Resilience-Oriented Load Restoration Considering the Topology Transition Process

With global climate change, the frequency of natural disasters increases. Network reconfiguration plays a critical pole in the load restoration. However, the topology transition process has not received much attention. Considering the transition process of network reconfiguration, this paper proposed a bi-level post-disaster distribution network restoration method to minimize the load lost and the voltage volatility. The transition process is modeled in this paper and the proposed method is formulated as a bi-level mixed integer linear programming model. A relaxation-based bi-level reformulation and decomposition algorithm is employed to achieve the optimal solution. The effectiveness of the proposed method is validated on the IEEE 33 node system.
