Description

  The present invention relates to an aggregator-side system, a prosumer-side system, an aggregation system, and an aggregation method for aggregating (aggregating) energy resources.

  Patent Literature 1 discloses a technique for improving the possibility of executing a demand response (Demand Response) on a resource (a power generation device, a load device, or the like) of a customer in response to an operation performed by an operator of a power aggregator. It has been known.

  The power control device described in Patent Literature 1 includes a prediction unit, a selection unit, and an execution unit, and each unit functions as follows.

  The prediction unit predicts, for each user, user availability, which is a possibility that the user causes the resource to execute the demand response. The selection unit selects a resource based on a predetermined condition to be satisfied by the resource to execute the demand response and user availability. The execution unit causes the selected resource to execute a demand response.

  In addition, the power company apparatus 10 transmits information indicating an incentive to the power control apparatus 30 according to the execution result of the demand response. The information indicating the incentive indicates, for example, that the information indicates the incentive according to the execution result to the user, such as value information such as the amount of money. In addition, regarding the user availability, when the amount of change in power consumption of the resource 21 is relatively large, it is highly likely that the user is near the associated resource 21.

  Further, the prediction unit 32 may predict the user availability based on the amount of change in the power consumption of the resource 21 of the user system 20. For example, the availability is such that the prediction unit 32 may predict the user availability of the user associated with the resource 21-n to a higher value as the change amount of the power consumption of the resource 21-n is larger. We believe that it depends a lot on the distance between resources and users.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a block diagram illustrating a configuration example of the energy resource aggregation system according to the first embodiment of the present invention. First, the overall configuration of the energy resource aggregation system according to the present invention will be described with reference to FIG.

  The energy resource aggregation system is composed of an aggregator system 110 and a prosumer system 120 in a narrow sense. In a broad sense, the system further includes an energy service user company side system 160 that requires supply and demand adjustment, and a power system 190. In FIG. 1, the aggregator-side system 110, the prosumer-side system 120, and the energy service usage provider-side system 160 are shown as one set each, but each of them is generally composed of a plurality of systems.

  Here, the prosumer refers to an adjustment such as an increase or decrease in demand (hereinafter referred to as demand adjustment) or an adjustment of generated power (hereinafter referred to as generated power adjustment) in response to a request of a power provider such as an aggregator and a transmission and distribution system operator. This is the company that implements it. In addition, a power generation device and power consumption equipment used for demand adjustment and generated power adjustment are referred to as energy resources, and a service that performs generated power adjustment and demand adjustment in response to a request from a power provider is referred to as a resource service. In this specification, there is a case where power adjustment includes generation power adjustment and demand adjustment.

  Both the aggregator and the prosumer are one of the power providers, but in the present invention, the provider that provides the resource service is referred to as the prosumer, and the power adjustment (from the viewpoint of stabilizing the power system, balancing the supply and demand, and securing the grid coordination power, etc.) The power adjustment in this case includes generation power adjustment and demand adjustment) by using an energy service provider, one or more prosumer resource services, and the amount of power adjustment, start time, and period. Aggregators are called aggregators in a form suitable for energy service users. Also, the service provided by the aggregator to the energy service user is referred to as an energy service.

  As described above, the aggregator-side system 110, the prosumer-side system 120, and the energy service provider-side system 160 of FIG. 1 are each generally composed of a plurality of systems to form the energy resource aggregation system of the present invention. However, when viewed from one aggregator-side system 110, this aggregator-side system 110 is used by being connected to at least one or more prosumer-side systems 120 and one or more energy service user-side systems 160. You.

  The aggregator-side system 110 in FIG. 1 includes a resource model 111 for each consumer for planning resource services by the prosumer-side system 120, a planning unit 113, and a communication unit 112 for communicating with the prosumer-side system and the energy service user. A condition database 114 is provided.

  The prosumer-side system 120 includes one or more energy resources 131 and the terminal device 121, and one or more communication units 132 that perform communication between the energy resources 131 and the aggregator-side system 110. The terminal device 121 includes a display unit 123, a communication unit 122, an individual evaluation index KPI measurement unit 124, and an input unit 125. You may comprise so that it may have the positioning part 126. The communication unit 122 may be configured to be able to communicate with the external information service 150.

  The energy service utilization company side system 160 and the energy resource 131 are configured to transmit and receive power via the power system 190.

  According to the operation of the power system 190 shown in FIG. 1, the demand adjustment and the generated power adjustment of the power system 190 are executed by controlling and adjusting the energy resources 131 in the prosumer system 120. On the other hand, an energy service user who stably manages and operates the power system executes a power forecast in the future by the energy service user company system 160, and determines whether there is excess or insufficient power (energy resources) required for stable operation. Determine the amount. The excess or deficiency is, for example, the excess or deficiency of power for 24 hours tomorrow, or the excess or deficiency of power one hour later on the day. The aggregator-side system 110 provides the plurality of prosumer-side systems 120 with an amount of demand adjustment that they can bear (hereinafter referred to as demand adjustment) in order to secure the excess or deficiency of the power determined by the energy service utilization operator-side system 160. The amount of generated power adjustment and the amount of generated power adjustment (hereinafter referred to as generated power adjustment amount) are confirmed, and the demand adjustment amount and generated power adjustment amount shared by each prosumer-side system 120 are determined. Each prosumer-side system 120 controls and adjusts the energy resources 131 so as to achieve the demand adjustment amount and the generated power adjustment amount whose sharing is determined. The power secured in the aggregator system 110 is reported to the energy service user company system 160.

  In FIG. 1, the prosumer is not only a company that handles large power, but also a company that handles small power in many cases. For this reason, generally, the consumer system 120 has a simple system configuration including a terminal device 121 such as a PC, and the communication unit 122 and the like may use an Internet line. The software for the processing in is preferably in a form that can be obtained by downloading from the cloud.

  The system configuration of the prosumer-side system 120 in FIG. 1 includes a communication unit 132 formed between the communication unit 112 in the aggregator-side system 110 and the energy resource 131, in addition to the communication unit 122 in the terminal device 121. According to this configuration, the energy resource 131 can be directly remotely controlled from the aggregator-side system 110 via the communication unit 132.

  Further, the system configuration of the prosumer side system 120 of FIG. 1 includes another communication unit 122. In this case, the information from the aggregator system 110 obtained via the communication unit 122 is displayed on the display unit 123 of the terminal device 121, and the air operator M operates the input unit 125 while confirming the displayed contents. By doing so, various data input work and confirmation work are performed. The input data from the input unit is input to the communication unit 122 and displayed on the display unit, or transmitted to the aggregator-side system 110.

  FIG. 2 is a block diagram illustrating another configuration example of the energy resource aggregation system according to the first embodiment of the present invention. In FIG. 2, components similar to those in FIG. 1 and having the same functions are denoted by the same reference numerals. In the prosumer-side system 120 having the configuration shown in FIG. 1, the communication unit is configured by 122 and 132, whereas in the prosumer-side system 120 shown in FIG. Is shown.

  FIG. 2 shows a configuration in which the communication unit 222 in the terminal device 121 of the prosumer-side system 120 can communicate with the energy lease 131 and acquire control, status, and actual values. For example, the embodiment of FIG. 1 corresponds to a case where the energy resource 131 supports a standard communication protocol such as EchonetLite and can be directly monitored and controlled from the aggregator-side system 110 through the communication device 132.

  Although not shown, the energy resources 131 as shown in FIG. 1 and the energy resources as shown in FIG. 2 may be mixed.

  In addition, there is no communication device 132 that directly connects the energy resource 131 and the aggregator system 110, and monitoring and control cannot be performed directly from the aggregator system 110, or the energy resource itself does not support a standard communication protocol, Communication with the aggregator system 110 may not be possible. In such a case, the user of the prosumer-side system 120 may manually operate the system, manually input the operation results and status to the terminal device, and communicate with the aggregator-side system through the communication units 122 and 222. For example, the operator of the aggregator-side system 120 may manually perform the operation, and transmit the result in the form of a photograph on an operation panel. In such a case, if the data received by the communication unit 112 of the aggregator-side system 110 includes a photograph, the operation result may be confirmed by image processing. It may be determined that the operation instructed by the photograph being sent is performed.

  Next, the operation and processing of each component in the system of FIG. 1 will be described.

  First, the aggregator system 110 will be described. The aggregator-side system 110 starts a series of operations by receiving, by the communication unit 112, the information S1 of the excess or deficiency of the power determined by the energy service usage provider-side system 160. Here, first, the planning unit 113 takes in the prosumer model information S2 from the prosumer-specific resource model 111 and also takes in the allowable condition information S3 from the allowable condition database 114.

  Here, the prosumer-specific resource model 111 in the aggregator-side system 110 is a prosumer model used by the planning unit 113 to plan an energy service to an energy service user. For example, for each energy resource 131 of the prosumer, the relationship between the generated power adjustment amount and the duration or the demand adjustment amount and the duration and the amount specified as the individual evaluation index KPI (key performance indicator) of the prosumer is calculated. It is modeled in a possible form. Computable models include, but are not limited to, neural networks, regression models, membership functions, physical equations, look-up tables, and the like. The individual evaluation index KPI is a main performance evaluation index for evaluating the degree of achievement of a target (such as a company). Further, the prosumer-side system 120 includes a plurality of energy resources 131 and may be individually controllable. Therefore, the resource model 111 for each consumer is prepared for each energy resource 131.

  The permissible condition database 114 in the aggregator-side system 110 stores the permissible value of the amount of change of the individual evaluation index value (KPI value) that varies depending on the resource service for each consumer and the price of the resource service. The allowable value is set for each class of environmental conditions.

  Environmental conditions include, for example, season / day / time, temperature / humidity, solar radiation / precipitation, wind direction / velocity, typhoons, volcanic eruptions / smoke, smog, yellow sand, snow cover, etc., electricity market prices, renewable energy This is information in which a predicted value is obtained in advance, such as the amount of power generation, and an actual value is obtained later, and is a combination of at least one or more of which is classified into at least one of the presence or absence and the degree. In the present invention, it is assumed that the environmental conditions include information such as the season, the day of the week, and the time when it is known in advance that it will come without being predicted.

  As will be described later, the allowable condition registered in the allowable condition database 114 in the aggregator-side system 110 is preferably configured to be arbitrarily set by the prosumer in accordance with the circumstances of the individual prosumer. On the basis of the display information displayed on the display unit 123 of the terminal device 121 in the side system 120, the setting can be manually performed by operating the input unit 125 by the operator M who is a user. It is registered in the condition database 114. However, in a configuration in which the prosumer-side system 120 can communicate with the external information service 150, for example, when the prosumer is a farmer, a contracted agricultural weather information may be used.

  Here, an example of a screen configuration of the display unit 123 when displaying on the display unit 123 of the prosumer system 120 and setting various conditions using the input unit 125 will be described. First, the environmental condition may include an operating state unique to the prosumer. For example, keywords related to prosumer-specific tasks such as during business hours, preparations, the busiest period, and the recommended date of leaving work on time are registered in advance, and these labels are sent, and recorded as environmental condition values at the stage of recording results. You may do it.

  FIG. 7 shows an example of an environmental condition registration display screen 90 for setting an operating state unique to a prosumer among such environmental conditions. In the example of the environmental condition registration display screen 90 shown in FIG. 7, tabs are set for existing and new installations. In the case of the existing tab, keywords relating to tasks specific to the prosumer are set and instructed. The distinction is displayed so that it can be added or deleted.

  In addition, the screen example 90 is configured to set the identification keyword of the consumer business. For the business identification keyword, the screen configuration assumes that a plurality of sets are registered. Combinations of the amount and duration of one or more energy services requested by one or more energy service users may be classified and used.

  In addition, among the data stored in the allowable condition database 114 in the aggregator system 110, the individual evaluation index KPI causes the display unit 123 to display options assumed by the aggregator system 110 in advance, and the prosumer selects from the input unit 125. Alternatively, it may be determined.

FIG. 5 is an example of an individual evaluation index KPI setting screen 91 displayed on the display unit 123. On the individual evaluation index KPI registration screen 91 in FIG. 5, for example, temperature, humidity, CO ₂ concentration, illuminance, etc. are typically displayed as examples of the individual evaluation index KPI. And select and display them as appropriate. In the example shown, this prosumer
The CO ₂ concentration has selected not to use as an individual evaluation index KPI. Furthermore, whether or not to use positioning information (position information) at the time of data measurement is set. For example, it is possible to set the four corners of the room and determine that the data measured in that range is valid. The present embodiment, as can be set for a plurality of areas, and the temperature corresponding to a different area in the "new" tab, humidity, CO ₂ concentration, intensity, such as can define a location information screen. The screen example in FIG. 5 indicates that the SoC of the storage battery, the remaining hot water amount of the water heater, and the like are assumed and proposed as the optional individual evaluation index KPI for the prosumer.

  FIG. 6 is a diagram illustrating an example of a method of extracting the individual evaluation index KPI from the external information service 150 of FIG. 1 on the display screen 92 of the display unit 123. A state is shown in which a part as an individual evaluation index KPI is selected from a hard copy of an arbitrary screen. The predicted value and the actual value are displayed from the aggregator system 110 on the display screen 92 of the display unit 123 attached to the terminal device 121 of the prosumer system 120 with the screen hard copy of the external information service 150 pasted. The input unit 125 performs an operation of selecting a part where the part is located, and character recognition of the position is performed, thereby taking in the data of the target individual evaluation index KPI. Also, a homepage may be used instead of a screen hard copy. In such a case, the value of the tag in the vicinity of the selected position is fetched, and the fetched value is displayed and checked so that the tag value recording the individual evaluation index KPI value can be determined. Can be identified. In particular, with regard to the predicted value, it is necessary to specify at what point in the future the information that can be obtained in this way is information. For this purpose, a position on the screen at which the information indicating the value is displayed may be designated by the same method, and the value may be taken out and confirmed by the prosumer. Such processing should be performed only when the information service provider permits.

  Further, a questionnaire result by a person related to the prosumer may be used as the individual evaluation index KPI. The questionnaire includes, for example, a method of quantifying a questionnaire result of an item such as "comfortable, not feeling anything, a little uncomfortable and very uncomfortable" in the comfort of air conditioning. If energy resources are controlled such as changing the number and speed of the elevators, a questionnaire such as "Is the waiting time long, normal, or coming soon?"

  The allowable values registered in the allowable condition database 114 in FIG. 1 are at least one or more classes, and within the range of the allowable values, the price is uniquely determined from the amount of power generation adjustment or demand adjustment and the duration. Is modeled as follows. Since the price is determined by the contract between the aggregator and the prosumer, any calculation model may be used.For example, it is also possible to use a pay-as-you-go system for a value determined by the product of the amount of generated power adjustment or demand adjustment and the duration. good. Such models include, for example, meter-based lighting rates. In the present invention, once the amount of power generation adjustment or demand adjustment, such as the unit price of the usage-based fee, and the duration are determined, the range of allowable values for which the price can be uniquely calculated is regarded as a class of allowable values.

  The planning unit 113 in the aggregator-side system 110 in FIG. 1 uses the prosumer-specific resource model 111 to increase and decrease the amount of power or demand, which is the technical requirement of the energy service requested by the energy service provider, and start the same. Plan the amount, start time, and duration of resource services for each consumer so that the time and duration are satisfied and the procurement price is low.

  At the time of planning in the planning unit, the supply amount of the resource service is planned within the range of the individual evaluation index KPI permissible value corresponding to the environmental condition value in consideration of the environmental condition of each consumer. Environmental condition values used for planning are forecast values of weather service and electricity price prediction service, calendar information, keywords related to prosumer-specific tasks input by prosumers, if the prosumer side system can communicate with external information service 150, It is better to use information.

  As a specific planning method, the total price of the resource service required for each consumer is minimized, the technical requirements of the energy service (the amount of power generation adjustment or the amount of demand adjustment, start time, duration), and the allowable conditions of each consumer It may be implemented as a planning problem of resource service requirements (generated power adjustment amount or demand adjustment amount, start time, and duration) for the prosumer satisfying the above.

  For example, of the requirements of the resource service, the start time and the duration can be solved by discretizing the start time and the duration and formulating it as a mixed integer programming problem.

  In the planner 113, minimization is desirable, but it is not necessary to limit the solution to an exact minimum solution. In such a case, it is possible to formulate and solve various combinatorial optimization problems by similarly discretizing the time and also discretizing the generated power adjustment amount and the demand adjustment amount. For example, a method such as a genetic algorithm or a particle swarm optimization method can be used.

  The planning result information S4 for each energy resource 131 on the prosumer side determined by the planning unit 113 is transmitted to the communication unit 132 of the energy resource 131 on the prosumer side as the planning result information S4a via the communication unit 112 or in FIG. Is transmitted to the communication unit 122 of the terminal device 121 as the planning result information S4b. In the case of FIG. 2, it is transmitted as plan result information S4 to the communication unit 222 of the terminal device 121 of the prosumer.

  Thereafter, in the case of FIG. 1, the control of the generated power adjustment amount and the demand adjustment amount specified at the specified time is executed in the energy resource 131 in accordance with the plan result information S4b for each energy resource 131 received by the communication unit 132. . In the case of FIG. 2 thereafter, the planning result information S4 for each energy resource 131 received by the communication unit 222 is transmitted to the energy resource 131, and control of the generated power adjustment amount and the demand adjustment amount specified at the specified time is performed. In the energy resource 131. Alternatively, in FIGS. 1 and 2, the operator M confirms the contents by displaying the plan result information S4a and S4 on the display unit 123 of the terminal device 121.

  Thus, the prosumer-side system 120 controls the energy resource 131 in accordance with the received plan result information S4 or S4a for each energy resource 131, performs power generation adjustment or demand adjustment, and supplies an energy service to the power system 190 as a whole prosumer. I do.

  The control result information (S5a and S5b in FIG. 1 and S5 in FIG. 2) of the energy resource 131 is transmitted from the prosumer system 120 to the communication unit 112 of the aggregator system 110 via the communication unit 132, 122, or 222. Sent.

In the present invention, the control result information (S5a in FIG. 1, S5 in FIG. 2) from the terminal device 121 includes not only the execution of the control operation, the set value for the device, and the like, but also The individual evaluation index KPI value before and after the control is executed or during the control is included. The individual evaluation index KPI value may include, for example, a questionnaire result such as indoor temperature and humidity, illuminance, indoor CO ₂ concentration, or satisfaction, a remaining amount of energy storage equipment, and a waiting time for an elevator. It is assumed that at least one of these includes a measurement result or an input result of a value before, during, or after the execution of the resource service.

  As described above, when returning the control result information S5aa or S5 from the terminal device 121 of the prosumer-side system 120 to the aggregator-side system 110, the return is performed in a format including the individual evaluation index KPI value measured by the prosumer-side system 120. I have. These reply processes are performed in the terminal device 121.

  As the terminal device 121, a personal computer, a mobile phone, a tablet terminal, a smartphone, a wearable terminal, or the like can be used. When acquiring the state before and after the resource service through the questionnaire, the terminal device 121 uses the display unit 123 and the input unit 125 to display the question items and take in the answers. In the case of a terminal having a positioning unit 126 for acquiring position information, positioning information can be included in the result. For example, the validity of the result can be determined by determining whether the measured value is an individual environment value measured in a space indicated by the positioning data measured to determine the supply range of the energy resource 131 in advance, or another value. Further, by comparing the positioning result of the position of the energy resource 131 previously measured with the positioning result accompanying the measurement data, for example, the average value of the target range is estimated in a form proportional to the square or the cube of the distance. May be performed. In addition, by fitting the data to a plane represented by a quadratic function or a cubic function in a two-dimensional space or a three-dimensional space with a least square error, the influence on an unmeasured part can be estimated. It is possible to increase the number of factors for determining whether to change the allowable value of the index KPI.

  When the control result information S5a, S5 is returned from the prosumer system 120 to the aggregator system 110, a reply including the individual evaluation index KPI value measured by the prosumer system 120 is sent, so that the The amount of information stored in the allowable condition database 114 includes past experience values, and data is enriched with driving experience. In addition, the prosumer-side resource model 111 can also evolve to reflect a more realistic state of the energy resource 131 by reflecting past driving experience.

  In the aggregator-side system 110, a clearing unit (not shown), a resource service record from a fixed date and time to a fixed date and time stored in a record unit (not shown), and a charge specified in the above-mentioned allowable condition. Based on, calculate the payment amount to the prosumer side. The result recording unit records the environmental condition values in addition to the amount, duration, and start time of the resource service.

  For example, when presenting the fee settlement information to the prosumer, the system contribution result of the plan result is presented for each allowable condition, and a change in the allowable value for the allowable condition is received. Also, when presenting the system contribution results for each allowable condition, the results for the plan value of the individual evaluation index KPI may be displayed.

  In order to ensure the accuracy, the prosumer i, the energy service j, the time zone including the start time and the duration are tr, and the energy service j is the resource service provided by the prosumer i in the time zone tr, RS (i, j, tr), the adjustment amount is Ars (i, j, tr), and the resource service duration in the time zone tr is Drs (i, j, tr), the system contribution of RS (i, j, tr) is , And the unit price of the energy service P (j, tr), for example, as in equation (1).

  When a resource service at a certain start time provides services over a plurality of time zones with different energy service unit prices in view of the duration time, each of the energy services with different unit prices is calculated according to equation (1). Contributions may be sought and calculated as their sum.

  From the generated power adjustment amount or the demand adjustment amount A (j, tr) provided during the time zone tr as the energy service j and the duration D (j, tr), for example, the supply power of the energy service as in equation (2) Calculate the amount.

Also, it is converted into a CO ₂ reduction amount converted from the CO ₂ intensity unit U (tr) of the system power in the time zone and the supplied power amount, a CO ₂ intensity unit of the startup avoidance power source estimated based on the power ratio, and the like. Then, it may be calculated and shown as in equation (3). Start avoid power able to accurately grasp the CO ₂ per unit of sometimes difficult as aggregators, but as generally shown for aging thermal power as operation at one time after the peak demand period and natural disasters The conversion may be performed using the value.

Here, the description has been made assuming that the CO ₂ intensity is the same as the supply time period of the resource service. However, as another case, a case of a service to avoid the suppression of renewable energy is considered. It is necessary to suppress renewable energy only when the output of renewable energy is large, even if the output of a power supply that can perform load-following operation corresponding to the fluctuation of renewable energy is suppressed to the minimum output during the time period. Is greater than demand. In such a situation, increasing the load instead of suppressing the renewable energy is an increase in demand by the suppression avoidance service, that is, an increasing demand response DR. When the energy stored in a storage battery or heat storage tank is used as a demand response DR means, it can also be used to reduce the load in another time zone, so use the basic unit of the normal energy storage operation time zone in that time zone and increase it. If neither the demand response DR nor the suppression is performed, a virtual evaluation such as a generator start / stop cost which is theoretically necessary may be used.

  It should be noted that, in the cost settlement and the presentation of the system contribution results, since the environmental condition is uniquely determined by specifying the time zone tr, it is not necessary to consider the class division of the environmental condition in the evaluation of the effect. In order to allow the operator to reconsider the permissible values, the system contributions obtained by the equations (1) and (3) are summarized for each class of environmental conditions and shown for each class. Here, in the aggregation, for example, the ratio of the contribution to the whole as in the expression (1) may be represented by an average value, and in the case of the expression (3), an integrated value may be represented.

  For the user of the prosumer system, the system contribution calculated for each class of such environmental conditions is sorted in descending order of the contribution, and the allowable value of the individual evaluation index KPI specified for the class is calculated. Also shown. The operator of the prosumer-side system 120 may be made to select the environmental condition items in advance, and systematic contributions may be aggregated and shown to the operator regarding the class division of the selected environmental condition items. By doing so, the operator of the prosumer-side system 120 can grasp its own system contribution to environmental conditions of interest, so that the permissible value of the individual evaluation index KPI can be easily reviewed.

  In a configuration that enables communication with the external information service 150, the prosumer can collect environmental information that cannot be measured by itself. For example, when the prosumer is an agricultural company, the information is a contracted agricultural weather information. As described above, the environmental information corresponds to the time zone tr as a result in a one-to-one correspondence, but is not managed in the form of the contribution to the time zone, but is managed as the contribution to each category of the environmental information value. There is also an effect that local environmental conditions in a region where the prosumer system 120 exists can be easily considered.

  In order to provide such information 170, information necessary for presentation to the aggregator system 110 is calculated in advance and stored in a database (not shown) of the aggregator system 110, or a request from the prosumer system 120. When there is, it is necessary to search the actual data and calculate the result. In the case of transmission along with the provision of the settlement information, the calculation may be performed before the transmission, and the display data may be generated together with the display data creation of the settlement data.

  The embodiment in which the contribution degree is sorted in descending order is as described above, but other than that, the indication may be ascending order. In this way, it is possible to grasp the environmental conditions in which the user himself / herself has not contributed well, and to consider the improvement of the resource operation of the prosumer himself and to improve the amount of resource service provided thereby.

  The system contribution by other prosumers may be shown together with statistical processing such as average and variance. At this time, the statistical processing may be limited to the prosumers having common characteristics with the counterpart prosumers, such as the type of prosumers, from the contract information. By doing so, it becomes possible to determine whether or not the prosumer can be improved as compared with others.

  Regarding the performance of the individual evaluation index KPI, not only the data of the target prosumer itself but also information of other prosumers having similar attributes are displayed, so that the actual value of the individual evaluation index KPI can be changed by changing the allowable value of the individual evaluation index KPI. Since it is easy to determine how much the possibility is changed, the possibility that the allowable value of the individual evaluation index KPI that affects the resource supply amount is changed is increased.

  Second Embodiment A second embodiment of the present invention will be described with reference to FIG. The third embodiment does not use the prosumer-specific resource model 111 or the allowable condition database 114 in the first embodiment, and enables the prosumer, which is the object of the present invention, to participate in determining the supply amount of the energy service according to the common environment. It is.

  Hereinafter, only the portions that are different from the first embodiment will be described. The aggregator-side system 110 in FIG. 3 includes a planning unit 113, a performance database 311 and a communication unit 112. The planning unit 113 plans an aggregation based on information (not shown), that is, information on the basic specifications and charges of the resource such as the equipment rated capacity of the energy resource 131 in the prosumer system 120.

  The plan result information S4 for each prosumer is transmitted to the communication unit 132 and the communication unit 122 as plan result information S4b and plan result information S4c, respectively. Here, the plan result information S4b transmitted to the communication unit 132 and the subsequent response of each unit are the same as those in the first embodiment, and thus description thereof is omitted.

  The second embodiment of the present invention is characterized in the plan result information S4c transmitted to the communication unit 122. The plan result information S4c is composed of a plurality of types of information. The first is the plan result information S4a having the same contents as in the first embodiment (demand adjustment amount and generated power adjustment amount for each time). The second is actual information S4c1 of the individual evaluation index KPI value, or more preferably, system contribution information S4c2. Here, the actual information S4c1 of the individual evaluation index KPI value is a past actual value of the individual evaluation index KPI value that will be changed as a result of controlling the energy resource according to the plan result information S4a, or is assumed based on the past actual result. Value.

  In the case of the second embodiment, the aggregator-side system 110 presents the plan result information S4c to the prosumer-side system 120 and obtains the confirmation information S5c from the prosumer-side system 120 before the provision start time of the energy service. Therefore, the confirmation information S5c means that the individual evaluation index KPI has been approved including how the KPI value is changed when the control is executed. Here, the plan result information S4a included in the presented plan result information S4c sets the timing in the same manner as the gate closing used in power trading, for example, until noon on the previous day or one hour before the implementation, and adjusts to that point. It is the content of doing.

  At this time, in the second embodiment, the plan result in the class division to which the expected value of the environmental condition at the time of planning belongs and the actual information S4c1 of the individual evaluation index KPI value are also provided together with the plan result information S4a. By doing so, the prosumer can grasp the influence on the individual environment when the plan result information S4a is followed and the expected value of the environmental condition presupposed in the plan, so that the approval decision is facilitated. . In particular, in the case of a keyword related to a business specific to a prosumer, if the prosumer's assumption is different, a procedure of correcting and recalculating may be added. Thus, at the time of presenting the plan, it is necessary to provide a means and a procedure for inputting a correction instruction from the prosumer when there is a difference between the aggregator's prediction regarding the environmental condition value and the prosumer's prediction as well as the approval / denial. Thus, the prosumer can be more involved in determining the supply of energy services according to the common environment than in the case of approving / denying.

  Further, the system contribution degree information S4c2 may be provided together with the plan result information S4a. This makes it possible to make an approval decision according to the status of the system.

  Further, in addition to the correction input from the prosumer for the expected difference of the common environment value from the aggregator, the prosumer can input an instruction to increase or decrease the allowable value of the expected individual evaluation index KPI value, The aggregator may replan accordingly.

  For this purpose, for example, when the performance of the individual evaluation index KPI in the predicted environmental condition category is displayed on the display unit 123 in the prosumer, an up button and a down button are added to the screen display, and 1% of the button is displayed. Alternatively, a change in the allowable value of the individual evaluation index KPI may be input in the form of 3%. When the input unit 125 in the prosumer is a touch screen, a swipe operation may be used, and the change amount may be determined based on the speed of the operation input. The result of the operation input may be displayed on the display unit 123 of the terminal device 121 and checked.

  In response to this result, the planning unit 113 of the aggregator-side system 110 changes the supply amount of the energy resource 131 of the prosumer in the vicinity of the current plan value, and not only the designated individual evaluation index KPI value but also other individual The sensitivity to the evaluation index KPI value is also calculated. The sensitivity is a change amount of the individual evaluation index KPI value with respect to a change amount of the energy resource supply amount, and may be simply obtained by dividing a change amount of the individual evaluation index KPI value by a change amount of the energy resource supply amount. A change amount of the energy resource supply amount corresponding to the increase amount or the decrease amount of the set individual evaluation index KPI is calculated from the sensitivity of the individual evaluation index KPI value, and the calculated value is compared with another individual evaluation index KPI value. Is calculated and presented to the prosumer.

  The prosumer is presented again with the result, that is, the energy resource supply amount in consideration of the increase or decrease from the initial energy resource supply amount and the individual evaluation index KPI value changed by the increase / decrease, and the re-presented information. May be input for approval / denial.

  Also, instead of accepting the correction result and calculating the sensitivity in the planning unit 113 of the aggregator-side system 110, the sensitivity to each individual evaluation index KPI value in the vicinity of the energy resource supply amount that is the planning result at the time of the first planning is calculated. In advance, in response to an operation on the terminal device 121 of the prosumer-side system 120, a change amount of the energy resource supply amount and a change amount of another individual evaluation index KPI value are calculated and displayed on the display device 123. Is also good. Since the communication processing and the like can be omitted as compared with the case where the calculation is performed by the planning unit 113 of the aggregator-side system 110, the prosumer can determine the correction to the plan more quickly.

  On the other hand, the scheme implemented by the planning unit 113 of the aggregator-side system 110 can cope with a change in sensitivity due to a change in the plan. It becomes possible.

  The result measured by the individual evaluation index KPI measurement unit 124 of the prosumer system 120 is transmitted to the aggregator system as S5c, received by the communication unit 112, and recorded in the performance database 311.

  In the third embodiment, the aggregator system of the first and second embodiments is configured to be executed by a plurality of servers. By doing so, it is possible to make the planned time and the data recording capacity less susceptible to an increase in the number of prosumers and energy services. The following describes the flow of the processing for that. The drawing is omitted because it is a simple flow.

  First, a request from the energy service user side system is divided according to the number of aggregator side systems (step 1). Group the prosumer systems according to the number of aggregator systems (step 2). The request divided in step 1 to each aggregator system is planned to be realized by the resources of the consumer system divided in step 2 (step 3).

  In this way, planning can be performed by a plurality of servers. The division of the prosumer may be arbitrary. For example, as shown in FIG. 4, when the request 410 from the energy service user system 160 is planned by four servers, the request 410 is almost equal in size to the request 411. , 412, 413, and 414, and from the individual evaluation index KPI permissible value for the class value of the environmental condition related to the request, the adjustment amount and the duration of the power or demand obtained using the prosumer-specific resource model 111 are calculated. What is necessary is just to divide so that the product of the amount or the adjustment amount and the measurement time is equalized.

  Although the request 410 is disassembled in FIG. 4 as an example, the request 410 may be divided in the time direction or divided so that the supply amounts allocated to all servers are almost equal as illustrated in FIG. You don't have to. If there is a difference in the capabilities of the servers, the ratio may be set according to the capabilities.
