Abstract
A V2G system includes: a power system; a charging/discharging device including an electricity storage unit, a power conversion unit that converts power transferred between the electricity storage unit and the power system, a reception unit, and a control unit that controls an operation of the power conversion unit based on a received signal; and a server device that manages charging and discharging of the electricity storage unit. The server device determines a period of time during which power is discharged from the electricity storage unit to the power system or during which the electricity storage unit is charged using power supplied from the power system, and transmits an instruction including the period of time to the charging/discharging device. The control unit of the charging/discharging device starts up or stop based on the period of time indicated by the instruction from the server device.
