基于电感模拟的不平衡电网下三相并网VSC频率耦合抑制控制

For three-phase grid-tied voltage-source converters (VSCs), the presence of unbalanced grids (unbalanced grid voltages, asymmetric line impedances, etc.) tends to excite the frequency coupling effect (FCE), posing a challenge to system modeling and stability analysis. In this article, a frequency coupling suppression control strategy is developed for three-phase grid-tied VSCs to deal with FCEs ca...
