    • 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 1a 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 1b through 1e 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 1b through 1e to suppress their outputs and store surplus power into storage batteries 8. The plurality of dispersed power sources 1a through 1e can be thus made to impartially suppress the outputs, so that the capacity of the storage batteries 8 can be reduced.
    • 关于与商用电力系统的高压 - 低压变压器连接的多个分散电源的输出抑制控制,消除了多个分散电源的输出抑制的偏向性,并且成本增加 防止分散的电源。 如果分散电源1a的受电点的电压超过适当值的上限,则功率调节器4抑制对受电点的输出,以将剩余电力存储到蓄电池8中,并且发送 输出抑制开始信号发送到管理单元9。 管理单元9将输出抑制命令信号发送到其他分散电源1b至1e,其中电力接收点处的电压不超过适当值的上限,以使其他分散电源1b通过 1 e以抑制其输出并将剩余电力存储到蓄电池8中。 因此,可以使多个分散电源1a至1e公正地抑制输出,从而可以减小蓄电池8的容量。
