Abstract: Global increase in large-scale outages caused by small-probability and high-impact extreme events has attracted extensive academic attention to the disaster response capability of multi-microgrid systems. In order to improve the ability of multi-microgrid systems to cope with extreme events, this paper proposes a two-stage energy management and scheduling method based on the system of systems（SoS） architecture. By making full use of various power generation resources in the systems, the power supply capacity of multi-microgrid systems can be maximized when it is disconnected from the main grid. Meanwhile, this paper also proposes a resilience index system to evaluate the ability of multi-microgrid systems to cope with the extreme events. The effectiveness of the proposed method is verified by comparing with the traditional multi-microgrid energy management method.
