摘要：
The voltage and frequency deviation in steady state operation of distribution network will lead to low efficiency of inverter based on virtual synchronous generator(VSG). PID parameter configuration and self-tuning are the key factors to determine the performance of VSG control system. Based on the analysis of the traditional VSG control strategy, this paper proposes a VSG control strategy based on auto-coupling PID. By calculating the mathematical model of the VSG, The parameters of the controller are adjusted in real time by using the auto-decoupled PID algorithm. The voltage and frequency inertia effects of the VSG were verified by MATLAB/Simulink modeling and simulation. Simulation results show that the VSG based on self-coupling PID has better performance of regulating voltage and frequency, and can meet the requirements of normal operation of distribution network.
