English Abstract

With the rapid development of distributed renewable energy generation and integration, stability issues of power converters systems have been widely studied in recent years. Many previous studies focus on the transient stability of a single converter connected to the weak grid. However, the nonlinear dynamics and stability mechanism of multiple converters systems remain unclear. In this article, a...
