The invention proposes a distributed photovoltaic power generation system control strategy based on a virtual synchronous generator, belongs to the technical field of distribution photovoltaic power generation control, and particularly relates to the distributed photovoltaic power generation system control strategy based on the virtual synchronous generator. The invention provides the distributed photovoltaic power generation system control strategy based on the virtual synchronous generator, which can be used for effectively preventing power fluctuation of the system during the dynamic transition process. The distributed photovoltaic power generation system control strategy comprises a photovoltaic array, a power electronic convertor circuit, a power frequency controller, an excitation controller, a virtual synchronous power generator body control link with feed-forward compensation and a sinusoidal pulse width modulation (SPWM) trigger pulse generation device, wherein the structural key lies in that an output end of the photovoltaic array is connected with an input end of the power electronic convertor circuit, and an output end of the power electronic circuit is connected with an AC bus, a signal input end of the power frequency controller, a signal input end of the excitation controller and a signal input end of the virtual synchronous power generator body control link with the feed-forward compensation.
