Abstract

A server is a server of an aggregator that requests a power-conditioning resource to participate in demand response for adjusting electric power demand-supply balance in a power grid. The power-conditioning resource includes a plurality of vehicles that is managed by a provider and used to provide a service thereof. The server includes a storage device and a processing device. The storage device is configured to store collection result information indicating results of participation of the vehicles in the demand response in a predetermined collection period. The processing device is configured to set an evaluation value indicating a degree of contribution of the provider to adjustment of electric power demand-supply balance based on the collection result information.

First claim

What is claimed is:

1 . A server of an aggregator that requests a power-conditioning resource to participate in demand response for adjusting electric power demand-supply balance in a power grid,
wherein the power-conditioning resource includes a plurality of provider vehicles that is managed by a vehicle service provider and that is used to provide a service thereof, and wherein the server comprises:
a storage device configured to store collection result information indicating results of participation of the plurality of provider vehicles in the demand response in a predetermined collection period; and
a processing device configured to set an evaluation value indicating a degree of contribution of the vehicle service provider to the adjustment of electric power demand-supply balance based on the collection result information,
wherein the power-conditioning resource includes a participation-scheduled vehicle other than the plurality of provider vehicles, wherein the participation-scheduled vehicle is a vehicle that is scheduled to participate in the demand response using an electric power facility connected to the power grid, wherein the server further comprises a communication device configured to acquire position information indicating a location of the participation-scheduled vehicle, and wherein the processing device is configured to:
predict whether the participation-scheduled vehicle is able to reach the electric power facility at a start time of the demand response based on the position information;
generate a request signal for requesting a target vehicle which is able to participate in the demand response out of the plurality of provider vehicles to participate in the demand response instead of the participation-scheduled vehicle when it is predicted that the participation-scheduled vehicle is not able to reach the electric power facility at the start time; and
set the evaluation value to be higher when the target vehicle participates in the demand response in response to the request signal.

2 . The server according to claim 1 , wherein each of the plurality of provider vehicles is configured to participate in the demand response using the electric power facility connected to the power grid, and
wherein the evaluation value is determined based on a total amount of electric power transmitted between the plurality of provider vehicles and the electric power facility for participation in the demand response in the collection period.

3 . The server according to claim 1 , wherein the evaluation value is determined based on a total number of times the plurality of provider vehicles has participated in the demand response in the collection period.

4 . The server according to claim 1 , wherein the evaluation value is determined based on a total length of periods in which the plurality of provider vehicles has participated in the demand response in the collection period.

5 . The server according to claim 1 , wherein each of the plurality of provider vehicles is configured to participate in the demand response by receiving electric power supplied from the electric power facility connected to the power grid, and
wherein the processing device is configured to:
set a command value for the supplied electric power; and
set the command value to be greater when the evaluation is high than when the evaluation value is low.

6 . The server according to claim 1 , wherein the vehicle service provider includes a vehicle rental service provider or a car-sharing service provider.

7 . A power conditioning system comprising:
the server of the aggregator according to claim 1 ; and a power company server configured to request the server of the aggregator to adjust electric power demand-supply balance, wherein the power company server is configured to set an electricity rate of the vehicle service provider to be lower when the evaluation value is high than when the evaluation value is low.

8 . A server of an aggregator that requests a power-conditioning resource to participate in demand response for adjusting electric power demand-supply balance in a power grid,
wherein the power-conditioning resource includes a plurality of provider vehicles that is managed by a vehicle service provider and that is used to provide a service thereof, and wherein the server comprises:
a storage device configured to store collection result information indicating results of participation of the plurality of provider vehicles in the demand response in a predetermined collection period; and
a processing device configured to set an evaluation value indicating a degree of contribution of the vehicle service provider to the adjustment of electric power demand-supply balance based on the collection result information,
wherein the power-conditioning resource includes a participation-scheduled vehicle other than the plurality of provider vehicles, wherein the participation-scheduled vehicle is a vehicle that is scheduled to participate in the demand response, wherein the server further comprises a communication device configured to acquire a replacement request from the participation-scheduled vehicle, wherein the replacement request is a signal for requesting the power-conditioning resource instead of the participation-scheduled vehicle to participate in the demand response, and wherein, when the communication device receives the replacement request, the processing device is configured to:
generate a request signal for requesting a target vehicle which is able to participate in the demand response out of the plurality of provider vehicles to participate in the demand response instead of the participation-scheduled vehicle; and
set the evaluation value to be higher when the target vehicle participates in the demand response in response to the request signal.
