Photovoltaic virtual synchronous machine stability control method of self-adaptive inertia coefficient

The invention discloses a photovoltaic virtual synchronous machine stability control method of an adaptive inertia coefficient. A system comprises a photovoltaic power generation system, an energy storage device, an inversion device and an adaptive inertia coefficient virtual synchronous machine device with DC end additional control. A closed-loop pole returns to the left side of a virtual axis, stable operation of a system is guaranteed, and meanwhile the output power pulsation phenomenon can be reduced. 一种自适应惯性系数的光伏虚拟同步机稳定控制方法，该系统包括光伏发电系统、储能装置、逆变装置和带直流端附加控制的自适应惯性系数虚拟同步机装置；其令闭环极点回到虚轴左边，保证系统的稳定运行，同时可减少输出功率脉动现象。
