基于双序动态耦合模型的不对称电网故障下跟网型逆变器同步稳定性分析

To deal with asymmetrical grid faults, grid-following inverters are required to output positive- and negative-sequence currents to regulate the voltage at the point of common coupling. Owing to the negative-sequence current injection, the stability mechanism of the dual-sequence synchronizations becomes more complicated under asymmetrical scenarios. In this article, a dual-sequence dynamic couplin...
