摘要
基于MATLAB/Simulink仿真软件,搭建光储并网系统详细模型,对储能系统分别采用U-Q控制策略和虚拟同步(Virtual Synchronous Generator,VSG)控制策略进行仿真,针对光伏功率突变以及电网电压跌落情况,对比两种控制策略的仿真效果,验证虚拟同步发电技术对电网的友好性。
Based on MATLAB/Simulink simulation software,a detail model of PV and energy storage grid-connected system was built.The U-Q control strategy and virtual synchronization generator(VSG)control strategy are used to simulate the energy storage system.In view of the sudden change of photovoltaic power and voltage drop of power grid,the simulation results of the two control strategies are compared to verify the friendliness of virtual synchronous generation technology to power grid.
