PROBLEM TO BE SOLVED: To provide a distributed power supply system operating a plurality of distributed power supplies submissively to a voltage phase and a current of a power system at a normal time, and being switched to a cooperative autonomous operation during an interruption of power supply service, and to provide an autonomous operation control device for distributed power supplies.SOLUTION: A distributed power supply system 100 is installed to a private main circuit 2 connected with a power system 1 via a power distribution board 10. This distributed power supply system 100 comprises a plurality of distributed power supplies 3, an interconnected circuit breaker 16, and an operation switching part 550. Each distributed power supply 3 comprises: an inverter device that can switch between current control and voltage control; and a power generator 300 such as a photovoltaic power generator and a secondary battery. The interconnected circuit breaker 16 is provided to the power distribution board 10, and separates the power system 1 and the private main circuit 2 from each other when a voltage at the power system 1 side becomes a constant value or less. In addition, the operation switching part 550 switches a part of the plurality of inverter devices to the voltage control at a timing of separation by the circuit breaker. |
