Abstract: The comprehensive promotion of electric vehicles is critical for green and low-carbon energy transformation and dual-carbon goals in China. Battery swapping station is a hub to meet the battery-swapping demands of EVs and consumes renewable energy power (REP). Moreover, the potential of battery swapping station cluster (BSSC) must be explored urgently. Therefore, the day-ahead dispatching model of BSSC is proposed for the efficient consumption of REP and battery-swapping demands of electric taxis (ETs) in this paper. Firstly, the battery-swapping demands of ETs in dynamic spatiotemporal distribution are aggregated by the KNN algorithm. Secondly, a dual-objective model of the day-ahead dispatching model with economy and efficient consumption of REP is constructed, and the NSGA-II algorithm obtains the optimal strategy. Finally, taking a city of China as an example, the charging-discharging strategy of BSSC is provided. The results show that the day-ahead dispatching model is of practical significance to get an optimal charging-discharging strategy of cluster loads for REP consumption and economic battery-swapping service.
