Abstract：In recent years, with the development of microgrids, multi-microgrids (MMGs) have become a new type of power grids. As the community of microgrids with more complex structure and control mode, studies on safe and effective black start strategies for multi-microgrids are of great significance to improve the reliability of power supply. Based on the analysis of the network structure and the control system of the multi-microgrids with three-phase/single-phase architecture, to achieve the efficient operation of the main power supply, a black start strategy is proposed under the con-sideration of three-phase unbalance degree constraints. The energy storage system that meets the sources-loads-network conditions is selected as the main power supply of the MMGs, and after all sub-micogrids finish independent decentralized restoration, the centralized restoration is carried out to complete the MMGs black start procedure. The proposed method is demonstrated to be effective and reliable, which can provide some reference for the restoration of the multi-microgrids.
