Post-disaster distribution network resilience improvement strategy based on optimal configuration of mobile energy storage

Distribution network is an important bridge to ensure the power consumption of power users. Therefore, the resilience of distribution network should be improved for small probability and large impact events caused by extreme disasters. This paper presents a resilience improvement strategy of distribution network based on movable energy storage equipment (MESS) configuration. Firstly, the distribution network resilience identification index is proposed to measure the resilience improvement effect of this method. Secondly, considering the importance of distribution networks in different regions, different configuration weights are established, and MESS is introduced to support the operation power of post disaster distribution network. Aiming at minimizing the cost of post disaster MESS configuration, operation and load shedding, and considering the constraints of distribution network operation and mess operation, a single-layer model of post disaster optimal dispatching operation of distribution network is formed. Finally, the IEEE-33 node standard test system is used for example analysis to verify the applicability of the proposed optimization strategy.
