  "textContent": "This command generation device generates a control command for a power conversion device which converts DC power outputted by a DC power supply device to AC power and supplies the same to a bus, and which converts AC power from the bus to DC power and supplies the same to the DC power supply device. Said command generation device comprises: a virtual power generation calculation unit which simulates the driving of a virtual power generator and, on the basis of a rotor model that calculates the rotational speed of the virtual power generator, calculates the root-mean-square voltage and phase of the virtual power generator; a bus calculation unit which calculates the voltage and phase at a point of contact between the power conversion device and the bus; a phase difference angle calculation unit which calculates the phase difference angle between the phase of the virtual power generator and the phase at the point of contact; a target power determination unit which determines a target value for the effective power of the power conversion device on the basis of the root-mean-square voltage of the virtual power generator, the voltage at the point of contact and the phase difference angle; and a command generation unit which generates a control command for the power conversion device on the basis of the determined target value for the effective power.",
