(57) Abstract: This power generation system is provided with: a plurality of power conversion devices for converting DC 
power from a DC power supply to AC power; and a plant control device for controlling the plurality of power conversion 
Devices. The plant control device includes a virtual synchronous generator model unit for outputting power command 
values on the basis of the current and voltage values at a system interconnection point on the output side of the plurality 
of power conversion devices. The plurality of power conversion devices output AC powers according to the power com-
