1. A method of controlling a chargeable power amount and a dischargeable power amount in each of charging and discharging apparatuses included in a power transmission and distribution system, wherein:
the power transmission and distribution system includes a power grid and a plurality of charging and discharging apparatuses connected to the power grid;
each of chargers and dischargers of the charging and discharging apparatuses is configured to, when being connected to a storage battery, charge the storage battery with power from the power grid or discharge the storage battery by transferring power to the power grid;
the power transmission and distribution system includes, in each of the charging and discharging apparatuses, a communication unit configured to receive information on a charging requirement amount and a discharging requirement amount of at least one other charging and discharging apparatus; and
the method comprises:
a process for calculating, in each of the charging and discharging apparatuses, according to an average agreement calculation of a multi-agent system having each of the charging and discharging apparatuses as an agent, agreement values obtained by dividing, by the number of agents, a total of charging requirement amounts and a total of discharging requirement amounts of all of the charging and discharging apparatuses connected to the power grid, respectively, using an own charging requirement amount and an own discharging requirement amount and information on the charging requirement amount and the discharging requirement amount of the at least one other charging and discharging apparatus acquired by the communication unit; and
a process for controlling, in each of the charging and discharging apparatuses, a limit amount on a charging execution amount and a limit amount on a discharging execution amount of each of the charging and discharging apparatuses based on the agreement values of the charging requirement amounts and the discharging requirement amounts.
