基于VSC的直流微电网分布式交直流耦合分层控制

In this article, a distributed ac–dc coupled strategy for the hierarchical control of voltage source converter (VSC)–based dc microgrids is proposed. Unlike existing hierarchical control methods, this approach directly controls the ac inductor current (id) of the VSC's inner loop in both primary and secondary layers to achieve proportional power sharing and voltage regulation. Specifically, an ac ...
