考虑充-换电站电池能量转供链路的配电网灾前-灾后两阶段恢复策略OA北大核心CSTPCD

A two-stage,recovery strategy for distribution networks pre-and post-disasters is proposed to address the issue of transmission-line failures caused by extreme events(such as extremely cold weather and typhoons)which result in a significant loss of power in the distribution network,considering the coordination of battery-charging switching stations(BCSS)for electric vehicles.We analyzed the feasibility of the BCSS participation in the pre-to post-disaster distribution-network restoration and two-stage,restoration architecture and constructed a refined energy-transfer link model for BCSS;a thermal-management system was constructed considering the impact of a low-temperature environment.We proposed a two-stage,recovery strategy for a distribution network that considers the BCSS before and after a disaster.In the pre-disaster stage,the allocation of battery packs was decided.In the post-disaster stage,based on the remaining resource power-supply potential—the objective function was the maximization of the overall economic optimization to ensure a stable load operation.Finally,numerical simulations were conducted using the improved IEEE33 node and 123 node-distribution networks as examples.The results indicated that the proposed strategy is both feasible and superior and could improve the recovery rate of important loads in the distribution network while ensuring lower recovery costs.
