Regarding output suppression control of a plurality of dispersed power sources linked to a high-voltage-to-low-voltage transformer of a commercial power system, the partiality of the output suppression of a plurality of dispersed power sources is eliminated and, cost increase of the dispersed power sources is prevented. If a voltage at a power receiving point of a dispersed power source 1 a exceeds the upper limit of a proper value, then a power conditioner 4 suppresses an output to a power receiving point to store a surplus power into a storage battery 8 and transmit an output suppression start signal to a management unit 9 . The management unit 9 transmits an output suppression command signal to the other dispersed power sources 1 b through 1 e of which the voltage at the power receiving point is not exceeding the upper limit of the proper value to make the other dispersed power sources 1 b through 1 e to suppress their outputs and store surplus power into storage batteries 8 . The plurality of dispersed power sources 1 a through 1 e can be thus made to impartially suppress the outputs, so that the capacity of the storage batteries 8 can be reduced.
