Lixue Zheng, Chuan He, Yixiang Lin, Yitong Ning · 2024
As a common extreme natural disaster, typhoon has a great impact on the normal operation of distribution network. Pre-disaster reinforcement of the distribution network can effectively reduce the losses caused by extreme weather events. In this paper, a pre-disaster reinforcement method for distribution network system considering minimum load loss and economic constraints is proposed. By establishing a model that comprehensively considers demand response and energy storage equipment, a multi-level resilience improvement strategy is proposed. The strategy is applied to the improved IEEE33 node distribution system. The results show that the proposed method can effectively improve the resilience of the distribution network system and ensure its safe operation in extreme weather.
