    摘要:

    随着电动汽车快速增长,充电站数量不足、分布不均及可靠性问题日益突出,成为影响使用和运营效率的关键因素。考虑到充电站选址过程中面临的潜在中断风险,本文构建了电动汽车充电站可靠性选址多目标优化模型,旨在通过最小化系统总成本、最大化用户时间满意度及平均充电站可达率,实现经济性、高效性和可达性的协同优化。利用NSGA-III求解模型,获得系统成本、用户满意度和可达率之间的Pareto最优解集。基于成都市三环内路网及POI数据开展实验,验证所提模型在实际场景中的应用潜力。通过超体积、反世代距离、均匀性与多样性指标评估算法性能,并与NSGA-II对比。同时,对中断概率和紧急情况占比进行灵敏度分析,探讨模型的稳定性与适应性。研究结果表明,所提模型和方法可有效应对充电站选址中的中断风险,增强充电网络韧性,为充电站可靠性选址提供参考。

    Abstract:

    With the rapid growth of electric vehicles, insufficient charging stations, uneven distribution, and reliability issues have become key factors affecting usage experience and operational efficiency. Considering potential disruption risks during the charging station location process, this paper develops a multi-objective optimization model for reliable electric vehicle charging station location. The model aims to achieve coordinated optimization of economy, efficiency, and accessibility by minimizing the total system cost, maximizing user temporal satisfaction, and improving the average station accessibility. NSGA-III is adopted to solve the model, yielding a Pareto-optimal solution set that reflects the trade-offs among system cost, user satisfaction, and accessibility. Experiments are conducted based on the road network and POI data within the Third Ring Road of Chengdu to validate the model’s applicability in real-world scenarios. The algorithm’s performance is evaluated using hypervolume, inverted generational distance, uniformity, and diversity metrics, and compared with that of NSGA-II. Additionally, a sensitivity analysis is performed on the disruption probability and the proportion of emergency to explore the model’s stability and adaptability. The results indicate that the proposed model and method effectively address disruption risks in charging station location, enhance the resilience of the charging network, and provide a scientific reference for reliable charging station location optimization.
