報告內(nèi)容： Currently, several secondary control strategies including centralized, decentralized and distributed control have been proposed to solve the secondary voltage restoration and power sharing problem in DC microgrids. However, each strategy has its own merits and demerits. How to enjoy their merits and avoid their demerits is an interesting but challenging problem. In this talk, a first attempt on designing a decentralized cluster-based distributed secondary control strategy is made towards the goal of accurate voltage restoration and power sharing. Specifically, we divide all the distributed generators (DGs) into several clusters. Then, for DGs within the same cluster, a distributed finite-time control approach is proposed; while no information exchange is involved among different clusters. Thus, all the distributed controls of different clusters are totally decentralized. If each cluster has only one DG, our proposed control strategy reduces to the existing decentralized approaches, while the case of one cluster boils down to distributed control. Rigorous theoretical analysis for such control strategy is given. Compared to existing methods, our proposed strategy has better transient and steady-state performance than purely decentralized one and better robustness than distributed one. The proposed method is validated in an experimental test system built in OPAL-RT.
