摘　　要：为解决传统虚拟同步发电机(VSG:Virtual Synchronous Generator)电压电流双闭环控制的抗扰动性能差,受系统参数变化及各种不确定影响较大等问题,在建立微电网VSG转动惯量自适应控制模型的基础上,采用一种基于跟踪微分器的非线性PID(Proportion Integration Differentiation)实现电压外环和电流内环的控制,并根据输出信号的反馈值实时调节系统动态响应,从而达到稳定输出的效果。通过仿真验证了基于非线性PID的微电网虚拟同步发电机双闭环控制的正确性和有效性。In traditional VSG(Virtual Synchronous Generator) voltage and current double closed-loop control,the anti-disturbance performance is poor,and the influence of system parameter changes and uncertainties is great.In order to solve the problems,a nonlinear PID(Proportion Integration Differentiation) based on tracking differentiator is used to control the outer voltage loop and the inner current loop,and the dynamic response of the system is adjusted in real time according to the feedback value of the output signal,so as to achieve the effect of stable output.The correctness and effectiveness of the double closed-loop control of microgrid virtual synchronous generator based on nonlinear PID are verified by simulation.
