PROBLEM TO BE SOLVED: To provide a distributed power supply system capable of continuously supplying power to a load even when abnormality occurs in system voltage of a power system.SOLUTION: Direct current generated by a photovoltaic power generation facility is converted to direct current of predetermined output voltage by a DC/DC converter 11. The direct current converted by the DC/DC converter 11 is converted to alternating current by an inverter 12, and is output to a power system 15 through a system linkage switch 14. When system voltage of the power system 15 is abnormal, a control device 20 opens the system linkage switch 14, switches an operation mode of the DC/DC converter 11 and the inverter 12 to migrate to an autonomous mode without stopping the DC/DC converter 11 and the inverter 12, and supplies power to a load 17 connected between the inverter 12 and the system linkage switch 14. |
