Aiming at the phenomenon of large-area power failure in the distribution network caused by extreme events,in the background of traffic-grid coupling,this paper proposes a post-disaster multi-source cooperative islanding operation strategy for the distribution network considering mobile energy storage system dispatching.First,based on the post-disaster operation framework in the background of traffic-grid coupling,with the objective of minimizing the weighted load shedding,and considering the influence of traffic flow changes on the dispatching process of mobile energy storage system,a multi-source cooperative islanding operation model is established.Then,according to the characteristics of the proposed model and the decision-making requirements,the decision-making process of islanding operation is established based on the two-stage optimization framework to ensure the coordination of load restoration between the island area after power loss and the area with local power supply.Finally,a case of IEEE 33-bus distribution network coupled with 29-bus traffic network is used to verify the effectiveness of the proposed strategy.The results show that the proposed islanding operation strategy can give full play to the collaborative ability of all power sources in the post-disaster distribution network restoration,achieve the optimal distribution and transfer of limited electricity,and effectively improve the post-disaster restoration effect of distribution network.
