1. A distributed power supply management device that manages a plurality of distributed power supplies connected to a distribution system, each of the plurality of distributed power supplies including a static inverter in which virtual synchronous generator control is implemented, the distributed power supply management device comprising:
a communication circuit to communicate with the plurality of distributed power supplies;
an operation plan creation circuit to create a power target value of each of the plurality of distributed power supplies on a basis of information received by the communication circuit and capacities of the plurality of distributed power supplies; and
a control parameter generation circuit to generate a control parameter for the virtual synchronous generator control in each of the distributed power supplies or information necessary for generating the control parameter, wherein
the communication circuit is configured to receive measurement information of each of the distributed power supplies, and to transmit a control command to each of the distributed power supplies, and
the control parameter generation circuit
generates the control parameter or the information necessary for generating the control parameter on a basis of the information received by the communication circuit, the capacities of the plurality of distributed power supplies, and the power target value of each of the distributed power supplies, and
outputs the control parameter generated or the information necessary for generating the control parameter as the control command to each of the distributed power supplies via the communication circuit.
