The invention relates to a virtual inertia power compensator control method and system applied to an electric vehicle charging station and a medium. In order to solve the problems of lack of system inertia and failure in complete development and utilization of the load storage capacity of an electric vehicle caused by wide access of the electric vehicle charging station at present and capacity increase of a power electronic device in the system, the invention creatively constructs an evaluation method for the dynamic regulation capacity of the electric vehicle charging station. The electric vehicle charging station is proved to have the generalized energy storage characteristic and have the power system inertia supporting capacity. A rotor power equation is decoupled according to a VSG algorithm, a virtual inertia power compensation control strategy is designed to be applied to charging station level inverter control, inertia support is introduced at a load access point, the excellent load storage capacity of the electric vehicle is fully played, the inertia in the system is improved, and the load disturbance resistance of the system is improved.
