Abstract

A server includes a processor and a communication device configured to acquire a transmitted power amount transmitted from a power facility during external charging of a vehicle participating in a DR. The processor is configured to calculate, when a plurality of vehicles participates in the DR, a standard reward that is a standard of a reward given from an aggregator to each of the vehicles, according to the transmitted power amount, decide, when a first vehicle participates in the DR, a first reward that is a reward given from the aggregator to the first vehicle, such that the first reward becomes the standard reward for the first vehicle, and decide, when a second vehicle participates in the DR, a second reward that is a reward given from the aggregator to the second vehicle, such that the second reward becomes higher than the standard reward for the second vehicle.

First claim

What is claimed is:

1 . A server of an aggregator configured to request a plurality of vehicles to participate in a demand response (DR), each of the vehicles being equipped with a power accumulation device and configured to be electrically connectable to a power system, the server comprising:
a communication device configured to acquire a transmitted power amount that is transmitted from a power facility during external charging of a vehicle participating in the DR, the external charging being charging of the power accumulation device using power from the power facility connected to the power system; and a processor configured to:
calculate, when the vehicles configured to participate in the DR by executing the external charging participate in the DR, a standard reward that is a standard of a reward given from the aggregator to each of the vehicles, according to the transmitted power amount;
decide, when a first vehicle from among the vehicles participates in the DR, a first reward that is a reward given from the aggregator to the first vehicle, such that the first reward becomes the standard reward for the first vehicle; and
decide, when a second vehicle from among the vehicles participates in the DR, a second reward that is a reward given from the aggregator to the second vehicle, such that the second reward becomes higher than the standard reward for the second vehicle, wherein:
the first vehicle is configured to execute wired charging that is the external charging using power received via a power cable of a first power facility as the power facility; and the second vehicle is configured to execute wireless charging that is the external charging using power received from a second power facility as the power facility in a wireless manner.

2 . The server according to claim 1 , wherein the processor is configured to:
decide the first reward according to a first transmitted power amount that is a transmitted power amount for the first vehicle, and a first unit price that is a unit price of the first reward for the first transmitted power amount; and decide the second reward according to a second transmitted power amount that is a transmitted power amount for the second vehicle, and a second unit price that is a unit price of the second reward for the second transmitted power amount, the second unit price being higher than the first unit price.

3 . The server according to claim 2 , wherein the processor is configured to:
calculate a first power cost that is a power cost of the first vehicle in the DR, according to a power rate unit price of the power system and the first transmitted power amount; calculate a second power cost that is a power cost of the second vehicle in the DR, according to the power rate unit price and the second transmitted power amount; calculate a first profit that is a profit obtained when the first vehicle participates in the DR, by subtracting the first power cost from the first reward; calculate a second profit that is a profit obtained when the second vehicle participates in the DR, by subtracting the second power cost from the second reward; and decide the first reward and the second reward such that a difference between the first profit and the second profit becomes lower than a threshold value.

4 . The server according to claim 1 , wherein:
a total reward amount that is a sum of a reward given from the aggregator to the vehicles, is an integrated value of a sum of the first reward for at least one first vehicle and a sum of the second reward for at least one second vehicle; and the processor is configured to decide the first reward and the second reward such that the total reward amount is maintained.

5 . The server according to claim 1 , wherein the processor is configured to, when the first vehicle and the second vehicle use paid infrastructure, decide the first reward and the second reward such that the second vehicle uses the paid infrastructure at a cheaper usage fee than the first vehicle.

6 . The server according to claim 1 , wherein:
the wireless charging includes charging during traveling that is executed while the second vehicle is traveling in a power supply lane in which the second power facility is provided; the processor is configured to, in a case where the second vehicle participates in the DR by executing the charging during traveling, execute processing for sending a notification to a user of the second vehicle when a start time of a period in which the second vehicle participates in the DR arrives; and the notification includes a notification prompting the user of the second vehicle such that the second vehicle travels in the power supply lane when the second vehicle is traveling in a traveling lane different from the power supply lane at the start time.

7 . The server according to claim 1 , wherein:
each of the vehicles is configured to participate in the DR by executing an external power supply for supplying power accumulated in the power accumulation device to the power facility; the first vehicle is configured to execute a wired power supply that is the external power supply for supplying power to the first power facility via the power cable; the second vehicle is configured to execute a wireless power supply that is the external power supply for supplying power to the second power facility in the wireless manner; the communication device is configured to acquire a received power amount received by the power facility during the external power supply of the vehicle participating in the DR; and the processor is configured to:
calculate, when each of the vehicles participates in the DR, the standard reward according to the received power amount;
decide, when the first vehicle participates in the DR, the first reward that is calculated according to the received power amount of the first power facility, such that the first reward becomes the standard reward for the first vehicle; and
decide, when the second vehicle participates in the DR, the second reward that is calculated according to the received power amount of the second power facility, such that the second reward becomes higher than the standard reward for the second vehicle.
