摘要
为科学发展新能源交通基础设施,对城市公共充电桩的建设选址优化展开研究.首先,考虑充电行为与停车行为的强关联性,提出静态充电需求的概念.其次,结合城市停车设施分布与安全间距要求,确定备选点位集合,并构建选址优化模型,在实现满足周边需求的同时,适应中心城区新能源汽车发展的总体规律,实现投建主体的收益最大化.再次,通过引入Voronoi图,平均划分备选点位之间服务范围的空间叠加,简化原模型的约束条件,并设计“两阶段”算法,降低原问题可行域维度,提升求解迭代效率.最后,以沈阳市三环内的城市核心区为实例进行分析.研究结果表明:基于静态充电需求的城市公共充电桩选址决策模型可通过优先在静态充电需求旺盛的区域布局城市公共充电桩,其在给定参数下,与传统的P-中心模型和集覆盖模型相比,充电收益可提升12.7%以上,充电服务覆盖范围更广,可以更好地保障新能源汽车发展,引导城市交通绿色化转型.
To promote the scientific development of new energy transportation infrastructures,this study focuses on the research of optimizing the site selection for urban public charging stations.Firstly,considering the strong correlation between charging and parking behavior,the concept of static charging demand is introduced.Subsequently,a set of alternative locations is determined by combining the distribution of urban parking facilities and safe distance requirements.An optimized model for site selection is then constructed to meet the surrounding charging needs,while adapting to the overall development trends of new energy vehicles in the central urban area,ultimately maximizing the benefits for investment entities.Moreover,the introduction of Voronoi diagrams is utilized to evenly divide the spatial coverage between alternative locations and simplify the constraints of the original model.A"two-stage"algorithm is designed to lower the feasible domain dimension and enhance solution iteration efficiency.Finally,the case study is conducted in the core area of Shenyang within the Third Ring Road.Results demonstrate that optimized location model for urban public charging stations,based on static charging demand,prioritizes the placement of public charging stations in areas with high static charging demand.This approach increased charging revenue by over 12.7%compared to traditional P-Center and Location Set Covering models under the given parameters.Furthermore,the broader coverage of charging services assists in fostering the development of new energy vehicles and guiding the greening of urban traffic.
