  The instruction unit 12 sets the content of a new request for the customer 90 according to the classification of the customer 90 classified by the classification unit 15.

  Specifically, the storage unit 13 stores a customer management table indicating the correspondence between customer identification information and classification. The classification unit 15 newly registers the customer 90 in the customer management table based on the classification result of the customer 90 or changes the classification of the customer 90 registered in the customer management table.

  In addition, the storage unit 13 stores a customer instruction table indicating a correspondence relationship between a customer category and information used as a reference for creating and transmitting instruction information.

  Based on the request information received from the grid-side acquisition unit 11 and the customer management table and customer instruction table stored in the storage unit 13, the instruction unit 12 requests power consumption among a plurality of consumers 90. One or a plurality of consumers 90 to be selected are selected, and instruction information for the selected consumers 90 is created. Then, the instruction unit 12 transmits the generated instruction information to the selected customer 90. The instruction unit 12 may be configured to create instruction information having different contents for each consumer, or may be configured to create instruction information having common contents for some or all of the consumers 90.

  For example, in the customer instruction table, a priority is assigned to each of a plurality of sections. The instruction unit 12 determines a customer 90 to be requested based on the priority.

  FIG. 4 is a diagram showing an example of a customer instruction table in the power consumption management apparatus according to the embodiment of the present invention.

  Referring to FIG. 4, in the customer instruction table, the customer of section A1 expresses participation in DR, succeeds in DR, that is, succeeds in achieving the power saving target notified from power consumption management device 101, and It is a customer who has performed DR, that is, has performed an operation in accordance with a request from the power consumption management apparatus 101. The customer of the category A1 has a high probability of DR success. Therefore, in the subsequent requests, the priority is 1, the amount of suppression requests is increased, and the incentive, that is, the consideration is increased.

  The customer of Category A2 is a customer who expressed participation in DR, succeeded in DR, and did not implement DR. The customer of the category A2 has a low probability of DR success. Therefore, in the next and subsequent requests, the priority is 2, the amount of suppression requests does not change, and the incentive is deferred.

  That is, the instruction unit 12 sets a new request for the customer 90 with different contents depending on whether or not an operation according to the request regarding power consumption has been executed.

  The customer of category B1 is a customer who expressed participation in DR, failed DR, and implemented DR. The customer of category B1 has a low probability of DR success, and needs to remove an obstacle to DR success or adjust the amount of request for suppression. For this reason, in the next and subsequent requests, the priority is 3, the amount of suppression requests is reduced, and the incentive is deferred.

  The customer of category B2 is a customer who expressed participation in DR, failed in DR, and did not implement DR. The customer of the category B2 has a low probability of DR success. Therefore, in the subsequent requests, the priority is 6, the amount of suppression requests is reduced, and the incentive is reduced.

  The customer of category C1 is a customer who expressed non-participation in DR, succeeded in DR, and implemented DR. The customer of the category C1 is not subject to DR accuracy evaluation and needs to encourage participation in DR. For this reason, in the next and subsequent requests, the priority is 4, the amount of suppression requests remains the same, and the incentive is deferred.

  The customer of Category C2 is a customer who expressed non-participation in DR, succeeded in DR, and did not perform DR. The customer in category C2 is not subject to DR accuracy evaluation, and has succeeded in DR due to factors other than the DR implementation by the customer. For this reason, in the next and subsequent requests, the priority is 5, the amount of suppression requests is reduced, and the incentive is deferred.

  The customer of category D1 is a customer who expressed non-participation in DR, failed in DR, and implemented DR. The customer of the category D1 is not subject to DR accuracy evaluation, and needs to promote participation in the DR, remove an obstacle to the success of the DR, or adjust the amount of request for suppression. For this reason, in the subsequent requests, the priority is 7, the amount of suppression requests is reduced, and the incentive is reduced.

  The customer of category D2 is a customer who expressed non-participation in DR, failed in DR, and did not perform DR. The customer of the category D2 is not subject to DR accuracy evaluation. Therefore, in the subsequent requests, the priority is 8, the amount of suppression requests is reduced, and the incentive is reduced.

  Referring again to FIG. 3, the consideration calculating unit 19 calculates a consideration for satisfying a demand related to power consumption by the customer 90. More specifically, the consideration calculation unit 19 refers to a customer management table stored in the storage unit 13 to calculate a consideration of a value according to the classification of the customer 90 classified by the classification unit 15. .

  Here, the customer management table indicates, for example, the correspondence between customer identification information, classification, and incentives.

  The consideration calculating unit 19 registers the calculated consideration of the consumer in, for example, the consumer management table. The consideration registered in the customer management table is given to the customer 90 who has succeeded in the DR.

  The classification unit 15 may be configured to determine the classification of the customer 90 by averaging or weighting the results of the customer 90 with respect to the instruction information for a plurality of times to the facility device 31.

  Next, the operation when the power consumption management system according to the embodiment of the present invention makes a request for power consumption will be described.

  FIG. 5 is a diagram showing an example of a sequence of power consumption suppression processing in the power consumption management system according to the embodiment of the present invention. In FIG. 5, for ease of understanding, consumers and facilities in one power demand facility 301 are representatively shown.

  With reference to FIG. 5, first, the grid-side management device 151 predicts power demand, and determines that power consumption should be suppressed when there is a high possibility that power supply and demand will be tight. And the system side management apparatus 151 transmits the request information which shows the power saving period and the upper limit of the power consumption in the said power saving period as a target value to the power consumption management apparatus 101, for example (step S11).

  Next, the power consumption management apparatus 101 receives the request information from the grid-side management apparatus 151, creates instruction information based on the suppression target indicated by the received request information, and is selected as a request destination for power consumption 1 or It transmits to the plurality of facility apparatuses 31 (step S12).

  Next, the facility apparatus 31 receives the instruction information from the power consumption management apparatus 101, creates screen information based on the received instruction information, and transmits it to the terminal device 33 of the customer 90, for example (step S13).

  Next, the customer 90 confirms the screen display of the terminal device 33 and determines whether or not to participate in DR. And the consumer 90 transmits the response information which shows a judgment result to the facility apparatus 31, for example by operating the terminal device 33 (step S14).

  Next, the facility apparatus 31 transmits the response information received from the customer 90 to the power consumption management apparatus 101 (step S15).

  Next, when the customer 90 determines to participate in DR, for example, at the start timing of the power saving period, the operation information of the device 32 is changed by operating the remote controller or the like to transmit control information to the device 32 ( Step S16).

  Next, the consumer 90 transmits the implementation information which shows whether DR was implemented by operating the terminal device 33, for example to the facility apparatus 31 (step S17).

  Next, the facility apparatus 31 transmits the implementation information received from the customer 90 to the power consumption management apparatus 101 (step S18).

  Next, the facility apparatus 31 transmits a measurement result request to the watt hour meter 35, for example, at the end timing of the power saving period (step S19).

  Next, the watt-hour meter 35 receives the measurement result request from the facility apparatus 31 and transmits the measurement result such as the total power consumption in the power demand facility 301 to the facility apparatus 31 (step S20).

  Note that the watt-hour meter 35 is not limited to a configuration that receives and responds to a measurement result request from the facility device 31, but may be configured to transmit the measurement result to the facility device 31 regularly or irregularly.

  Next, the facility apparatus 31 creates measurement information indicating the amount of power consumption in the facility apparatus 31 during the power saving period based on the measurement result received from the watt-hour meter 35, and transmits the measurement information to the power consumption management apparatus 101 (step). S21).

  Next, the power consumption management apparatus 101 determines the category of the customer 90 corresponding to the facility apparatus 31 based on the response information, the execution information, and the measurement information received from the facility apparatus 31 (step S22).

  Next, the power consumption management apparatus 101 calculates the value of the next incentive for the customer 90 according to the determined category (step S23).

  Next, the power consumption management apparatus 101 registers the classification result of the consumer 90 and the incentive calculation result in the consumer management table (step S24).

  Next, when there is a high possibility that power supply and demand will be tight, the grid-side management device 151 determines that power consumption should be suppressed, and transmits new request information to the power consumption management device 101 (step S25). ).

  Next, the power consumption management apparatus 101 receives the request information from the system side management apparatus 151, and creates instruction information based on the suppression target indicated by the received request information. More specifically, the power consumption management apparatus 101 uses one or more request destinations related to power consumption so as to satisfy the suppression target indicated by the received request information using the updated customer instruction table and customer management table. The customer 90 is selected, and the content of the request regarding power consumption, that is, the content of the instruction information is set. The power consumption management apparatus 101 selects, for example, as a request destination in order from the customer 90 with a priority of 1 until a total suppression amount that satisfies the suppression target is obtained (step S26).

  Next, the power consumption management apparatus 101 transmits the created instruction information to one or a plurality of facility apparatuses 31 selected as request destinations regarding power consumption (step S27).

  In the sequence shown in FIG. 5, the customer 90 performs a device operation for performing or not performing the DR, and notifies the facility apparatus 31 of the execution result. As an advantage of such a method, a new facility such as the introduction of a device 32 that can communicate with the facility apparatus 31 is unnecessary. On the other hand, as disadvantages, the customer 90 does not always perform an operation for performing DR, and wrong or wrong implementation of DR for the device 32, or wrong notification content to the facility apparatus 31. There are points to do.

  FIG. 6 is a diagram illustrating an example of a sequence of power consumption suppression processing in the power consumption management system according to the embodiment of the present invention.

  Referring to FIG. 6, the operations in steps S31 to S36 are the same as the operations in steps S11 to S16 shown in FIG.

  Next, the facility apparatus 31 transmits a status request to the device 32 (step S37).

  Next, the device 32 transmits a state response indicating its own state to the facility apparatus 31 (step S38).

  Next, the facility apparatus 31 determines whether or not DR has been performed based on the state response received from the device 32 (step S39), and transmits implementation information indicating the determination result to the power consumption management apparatus 101 ( Step S40).

  The operations in steps S41 to S49 are the same as the operations in steps S19 to S27 shown in FIG.

  In the sequence illustrated in FIG. 6, the facility apparatus 31 determines whether or not DR is performed based on the state of the device 32. The advantage of such a method is that the state of the device 32 is automatically notified, while the operation of the device 32 is not automatically changed, so that the safety is relatively high. On the other hand, the disadvantages include that there are few devices 32 from which the facility apparatus 31 can acquire the state, and that it is difficult to determine whether to perform DR. For example, when the cooling setting is 25 degrees, DR is performed if the normal set temperature is 20 degrees. However, if the normal set temperature is 28 degrees, the DR is not performed and determination is difficult. It is.

  FIG. 7 is a diagram showing an example of a sequence of power consumption suppression processing in the power consumption management system according to the embodiment of the present invention.

  Referring to FIG. 7, the operations in steps S51 to S56 are the same as the operations in steps S11 to S16 shown in FIG.

  Next, the device 32 transmits execution information indicating whether or not DR has been executed to the facility apparatus 31 (step S57).

  Next, the facility apparatus 31 transmits the implementation information received from the device 32 to the power consumption management apparatus 101 (step S58).

  The operations in steps S59 to S67 are the same as the operations in steps S19 to S27 shown in FIG.

  In the sequence shown in FIG. 7, the implementation result is notified from the device 32 to the facility apparatus 31 in conjunction with the DR implementation by the customer 90. As an advantage of such a method, it is possible to reliably notify the implementation of DR. On the other hand, a disadvantage is that there are few devices 32 that can notify the implementation result.

  FIG. 8 is a diagram illustrating an example of a sequence of power consumption suppression processing in the power consumption management system according to the embodiment of the present invention.

  Referring to FIG. 8, the operations in steps S71 to S75 are the same as the operations in steps S11 to S15 shown in FIG.

  Next, when the facility apparatus 31 receives response information to participate in DR from the customer 90, the facility apparatus 31 creates control information and transmits the control information to the apparatus 32, thereby changing the operation content of the apparatus 32 (step S76). ).

  Next, the facility apparatus 31 transmits execution information indicating whether or not DR has been performed to the power consumption management apparatus 101 (step S77).

  The operations in steps S78 to S86 are the same as the operations in steps S19 to S27 shown in FIG.

  In the sequence shown in FIG. 8, the device 32 is controlled in conjunction with a DR participation expression from the customer 90, and the implementation result is notified to the power consumption management apparatus 101. As an advantage of such a method, it is possible to prevent the customer 90 from forgetting to perform the DR just by expressing the participation. On the other hand, the disadvantages are that there are few devices 32 that can be controlled by the facility apparatus 31, and in order to allow the facility apparatus 31 to operate the devices 32, such as devices and facilities, specifically, the EchonetLite (registered trademark) standard. It is necessary to have a device compatible with the above, an operation system using a learning remote controller, or an on / off mechanism using a contact. In addition, if the situation changes after the customer 90 has answered whether or not to participate in the power consumption management apparatus 101, it is possible to forget to change the implementation and non-implementation of DR, and it is safe by automatically operating the device. The point that a property may fall is mentioned.

  Here, in OpenADR, which is a standard protocol for DR that controls supply and demand by increasing or decreasing power consumption on the consumer side, power demand is controlled by transmitting a DR signal from the DRAS (Demand Response Automation Server) to the consumer. be able to. Also, the DRAS can receive a response indicating whether or not to participate in DR.

  The DRAS operates as an OpenADR server (VTN: Virtual Top Node). The customer side device operates as a client (VEN: Virtual End Node) of OpenADR.

  The aggregator controls a power demand by collecting a plurality of consumers. The DRAS for the aggregator operates as an OpenADR client (VEN) for the DRAS for the electric power company, and operates as a server (VTN) for the device on the customer side.

The DRAS for the electric power company is an example of the system-side management device 151, and the DRAS for the aggregator is an example of the power consumption management device 101.
In OpenADR, the power usage amount of a consumer can be transmitted to DRAS. The DRAS can acquire the response of whether or not the customer can participate in the DR signal and the power usage amount during the DR period, but cannot acquire information on whether or not the customer actually performed the DR. For this reason, it is not possible to distinguish between the case where the customer performs DR and the case where the demand naturally increases or decreases due to the influence of temperature or the like.

  In contrast, in the power consumption management system according to the embodiment of the present invention, it is determined whether DR has been performed from the customer side system to DRAS, specifically from the facility apparatus 31 to the power consumption management apparatus 101. A notification feature has been added.

  FIG. 9 is a diagram showing an example of a DR implementation notification process sequence in the power consumption management system according to the embodiment of the present invention.

  Referring to FIG. 9, as a method for notifying whether or not DR has been implemented, there is a method 1 in which mapping is performed on a “report” that realizes an OpenADR notification function.

  In OpenADR, for example, a measurement value such as a smart meter and a state such as a set temperature of an air conditioner can be defined as a measurement target (rID) and transmitted in a report.

  That is, whether or not DR has been implemented is defined as rID, and can be transmitted as a report by treating it as a measurement target in the DRAS and the customer side system (hereinafter also referred to as the customer system).

  Specifically, first, the customer system transmits to the DRAS a report capability notification indicating that the execution or non-execution of DR can be notified as an rID (step S101).

  Next, the DRAS receives the report capability notification from the customer system, and transmits a definition report transmission request for requesting a report indicating implementation or non-execution of the DR to the customer system (step S102).

  Next, the DRAS transmits a DR signal to the customer system (step S103), and the customer system transmits a DR participation permission response to the DRAS (step S104).

  Next, the customer system transmits a report indicating implementation or non-execution of DR to the DRAS (step S105).

  Next, a consumer system transmits the report which shows electric power consumption as a measured value to DRAS (step S106).

  The advantage of Method 1 is that it can be transmitted using OpenADR2.0b. On the other hand, the disadvantage is that the OpenADR2.0b processing unit of the customer system may not be able to handle such as when an off-the-shelf program is used.

  As another method 2, the OpenADR transport protocol is used, that is, the transport protocol packet such as XMPP or HTTP (s) used in the lower layer of the OpenADR communication is stored and notified in a unique format. A way to do this is conceivable.

  For example, the DRAS and the customer system are connected by XMPP or HTTP, and can transmit and receive XML data according to OpenADR2.0b.

  Alternatively, the DRAS and the customer system are connected by XMPP or HTTP, and instead of the XML data, data indicating whether the DR is implemented or not is transmitted from the customer system to the DRAS. The format of the transmission data is arbitrary.

  The advantage of Method 2 is that it can be applied to a customer system that cannot support Method 1. In addition, since OPenADR2.0b is used, it is guaranteed that communication is possible. On the other hand, a disadvantage is that the transport protocol may not be used due to a lack of communication capacity.

  As another method 3, a method in which another protocol is prepared and transmitted instead of XMPP or HTTP in method 2 can be considered.

  Advantages of method 3 include that it can be applied to a customer system that cannot support method 1 and method 2, and that automatic processing is possible, as in methods 1 and 2. On the other hand, there are disadvantages in that it is necessary to prepare an environment so that communication can be performed with the protocol to be used, and that the DRAS side needs to be supported for each protocol to be used.

  As another method 4, a method using e-mail instead of the protocol of method 3 can be considered. The e-mail is generally processed by an operator, but automatic processing is also possible by using a standard mail.

  Advantages of Method 4 include that it can be applied to a customer system that is not compatible with Method 1-3, and that automatic processing is possible if it is devised, such as using a standard mail. On the other hand, there are disadvantages in that it is necessary to prepare an environment so that e-mail can be transmitted, and in general, automatic processing cannot be performed and human intervention is required.

  As another method 5, instead of the protocol, a method of transmitting by communication means such as telephone and FAX and inputting via an operator can be considered.

  Advantages of Method 5 are that it can be applied to a customer system that is not compatible with Method 1-4, and the use of a telephone, a fax, or the like and the intervention of a person eliminates the need for DRAS and customer system development. A point is raised. On the other hand, the disadvantages are that it is necessary to prepare communication means such as a telephone to be used and that human intervention is required.

  In the power consumption management system 401, any of the above method 1 to method 5 can be adopted as a method for notifying whether or not DR is implemented.

  In the power consumption management system according to the embodiment of the present invention, the response information is information indicating whether or not to participate in DR, that is, whether or not to comply with a request regarding power consumption, but is limited to this. It is not a thing. The response information may be information indicating, as a percentage, the probability of complying with the request regarding power consumption. In this case, the power consumption management apparatus 101 determines whether or not the customer 90 can participate in DR depending on, for example, whether or not the probability is equal to or higher than a predetermined threshold.

  In the power consumption management system according to the embodiment of the present invention, the execution information is information indicating whether or not DR has been performed, that is, whether or not an operation according to a request regarding power consumption has been performed. However, the present invention is not limited to this. The implementation information may be information indicating the accuracy with which DR is implemented, as a percentage or the like. In this case, for example, the power consumption management apparatus 101 determines whether or not the DR is performed by the customer 90 depending on whether or not the accuracy is equal to or higher than a predetermined threshold.

  Further, although the power consumption management apparatus 101 is configured to determine the success of the DR from the measurement result of the watt-hour meter 35, the present invention is not limited to this. The power consumption management apparatus 101 may be configured to determine the success of DR from other information such as an input operation from the user.

  Moreover, the power consumption management apparatus 101 may be configured not to include the determination unit 17 and to classify the consumers 90 without using information on whether or not the customer 90 satisfies the request.

  Moreover, the power consumption management apparatus 101 may not include the consideration calculation unit 19 and may not be configured to calculate an incentive for the customer 90.

  By the way, even if the demand for power consumption is requested from the consumer and the demand from the power company is satisfied, the demand for power may have decreased naturally due to the influence of temperature, etc. It is not always true that consumption has been reduced. A technology that more reliably satisfies the demand for reducing power consumption is desired.

  On the other hand, in the power consumption management device according to the embodiment of the present invention, the consumer side acquisition unit 14 receives response information regarding whether or not the consumer 90 is scheduled to follow a request regarding power consumption, and the consumer 90. The execution information regarding whether or not the operation according to the request has been executed is acquired. The classification unit 15 classifies the customer 90 into any of a plurality of categories based on the response information and the execution information acquired by the customer side acquisition unit 14. And the instruction | indication part 12 sets the content of the new request | requirement with respect to the consumer 90 according to the classification | category of the said consumer 90 classified by the classification | category part 15. FIG.

  In this way, in addition to information on whether or not a customer can participate in DR, in addition to information on whether or not DR is implemented, the success of DR is due to, for example, a natural decrease in power demand. It can be discriminated whether the customer is actually due to DR. Then, taking into account this discrimination result, it is possible to classify the customers in detail, select the DR request destination customer according to the classified customer category, and set the request contents Therefore, it is possible to select an appropriate target person as a request destination for power consumption and satisfy the request from the electric power company more reliably.

  Therefore, in the power consumption management device according to the embodiment of the present invention, it is possible to cause the consumer to more reliably perform the operation according to the request regarding the power consumption.

  In addition, even if customers who are unlikely to contribute to the success of DR are subordinated, each customer can be classified into a detailed and appropriate category, thus satisfying the demands from electric power companies more reliably. , The capacity of the system for DR requirements can be increased.

  In the power consumption management apparatus according to the embodiment of the present invention, the determination unit 17 determines whether or not the customer 90 satisfies the request. Then, the classification unit 15 classifies the customers 90 based on the response information, the implementation information, and the determination result of the determination unit 17.

  Thus, in addition to the information regarding whether or not the DR participation from the customer and the information regarding whether or not the DR is implemented, the configuration using the information indicating whether or not the DR has been successful makes the consumer more detailed and appropriate. Can be classified into various categories.

  Moreover, in the power consumption management apparatus according to the embodiment of the present invention, the consideration calculation unit 19 calculates a consideration for the customer 90 satisfying the request. Then, the consideration calculation unit 19 calculates a consideration of a value according to the classification of the customer 90 classified by the classification unit 15.

  With such a configuration, it is possible to give an appropriate incentive according to the classified consumer classification to the consumer. For example, in the case where there are a plurality of consumers with the same amount of power consumption suppression, it is possible to give a preferential treatment to a customer who has intentionally suppressed power consumption.

  Moreover, in the power consumption management apparatus according to the embodiment of the present invention, priority is assigned to each of a plurality of sections. And the instruction | indication part 12 determines the consumer 90 which should be made the object of a request | requirement based on the said priority.

  With such a configuration, it is possible to easily select an appropriate consumer as a DR request destination using the priority assigned to each category.

  Moreover, in the power consumption management apparatus according to the embodiment of the present invention, the instruction unit 12 sets a new request for the customer 90 with different contents depending on whether or not the operation according to the request has been executed.

  With such a configuration, different request contents are set depending on whether or not processing for suppressing power consumption is intentionally performed for a plurality of consumers who have expressed their participation in DR and who have succeeded in DR. be able to.

  The above embodiment should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.

  The above description includes the following features.
