description The invention discloses a network source coordination virtual synchronous machine control method of an optical storage integrated system. An optical storage integrated system based on the method is ofa two-stage structure. Photovoltaic and energy storage are connected to a power grid by adopting the same inverter, photovoltaic and energy storage batteries are respectively connected to a direct current bus of the inverter in parallel through respective DC/DC converters, and the two DC/DC converters and the inverter are controlled by adopting a network source coordination virtual synchronous machine control scheme. The inverter realizes inertia control and reactive droop control; a DC/DC converter of the battery realizes active droop control; when the voltage of the direct-current capacitoris not higher than the upper limit value Udcuplimit, the photovoltaic DC/DC converter realizes maximum power output control; and when the voltage of the direct current capacitor exceeds the upper limit value Udcuplimit, the p
