台风场景下基于多种分布式资源协同的弹性配电网两阶段供电恢复策略

In recent years, frequent natural disasters have greatly threatened the safe operation of distribution network. Considering the characteristics of different distributed resources and giving full play to the complementary advantages of distributed resources are helpful to solve the problems of partial line damage and insufficient power supply in post-disaster distribution network and to realize the rapid recovery of power grid after disaster. Under the background of the continuous enrichment of distributed resources in the power grid, this paper proposes a two-stage power supply recovery strategy for resilient distribution network based on the coordination of multiple distributed resources before and after the disaster of typhoon. Firstly, the influence of the coupling of distribution network and transportation network is taken into consideration, and the location model of mobile energy storage system and repair crew emergency warehouse is established with the goal of minimizing the weighted loss of power expectation while considering the scheduling of electric vehicles in the pre-disaster stage. Secondly, according to the post-disaster response characteristics of the above three distributed resources and flexible loads, the post-disaster stage is divided into two processes, namely, emergency power support and rapid load recovery, and a multi-period post-disaster recovery optimization model of distribution network is built. Then, through in-depth study of the advantages and disadvantages of various distributed resources, a two-stage power supply recovery framework for distribution network is designed. Finally, several sets of cases are designed to verify the effectiveness and feasibility of the proposed method.
