Abstract:  In order to reduce the impact of natural disasters and other human factors on power system， a post-disaster recovery strategy of resilient distribution network considering the interactive optimization of mobile energy storage system and network reconfiguration is proposed in this paper. Considering the maximization of load recovery， this strategy firstly estimates the network after the disaster， analyzes the number of micro-grid formation， and carries out network reconstruction. Secondly， according to network reconstruction results， the access location of mobile energy storage system is optimized， and the removal of mobile energy storage follows the principle of the shortest time. Finally， a new network reconfiguration of the distribution network is carried out to meet the requirements. The strategy proposed in this paper can minimize the load loss and maximize the use of renewable energy on the basis of security operation of isolated islands. It reduces the impact of disasters on power system and greatly increases the resilience and economy of the distribution network. Finally， this paper takes IEEE 33-node system as an example to simulate disaster recovery in different scenarios， and verifies the effectiveness and practicability of the proposed strategy.
