Abstract
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 sourceexceeds the upper limit of a proper value, then a power conditionersuppresses an output to a power receiving point to store a surplus power into a storage batteryand transmit an output suppression start signal to a management unit. The management unittransmits an output suppression command signal to the other dispersed power sourcesthroughof which the voltage at the power receiving point is not exceeding the upper limit of the proper value to make the other dispersed power sourcesthroughto suppress their outputs and store surplus power into storage batteries. The plurality of dispersed power sourcesthroughcan be thus made to impartially suppress the outputs, so that the capacity of the storage batteriescan be reduced.
