摘要
Virtual synchronous generator (VSG) is a hotspot in the control strategy research of grid-connected inverters in recent years, but the research on the parameter design of VSG reactive power-voltage loop is rare. Firstly, taking robust VSG as an example, small signal model between reference voltage, and the output of reactive power and reactive voltage is established. Then the decoupling between reactive power-voltage loop and active power loop is realized through gain comparison analysis, and a second-order mathematical model of the output of reactive power-voltage of VSG is obtained. Referring to design requirements of excitation system parameters of synchronous generator recommended by IEEE and IEC, the parameters of VSG reactive power-voltage loop are designed. Finally, simulation and experiment results verify the effectiveness of the proposed method. © 2019 Automation of Electric Power Systems Press.
