Optimal Resilience Enhancement Strategy for Power Distribution System with Line Reinforcement and Emergency Generator Placement

In recent years, an growing number of extreme weather events have led to large-scale outages. Therefore, the enhancement of power distribution system (PDS) resilience has become more and more important. This paper proposes an optimal resilience enhancement strategy for PDS with line reinforcement and emergency generator (EG) placement during an extreme weather event. Firstly, taking typhoon as an example, the failure probability of distribution lines are obtained based on the extreme weather event model. Then the Monte Carlo method (MCM) is applied to acquire the fault sets of distribution lines. After that, the optimal planning strategy of line reinforcement and EG placement based on multiple fault sets is obtained by the PDS resilience enhancement model. Finally, we verify the effectiveness of the method with a modified IEEE 33-bus distribution test system. This results can provide a reference for utilities to develop a resilience enhancement strategy under a given budget.
