The purpose of the present invention is to build a system with which efficient operational control among a plurality of distributed power supplies can be managed without undermining versatility of the distributed-power-supply side. Accordingly, a power supply system (100) according to the present invention is provided with a plurality of distributed power supplies which include: an electrical storage battery (1); and a power generation device (13) for generating power during periods in which a first current sensor (11) detects a forward power flow. The power supply system is characterized by being provided with: an interconnected-operation switch (8) which is closed during interconnected operation such that the output from a commercial power supply grid (14) is supplied to loads (16); a first supply path selector switch (9) capable of being closed such that the output from the power generation device is supplied to the loads without passing through the first current sensor; and a second supply path selector switch (10) capable of being closed such that the output from the power generation device is supplied to the loads via the first current sensor. The power supply system is further characterized in that the first current sensor is disposed between the interconnected-operation switch and the loads. |
