; No), the adjustment capacity effective utilization determination function 22A determines whether abnormality / failure information has been notified (step S15). If abnormality / failure information has been notified (step S15; Yes), the adjustment capacity effective utilization determination function 22A determines whether the consumer 3A can be a target of the adjustment capacity effective utilization method (step S16). For example, if the equipment for which the abnormality or failure has been notified is equipment not related to DR implementation (e.g., the load 3A1 and the power generation equipment 3A2 in FIG. 1), or if the equipment is not related to DR implementation but has a minor abnormality that does not affect operation, the adjustment capacity effective utilization determination function 22A determines that the consumer 3A can be a target of the adjustment capacity effective utilization method. If the equipment for which the abnormality or failure has been notified is equipment related to DR implementation (e.g., the power generation equipment 3A4 in FIG. 1) and has a serious abnormality or failure that affects operation, the adjustment capacity effective utilization determination function 22A determines that the consumer 3A cannot be a target of the adjustment capacity effective utilization method. When it is determined that the consumer 3A cannot be the target of the adjustment capacity effective utilization method (step S17; Yes), the adjustment capacity effective utilization determination function 22A sets the consumer 3A as not being the target of the adjustment capacity effective utilization method (step S14).

[0023] When it is determined that the consumer 3A can be a target of the adjustment capacity effective utilization method (step S17; No), the adjustment capacity effective utilization determination function 22A determines whether the consumer 3A can be a target of the adjustment capacity effective utilization method from the response possibility information (step S18). For example, as in the response possibility information illustrated in FIG. 2A, if the response request limit amount is larger than the application possibility judgment value, the adjustment capacity effective utilization determination function 22A determines that the consumer 3A can be a target of the adjustment capacity effective utilization method. As in the response possibility information illustrated in FIG. 2B, if the response request limit amount is smaller than the application possibility judgment value, the adjustment capacity effective utilization determination function 22A determines that the consumer 3A cannot be a target of the adjustment capacity effective utilization method. When it is determined that the consumer 3A cannot be a target of the adjustment capacity effective utilization method (step S19; Yes), the adjustment capacity effective utilization determination function 22A sets the consumer 3A as an exception to the target of the adjustment capacity effective utilization method (step S14). When it is determined that the consumer 3A can be a target of the adjustment capacity effective utilization method (step S19; No), the adjustment capacity effective utilization determination function 22A sets the consumer 3A as a target of the adjustment capacity effective utilization method (step S20).

[0024] When the adjustment capacity effective utilization determination function 22A determines whether the adjustment capacity effective utilization method is applied to the consumer 3A according to the processing flow of FIG. 3, it notifies the adjustment capacity effective utilization calculation function 21 of the determination result. The adjustment capacity effective utilization determination function 22B to 22N also execute similar determination processing, and notifies the adjustment capacity effective utilization calculation function 21 of the determination result. The adjustment capacity effective utilization calculation function 21 adjusts the requested amount by allocating the excess or shortage with respect to the DR request amount to the consumer determined to "apply" the adjustment capacity effective utilization method, and notifies the DR system edge device 23A, etc. of the adjusted requested amount through the adjustment capacity effective utilization determination function 22A, etc. (the consumer 3A is the application target). The DR system edge device 23A controls the equipment in the consumer 3A based on the adjusted requested amount. The same processing is executed in the other consumers that are the application targets. As a result, the DR request amount from the general electricity transmission and distribution company system 1 can be achieved.

[0025] In the flowchart of Figure 3, when an application request is transmitted, the consumer is made a target for application of the adjustment power effective utilization method. However, as a precaution, the processing of steps S15 to S19 may be performed even when an application request is transmitted.

[0026] (effect) Conventionally, the adjustment capacity effective utilization method was often applied or not applied uniformly to consumers under the DR system. In contrast, according to the present embodiment, an "application request" or "non-application request" can be transmitted from the DR system edge device 23A, etc. installed in each consumer 3A, etc., and the application or non-application of the adjustment capacity effective utilization method is determined for each consumer based on this request. This makes it possible to prevent, for example, consumers who do not want to be included in the adjustment capacity effective utilization method from being forced to participate in the adjustment capacity effective utilization. In addition, when a "judgment request" is transmitted, it is judged whether the consumer has the ability to respond to the DR request, and then the application or non-application of the adjustment capacity effective utilization method is determined, so that the flexibility of DR response is ensured and the occurrence of penalty costs when DR fails can be avoided.

[0027] FIG. 4 is a diagram illustrating an example of a hardware configuration of the selection system according to each embodiment. The computer 900 includes a CPU 901 , a main memory device 902 , an auxiliary memory device 903 , an input / output interface 904 , and a communication interface 905 . The above-mentioned DR system server 20 and DR system edge devices 23A to 23N are implemented in a computer 900. The above-mentioned functions are stored in the auxiliary storage device 903 in the form of a program. The CPU 901 reads the program from the auxiliary storage device 903, loads it in the main storage device 902, and executes the above-mentioned processing in accordance with the program. The CPU 901 also secures a storage area in the main storage device 902 in accordance with the program. The CPU 901 also secures a storage area in the auxiliary storage device 903 for storing data being processed in accordance with the program.

[0028] In addition, a program for realizing all or part of the functions of the DR system server 20 and the DR system edge devices 23A to 23N may be recorded in a computer-readable recording medium, and the program recorded in the recording medium may be read into a computer system and executed to perform processing by each functional unit. The term "computer system" as used herein includes hardware such as an OS and peripheral devices. In addition, if a WWW system is used, the term "computer system" also includes a homepage providing environment (or display environment). In addition, the term "computer-readable recording medium" refers to a portable medium such as a CD, DVD, or USB, and a storage device such as a hard disk built into a computer system. In addition, when the program is distributed to a computer 900 through a communication line, the computer 900 that receives the program may deploy the program in the main storage device 902 and execute the above processing. In addition, the above program may be for realizing part of the above-mentioned functions, and may further be capable of realizing the above-mentioned functions in combination with a program already recorded in the computer system.

[0029] As described above, several embodiments according to the present disclosure have been described, but all of these embodiments are presented as examples and are not intended to limit the scope of the invention. These embodiments can be implemented in various other forms, and various omissions, substitutions, and modifications can be made without departing from the gist of the invention. These embodiments and their modifications are included in the scope of the invention and its equivalents as described in the claims, as well as in the scope and gist of the invention.

[0030] <Additional Notes> The selection device, the demand response system, and the selection method described in the embodiments can be understood, for example, as follows.

[0031] (1) A selection device according to a first aspect includes a determination unit that determines which consumers should be subject to an adjustment capacity effective utilization method, which is a method for achieving the requested amount of a demand response request by adjusting the amount of power suppression borne by the consumer when the requested amount cannot be achieved, and which consumers should not be subject to the method. By determining whether or not to apply the adjustment capacity effective utilization method for each consumer, it is possible to select consumers to which the adjustment capacity effective utilization method is applied.

[0032] (2) A selection device according to a second aspect is a selection device according to (1), wherein, when the determination unit receives request information from an edge device of the consumer indicating that the application of the adjustment capacity effective utilization method is not desired, the determination unit determines that the adjustment capacity effective utilization method will not be applied to the consumer. This makes it possible to exclude consumers who do not wish to apply the adjustment capacity effective utilization method from the scope of application.
