Summary: | The invention provides a virtual synchronous generator control method and device, and belongs to the technical field of virtual synchronous generator control. The method comprises the following steps: acquiring a frequency parameter of the distributed power generation system in real time; according to the current frequency parameter, detecting whether frequency disturbance occurs in the distributed power generation system; if frequency disturbance occurs in the distributed power generation system, rotational inertia and a damping coefficient corresponding to the current frequency parameter are determined, and adjustment coefficients in the rotational inertia and the damping coefficient are both proportionality coefficients; and based on the rotational inertia and the damping coefficient, using a preset adaptive control strategy to control a virtual synchronous generator in the distributed power generation system. The accuracy of rotational inertia adjustment can be improved, the adjustment time is shortened, |
