Abstract

A first profile of each of resources in which information about characteristics of the resources when creating negawatts by controlling operation of the resources and decreasing electric power consumption of the resources or creating posiwatts by increasing the electric power consumption of the resources, and information about contract content between an aggregator and a relevant consumer are described, and a first control scenario for each electric power trading form in which control content of the resources to decrease the electric power consumption is described are stored; a resource group composed of a plurality of resources is generated by combining the resources so that the negawatts or posiwatts which satisfy conditions of a trading target electric power product can be created, on the basis of the first profile of each resource; a control scenario is selected; and each of the resources constituting the generated resource group is controlled accordingly.

First claim

1 . An electric power creation control system for creating electric power by controlling operation of resources equipment of each consumer who has made a contract with an aggregator, the electric power creation control system comprising:
a storage device that stores a first profile of each of the resources, in which information about characteristics of the resources when creating negawatts by decreasing electric power consumption of the resources or creating posiwatts by increasing the electric power consumption of the resources, and information about contract content between the aggregator and the relevant consumer are described, and a control scenario for each electric power trading form in which control content of the resources to decrease or increase the electric power consumption is described; a resource group generation unit that generates a resource group composed of the plurality of resources by combining the resources so that the negawatts or posiwatts which satisfy conditions of a trading target electric power product can be created, on the basis of the profile of each resource; a control scenario selection unit that selects the first control scenario corresponding to the trading form of the electric power product; and a control unit that controls each of the resources constituting the resource group generated by the resource group generation unit in accordance with the control scenario selected by the control scenario selection unit; wherein the conditions of the electric power product include at least: a quantity that is electric energy of the electric power product; start time of a time slot to sell the electric power product; and a lamp period that is a period of time from the start time until the electric enemy reaches the quantity; wherein the profile describes the lamp period which is a period of time from the electric power consumption actually starts to decrease or increase until a decreased amount or an increased amount of the electric power consumption reaches a target value; and wherein the resource group generation unit generates the resource group based on the profile of each of the resources.

2 . The electric power creation control system according to claim 1 , wherein the conditions of the electric power product include: advance notice time is a period of time from the start time until advance notice is made by a buyer of the electric power product before the start timer; and duration of the electric power product;
wherein the profile describes, as further information about the characteristics of the relevant resource, at least lead time which is a period of time from control of operation of the resource is started until the electric power consumption actually starts to decrease or increase, and an assumed controlled variable which is the electric power consumption decreased or increased by operation control of the resource; and wherein the resource group generation unit generates the resource group based on the profile of each of the resources.

3 . The electric power creation control system according to claim 1 , wherein the profile describes, as information about contract content between the aggregator and the relevant consumer, at least a controllable time slot that is a time slot during which the operation of the relevant resource predetermined by the aggregator with the consumer can be controlled, and possible control duration that is a period of time during which the operation of the resource can be continuously controlled; and
wherein the resource group generation unit generates the resource group by combining a plurality of the resources from among the resources, whose operation can be controlled during the time slot of the electric power product, on the basis of the profile of each resource.

4 . The electric power creation control system according to claim 3 , wherein the wherein the profile describes, as information about the contract content between the aggregator and the relevant consumer, a price per unit electric energy to be paid to the consumer for the negawatts or the posiwatts created by the operation control of the relevant resource; and
wherein the resource group generation unit generates the resource group by preferentially combining the resources, regarding which a licensing fee to be paid to the consumer is low, on the basis of the profile of each resource whose operation can be controlled during the time slot of the electric power product.

5 . The electric power creation control system according to claim 4 ,
wherein the control unit: calculates total quantity of the negawatts then created on the basis of the electric enemy of the negawatts created by the operation control which is transmitted respectively from each resource whose operation is controlled in accordance with the control scenario; compares the calculated total quantity of the negawatts with the electric energy of the electric power product; calculates an excessive amount or insufficient amount of the electric energy when it is determined that the total quantity of the then created negawatts does not match the electric energy of the electric power product; and controls the operation of some or all the resources constituting the relevant resource group so that the total quantity of the then created negawatts will be decreased or increased by the calculated excessive amount or insufficient amount of the electric energy.

6 . An electric power creation control method executed at an electric power creation control system for creating electric power by controlling operation of resources of each consumer who has made a contract with an aggregator,
wherein the electric power creation control system includes a storage device that stores a profile of each of the resources, in which information about characteristics of the resources when creating negawatts by decreasing electric power consumption of the resources or creating posiwatts by increasing the electric power consumption of the resources, and information about contract content between the aggregator and the relevant consumer are described, and a control scenario for each electric power trading form in which control content of the resources to decrease or increase the electric power consumption is described, the electric power creation control method comprising: a first step executed by the electric power creation control system generating a resource group composed of the plurality of resources by combining the resources so that the negawatts or posiwatts which satisfy conditions of a trading target electric power product can be created, on the basis of the profile of each resource, and selecting the control scenario corresponding to the trading form of the electric power product; and a second step executed by electric power creation control system controlling each of the resources constituting the generated resource group in accordance with the selected control scenario; wherein the conditions of the electric power product include at least: a quantity that is electric energy of the electric power product; start time of a time slot to sell the electric power product; and a lamp period that is a period of time from the start time until the electric energy reaches the quantity; wherein the profile describes the lamp period which is a period of time from the electric power consumption actually starts to decrease or increase until a decreased amount or an increased amount of the electric power consumption reaches a target value; and wherein in the first step, the electric power creation control system generates the resource group based on the profile of each of the resources.

7 . The electric power creation control method according to claim 6 , wherein the conditions of the electric power product further inclu
