1. A server configured to manage a plurality of vehicles, each of the vehicles including a power storage device and a switching device openable and closable to switch electrical connection between the power storage device and a power grid, each of the vehicles being configured to receive electric power from the power grid through power equipment outside the vehicle when the switching device is in a closed state, the server comprising a processing device configured to:
acquire, for each of the vehicles, information on whether the switching device is in an open state or the closed state;
set priority levels for the vehicles, the processing device being configured to set a priority level of a first vehicle in which the switching device is in the closed state among the vehicles to be higher than a priority level of a second vehicle in which the switching device is in the open state among the vehicles;
select, based on the priority levels, a participating vehicle to be used for demand-increasing demand response for increasing a power load in the power grid from among the vehicles;
select the vehicle having the highest priority level among the vehicles as the participating vehicle;
transmit, to the participating vehicle, a signal for notification that the vehicle having the highest priority level has been selected as the participating vehicle;
acquire a target power consumption;
determine whether a total demand response (DR) amount of the participating vehicle achieves the target power consumption; and
in a case where the participating vehicle does not achieve the target power consumption, select a vehicle having the second highest priority level from among the vehicles as the participating vehicle.
