POWER SYSTEM

摘要

[PROBLEMS] To provide a power system constituted by interconnecting a plurality of power consumers through a power demand control apparatus and capable not only of self-sustaining operation without relying upon conventional power system but also of coexisting with conventional power system. [MEANS FOR SOLVING PROBLEMS] A plurality of power consumers each equipped with a power generation apparatus (101), a power storage apparatus (102) and a plurality of loads (103), and a power demand control apparatus (104) are interconnected through a power demand line (W). A power demand control apparatus (51) makes a decision whether power deficiency or surplus power occurs in a power consumer (11) equipped with the power demand control apparatus (51) based on data about the total electric energy, maximum power demand, and total power demand of each power consumer in tomorrow predicted by a neural network and controls the operation to receive power from other power consumer (12-15) equipped with a power generation apparatus (101, 151) and/or a power storage apparatus (102, 152) if power deficiency occurs in the power consumer (11), and to deliver power to other power consumer (12-15) if surplus power is generated in the power consumer (11).
