摘要
针对VSG控制原理无法为独立型微电网提供必要的惯量支撑以及阻尼作用的问题,通过建立VSG控制的小信号,分析VSG控制中2个重要参数J和D对系统稳定性的影响以及作用机理,确定了2个参数的选取原则,最后通过MATLAB/Simulink仿真验证其正确性。
VSG control principle cannot provide necessary inertia support and damping for independent microgrids.In view of this the present study establishes the small signal of VSG control,analyzes impact and mechanism of two important parameters J and D in VSG control on system stability,and determines selection principles of the two parameters.The correctness of the proposed scheme is verified through MATLAB/Simulink simulation.
