1. A command generation device for generating a control command for an inverter configured to convert DC power output from a DC power source device into AC power synchronized with a frequency of a bus, the command generation device comprising:
a rotation target determination unit configured to determine, on the basis of active power of the bus at which the inverter is connected, a target value of the rotation speed of a virtual generator configured to monotonically decrease with respect to the active power;
a rotation calculation unit configured to calculate a rotation speed of the virtual generator on the basis of the determined target value of the rotation speed and a rotor model to simulate driving of the virtual generator and calculate the rotation speed of the virtual generator;
a target power determination unit configured to determine target values of active power and reactive power of the inverter on the basis of the calculated rotation speed; and
a command generation unit configured to generate a control command for the inverter on the basis of the determined target values of the active power and the reactive power.
