摘　　要：随着光伏发电大量并网,电力系统调频问题日益突出,传统基于最大功率追踪控制的光伏并网策略不能响应电力系统的频率变化,因九,开展光伏发电主动参与电网频率调节的研究具有现实意义。本文设计了因负荷功率投切产生的电网频率波动场景,并基于Matlab/Simulink仿真平台构建了外界环境变化下的光伏发电虚拟同步机并网模型,通过算例分析验证了本文模型能够满足高光伏渗透率下的电网调频需求。With a large number of photovoltaic power generation connected to the grid,the frequency modulation problem of power system becomes increasingly prominent,and the traditional photovoltaic grid-connected strategy based on maximum power tracking control cannot respond to the frequency change of power system.Therefore,it is of practical significance to carry out the research on photovoltaic power generation actively participating in the frequency regulation of power grid.In this paper,the grid frequency fluctuation scene caused by load power switching is designed,and the grid—connected model of photovoltaic virtual synchronous machine under the changing external environment is built based on Madab/Simulink simulation platform.The example analysis proves that the model can meet the demand of grid frequency modulation under high photovoltaic permeability.
