1. A power management apparatus for managing demand and supply of electric power between a power network and at least one vehicle which is electrically connected to the power network and available as a power adjustment resource for the power network, the at least one vehicle including a fuel cell electric vehicle and a battery electric vehicle, wherein the battery electric vehicle and the fuel cell electric vehicle are selectively electrically connected to the power network, the power management apparatus comprising:
an acquisition unit that
obtains an operation plan of the fuel cell electric vehicle, and
obtains, from the fuel cell electric vehicle, information on a remaining hydrogen level available for the fuel cell electric vehicle;
a determination unit that determines whether the fuel cell electric vehicle is available for a demand response request, based on the operation plan and the remaining hydrogen level information; and
a charging and discharging control unit configured to:
create a power supply schedule for the fuel cell electric vehicle based on the demand response request; and
create a charging and discharging schedule for the battery electric vehicle based on the demand response request,
wherein when the demand response request is a reduce demand request requesting a reduction in electric power demand;
the acquisition unit
obtains an operation plan of the battery electric vehicle, and
obtains, from the battery electric vehicle, SOC information of a power storage mounted on the battery electric vehicle,
the determination unit
calculates a first float indicating an amount of time from a scheduled end time of the operation plan of the fuel cell electric vehicle until an electric power supply start time according to the demand response request,
calculates a second float indicating an amount of time from a scheduled end time of the operation plan of the battery electric vehicle until the electric power supply start time, and
determines a priority of the fuel cell electric vehicle and a priority of the battery electric vehicle which are participating in the demand response request, based on the first float and the second float, wherein a weight of the second float for the priority of the battery electric vehicle is greater than a weight of the first float for the priority of the fuel cell electric vehicle, and
based on the determined priority of the fuel cell electric vehicle and the priority of the battery electric vehicle, the charging and discharging control unit transmits one of:
a fuel-cell-vehicle command to the fuel cell electric vehicle, causing the fuel cell electric vehicle to supply electric power to the power network based on the power supply schedule; or
a battery-vehicle command to the battery electric vehicle, causing the battery electric vehicle to supply power to the power network based on the charging and discharging schedule.
