A Hybrid Series-Parallel Microgrid and its Low-dependent Communication Control

This paper proposes a new hybrid series-parallel microgrid and its low-dependent communication control scheme. The separate distributed generators (DGs) are paralleled connected as a paralleled-connected generation (PCG) module. These PCG modules are series connected to form a hybrid series-parallel microgid. Then, a low-dependent communication control scheme is proposed, in which only the local low-bandwidth communication network is needed to realize the consensus control for the PCG modules. Further, these PCG modules are synchronized autonomously without any communications. Thus, the low-dependent communication features are obtained. Finally, the feasibility and performance are verified by simulations.
