A distributed decentralized cooperative control scheme for microgrids

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