- Abstract
A hybrid series‐parallel microgrid structure and its distributed decentralized cooperative control strategy are introduced in this paper. In the hybrid series‐parallel microgrids, the distributed generators (DGs) are concatenated in parallel to form a paralleled‐connected generation (PCG) module. Further, the hybrid series‐parallel microgrids consist of multiple PCG modules in series. For the considered microgrids, a distributed decentralized cooperative control strategy is proposed. For DGs in the same PCG module, low‐bandwidth communications are applied to obtain convergence control of the system. Meanwhile, different PCG modules realize autonomous synchronization in a communication‐free manner. Thus, the proposed distributed decentralized cooperative control method is a low‐bandwidth communication approach. Moreover, it is immune to single‐point fault and communication failure. Finally, the feasibility of the proposed controller for the considered microgrids is verified by stability and simulations.
