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.

    本发明涉及一种应用于电动汽车充电站的虚拟惯性功率补偿器控制方法、系统及介质。针对目前电动汽车充电站广泛接入,系统中电力电子装置容量增加,导致系统惯性缺乏以及电动汽车储荷能力未能完全开发利用的问题,本发明创造性地构建电动汽车充电站动态调节能力评估方法,印证电动汽车充电站具备广义储能特性,具备电力系统惯性支撑能力。根据VSG算法解耦出转子功率方程,设计虚拟惯性功率补偿控制策略,以应用于充电站层面逆变器控制中,在负荷接入点引入惯量支撑,充分发挥电动汽车优秀的储荷能力,提高系统中的惯性,提升系统的抗负荷扰动能力。
