A Cooperative Post-disaster Repair and Restoration Strategy for Distribution Networks Considering Spatiotemporal Uncertainty of Electric Vehicles
In response to large-scale power outages in distribution networks caused by extreme disasters, as well as the low efficiency and limited resources of traditional repair methods, a cooperative post-disaster repair and restoration strategy considering the spatiotemporal uncertainty of electric vehicles (EVs) is proposed to guide randomly distributed EVs to actively participate in the restoration process. First, the disaster-affected area is partitioned based on Voronoi Diagram (VD) principles, and a generative adversarial network (GAN) is used to generate the initial location sets of EVs to characterize their stochastic distribution after disasters. Second, a power supply incentive mechanism integrating charging contribution and economic benefits is designed to enhance EV owners' willingness to participate. Subsequently, repair crews and EV resources are coordinated to establish an optimization model aimed at minimizing the comprehensive post-disaster repair and restoration cost of the distribution network, thereby achieving optimal fault repair and power recovery. Finally, a simulation validation is conducted using Xinyi City, Guangdong Province, affected by Typhoon Saola in 2023 as an example. The results demonstrate that the proposed strategy can effectively shorten repair time and improve restoration efficiency.
