PROBLEM TO BE SOLVED: To provide a distributed power system that, when detecting an anomaly in an auxiliary power supply device, prevents a failure due to the anomaly.SOLUTION: A distributed power system having an auxiliary power supply device 10 having a power storage section 11, a power generation device 20, and a power consumption device 30 includes an anomaly determination device 40 for determining an anomalous state if detecting a high voltage state in which an internal voltage of a power conversion circuit section 13 of the auxiliary power supply device 10 is higher than a set upper limit voltage or detecting a reverse flow state in which power flows from an AC line 2 to the power conversion circuit section 13. A power supply control section 12 of the auxiliary power supply device 10 charges the power storage section 11 with power from the AC line 2 if the anomaly determination device 40 determines an anomalous state during such operational control of the power conversion circuit section 13 as outputs power from the power storage section 11 to the AC line 2 in a self-sustaining mode in which there is no power supply from a power system 1 to the AC line 2. |
