多并联模块化并网逆变器系统防止共模与交互不稳定性的通用设计程序

Based on the equivalent circuit model, the interactions of multi-parallel modular grid-tied inverters and their coupling effect with grid impedance are analyzed in this letter. The analysis shows that interactive instability could happen in the inverter system even when identical inverters have been used. However, if the control and circuit parameters are designed systematically, the system can be...
