A power supply system in which a lead storage cell is used, wherein stable and highly efficient control is performed in consideration of the properties of the lead storage cell and the supply-demand balance. A lead storage cell (320) stores power generated by a distributed power source (310) and power received from a power system. An energy management system (EMS) (100) forecasts the amount of power generated by the distributed power source (310) and the amount of power demanded by load devices (400-600), and correspondingly calculates a target value for the operation voltage of the lead storage cell (320). A power conditioning system (PCS) (300) controls the input/output of power with respect to the distributed power supply (310) and the lead storage cell (320) so that the operation voltage of the lead storage cell (320) reaches the target value calculated by the EMS (100). |
