Abstract
With the increasing severity of global energy crises and environmental pollution, electric vehicles (EVs), as a crucial component of green transportation, are becoming increasingly prevalent. Consequently, power allocation and optimal scheduling at EV charging stations have emerged as critical issues requiring immediate attention. This study addresses the inherent conflict between efficiency and fairness in power distribution at EV charging stations by proposing a dynamic scheduling algorithm based on multi-ob jective optimization. By incorporating a priority weighting mechanism and real-time load balancing strategies, the algorithm effectively reduces charging waiting times while enhancing grid utilization. A mixed-integer linear programming model is employed to formulate the power allocation problem at charging stations, and an efficient solution approach is designed by leveraging the strengths of genetic algorithms and particle swarm optimization. Experimental results demonstrate that the proposed algorithm exhibits superior performance under various operating conditions, reducing average charging waiting times by approximately 35% and peak grid loads by about 20% compared to conventional methods. Additionally, the algorithm demonstrates strong robustness and scalability, making it applicable to charging stations of varying sizes. The primary contribution of this research lies in the development of an optimization scheduling fr amework that balances efficiency and fairness, providing theoretical support and technical references for the intelligent management of EV charging infrastructure.
