The invention discloses a phase feedforward-based virtual synchronous generator control method. The control method comprises the following steps of 1) performing feedforward quantity calculation, subtracting power grid rated frequency from the output frequency of the virtual synchronous generator to obtain the frequency difference between the two parts, and multiplying the with a feedforward coincident k to obtain the compensation quantity ; 2) a droop control part, obtaining simulation mechanical power P of the virtual synchronous generator through calculation according to an output active power reference instruction P of the virtual synchronous generator and the frequency difference ; 3) performing simulation on a rotor mechanical equation, and obtaining output frequency according to the P and the actual output active power P; 4) performing integration on the output frequency and then adding with the phase feedforward control compensation quantity to obtain the output phase of the virtual synchronous generator; and 5) taking the phase obtained in the step 4) as a dp coordinate conversion phase, performing dp coordinate conversion on a dp coordinate voltage instruction value v<*>dp obtained by a reactive ring to obtain a three-phase voltage modulation signal v<*>abc in an abc coordinate, and enabling the modulation signal to be processed by a PWM modulator to obtain a control signal of a switch network for further driving the switchnetwork.
