Optimal Planning of AC Charging Piles Based on Constraints of Time and Space

针对电动汽车充电需求增加,通过分析电动汽车充电量总体需求、多场景运行模式及商业运营模式等因素的影响,建立以交流充电桩建设和管理费用、电动汽车路上运行费用及充电等待费用最小为目标函数的交流充电桩建设模式,并给出该模式的仿真求解过程。通过算例求解验证了该交流充电桩建设模式的可行性,可根据区域内电动汽车数量预先计算交流充电桩的建设数量及位置。该研究可有效降低交流充电桩的建设费用,快速、健康、高效地推动电动汽车产业的发展。

In view of the increasing charging demand of electric vehicles, a construction pattern of AC charging piles is established through analyzing the influencing factors, such as the overall demand on electric vehicle charging quantity, multiscenario operation mode and the commercial operation mode. The objective function of the construction pattern is to minimize the fees of charging piles construction and management, the running fees of the on the-road electric vehicles and the waiting fees. The simulation solving process of the model is also given. The feasibility of the AC charging piles construction pattern is validated by example, and the number and location of the charging piles can be pre-computed in one area according to the quantity of regional electric vehicles. The study can effectively reduce the construction costs of AC charging piles while promoting the development of the electric vehicle industry faster, and more healthily and effectively.
