Electric Buses-Based Resilient Distribution Network Multi-Period Power Supply Restoration Strategy

When disasters leading to electricity shortages, electric buses can interact with the power system through bus-to-grid technology, serving as post-disaster emergency resources. Therefore, this paper designs a resilient distribution network multi-period power supply restoration strategy based on electric buses, which can improve the speed of post-disaster power supply restoration. Firstly, based on the coupling of the power grid and the transportation network, travel chains are used to characterize the operation of electric buses before the disaster, providing data for post-disaster recovery; secondly, typhoon scenario is generated based on the fault probability of lines and towers; then, the scheduling of electric buses is optimized using a time-space network to derive a multi-period power supply restoration strategy for electric buses; finally, a 33-node distribution network case study is designed to verify the effectiveness of the proposed method.
