PROBLEM TO BE SOLVED: To provide a technique to efficiently use an accumulator capable of providing an ancillary service and feeding power supply to a load in a facility.SOLUTION: An accumulator 10 is capable of charging from a power system 50, discharging to the power system 50, and discharging to a load 152. An appropriate value determining unit 24 determines an appropriate value of the SOC (state of charge) of the accumulator 10 taking into account both a first mode in which charging or discharging is performed between the power system 50 and the accumulator 10 in response to a command from the operating agent of the power system 50, and a second mode in which power is supplied to the load 152. A charge/discharge control unit 25 charges or discharges the accumulator 10 such that the SOC of the accumulator 10 approaches the appropriate value determined by the appropriate value determining unit 24. |
