Abstract

A server manages power adjustment resources electrically connected to a power network. The power adjustment resources include power equipment installed in a facility and configured to supply power from a vehicle to the power network and charge power from the power network to the vehicle. When reservation information for using the facility is received from a user, the server predicts a power supply-demand balance in the power network on a reserved date and time of use of the facility. When a DR for adjusting the power supply-demand balance is predicted to be performed on the reserved date and time of use, the server prepares a use plan for the facility so as to include the vehicle participating in the DR using the power equipment. The server gives an incentive to the user when the user accepts the use plan.

First claim

What is claimed is:

1. A server that manages power adjustment resources electrically connected to a power network,
the power adjustment resources including power equipment installed in a facility and configured to be able to supply power from a vehicle to the power network and charge power from the power network to the vehicle, and
the server comprising:
a processor; and
a memory that stores a program that is executable by the processor, wherein the processor executes the program to:
receive use reservation information for use of the facility from a user terminal associated with a user;
transmit, to a second server, a request for a prediction of a power supply-demand balance for a date and time associated with the use reservation information;
receive, from the second server, a predicted power supply-demand balance for the date and time associated with the user reservation information;
prepare a facility use plan based on the predicted power supply-demand balance, the facility use plan including a time band for which participation in a demand response is requested on the date and time associated with the use reservation information, the request for participation in the demand response includes a downward demand response or an upward demand response of a requested power adjustment, a demand response time band including a demand response start time and a demand response end time;
determine whether the date and time associated with the use reservation information includes the demand response time band;
upon determination that the date and time associated with the use reservation information does not include the demand response time band, set an external charge time band for which the vehicle is externally charged;
upon determination that the date and time associated with the use reservation includes the demand response time band, set a demand response participation time band for which the vehicle can participate in the demand response;
give an incentive to the user when the user accepts the use plan; and
control the power equipment in the facility to perform the requested power adjustment according to the use plan.

2. The server according to claim 1 , wherein the processor executes the program to prepare the use plan so as to include information about the time band for which the vehicle participates in the demand response and information about the incentive for such participation.

3. The server according to claim 1 , wherein the processor executes the program to increase the incentive when the vehicle is a rental car compared to when the vehicle is a vehicle owned by the user.

4. The server according to claim 1 , wherein the incentive includes at least one of a bonus about use of the facility, a bonus about use of other facilities around the facility, and a bonus about use of public transportation.

5. The server according to claim 1 , wherein the processor executes the program to:
calculate an amount of power needed for travel of the vehicle from an expected travel distance of the vehicle acquired from the use plan, and
set an amount of power to be supplied from the power network to the vehicle so as to be equal to or more than the calculated amount of power.

6. The server according to claim 5 , wherein when the vehicle participates in the demand response on the reserved date and time of use and the demand response involves power supply from the vehicle to the power network, the processor executes the program to set the amount of power to be supplied from the power network to the vehicle so as to be more than the amount of power needed for travel of the vehicle.

7. The server according to claim 6 , wherein when the demand response involves power supply from the vehicle to the power network, the processor controls the amount of power to be supplied from the vehicle to the power network in such a range that an amount of charge in the vehicle does not fall below the calculated amount of power.

8. A power adjustment system comprising:
power adjustment resources electrically connected to a power network; and
a server that manages the power adjustment resources,
the power adjustment resources including power equipment installed in a facility and configured to be able to supply power from a vehicle to the power network and charge power from the power network to the vehicle, wherein
when an input of reservation information for using the facility is received from a user, the server
transmits, to a second server, a request for a prediction of a power supply-demand balance for a date and time associated with the use reservation information,
receives, from the second server, a predicted power supply-demand balance in the power network on a reserved date and time of use of the facility,
prepares a facility use plan based on the predicted power supply-demand balance, the facility use plan including a time band for which participation in a demand response is requested on the date and time associated with the use reservation information, the request for participation in the demand response includes a downward demand response or an upward demand response of a requested power adjustment, a demand response time band including a demand response start time and a demand response end time,
determines whether the date and time associated with the use reservation information includes the demand response time band,
upon determination that the date and time associated with the use reservation information does not include the demand response time band, sets an external charge time band for which the vehicle is externally charged,
upon determination that the date and time associated with the use reservation includes the demand response time band, sets a demand response participation time band for which the vehicle can participate in the demand response,
gives an incentive to the user when the user accepts the use plan, and
controls the power equipment in the facility to perform the requested power adjustment according to the use plan.
