Abstract：This study proposes a planning model for optimizing load supply and demand using electric vehicle charging and discharging.Considering the convergence of commercial district load and pedestrian flow,based on the functions and pedestrian flow scale of different areas,the Imperial Competition Algorithm is used for preliminary planning of pile positions.By implementing charging and discharging discount strategies,statistics and optimization of pile utilization efficiency are conducted to improve overall efficiency.In response to the potential changes in load and pedestrian flow caused by the development of commercial areas,this study has made reversible improvements to the algorithm and planned and simulated based on one week's real load data of a certain commercial area.The results show that under the improved model,the participation of electric vehicles in charging and discharging can reduce the peak load of the commercial area by 39%and the peak valley difference by 43.2%,effectively promoting the balance of load supply and demand,and bringing significant economic benefits to the commercial area.
