VSG
说明： 基于Matlab R-2018a版本搭建的虚拟同步发电机(VSG)三相离网变负载逆变器仿真，功率外环采用VSG控制，内环采用电容电压和电感电流双PI控制，仿真输出三相电压波形良好，输出频率跟踪也很理想。更详细的模块搭建步骤讲解可参考2018年华北电力大
学Sara Yahia Altahir Mohamed的博士学位论文《微电网并联运行虚拟同步发电机控制策略研究》P18页，Fig.2-8 Overall control of VSG.(Based on MATLAB r-2018a version of virtual synchronous generator (VSG) three-phase off grid variable load inverter simulation, the power outer loop adopts VSG control, the inner loop adopts double PI control of capacitor voltage and inductance current. The simulation output three-phase voltage waveform is good, and the output frequency tracking is also reasonable. For more detailed explanation of module construction steps, please refer to Sara Yahia altahir Mohamed's doctoral dissertation "Research on control strategy of virtual synchronous generator in parallel operation of microgrid" in 2018, page P18, fig.2-8 overall control of VSG.)
