The interconnected operation of multiple microgrids can effectively deal with the power fluctuation caused by largescale distributed power supply access, and enhance the anti-interference ability of the system. A distributed autonomous coordinated control strategy is proposed for AC-DC hybrid multi-microgrid system. This strategy can reduce the dependence on communication system, realize power exchange among subgrids, and reduce the voltage or frequency offset of each subgrid effectively. Firstly, the reference voltage or frequency of each subgrid is established by the energy storage unit. Then, the bidirectional DC-DC converter (BDDC) or bidirectional AC-DC converter (BADC) of each subgrid adjusts the power output to ensure the reasonable power distribution of the system. Finally, the AC-DC hybrid multi-microgrid system simulation model was established in PSCAD/EMTDC, and different working conditions were simulated and verified. The simulation results show that the control strategy can realize the coordinated operation of multiple microgrids.
