Zusammenfassung:A processing unit of a command generation device which is provided separately from a general-purpose inverter, performs following processing. A rotation calculation unit calculates a value relating to a rotation of a rotor of a virtual power generator when the virtual power generator is driven according to an active power command based on a rotor model that simulates a driving of the virtual power generator and calculates a value relating to the rotation of the rotor of the virtual power generator and an active power command. A target determination unit determines a target value of a voltage frequency and a target value of an active power based on the calculated value relating to the rotation. A command generation unit generates a control command for the inverter based on the determined target value of the voltage frequency and the target value of the active power. A time constant relating to a synchronization power of the rotor model matches a time constant relating to a synchronization power of the AC power generator.
