Summary:In this paper, an approach for multi-grid coordinated resilience enhancement is proposed for optimal load recovery under extreme fault. In the active distribution network, different local and external flexible resources can be dispatched to enhance the resilience of the distribution grid. To guarantee the power supply, intentional islanding, time-series characteristic, and external microgrid connection is considered to minimize the network loss, load shedding, and scheduling cost by a mixed nonlinear programming (MINLP) model. In addition, to ease the burden of computation, the nonlinear model is reformulated into a mixed integer second-order cone programming (MISOCP) model by convex relaxation. To validate the advantages of the proposed method, case studies are conducted on a test IEEE 33-bus system connected with an external microgrid. Simulation results show that the proposed method can effectively improve resilience of the grid with optimal load recovery.
