Research on Locating and Sizing of Electric Vehicles Charging Stations Based on Power-Charging Demand of Electric Vehicles

针对基于电动汽车充电需求的充电站选址定容问题,构建了计及电动汽车充电负荷的配电网经济性指标,并将电动汽车接入电网所带来的影响进行量化。从经济性方面,综合考虑了电动汽车入网方案投资成本、配电网网损增加成本与可靠性经济成本,以及所带来的售电效益与电动汽车环境经济效益,建立了考虑配电网经济成本-效益模型的电动汽车充电站选址定容模型,并对充电站的选址地点及容量配比进行了优化。以IEEE-33节点系统为例,对电动汽车接入电网充电的场景进行模拟,得到了充电站选址定容的优化方案。仿真结果验证了所提方法的有效性和可行性。

The problem of locating and sizing of electric vehicles charging stations based on power-charging demand of electric vehicles has recently received the increasing research attention.Distribution network economy and reliability indexes considering electric vehicles charging load are constructed to quantify the impact of electric vehicles charging brought to the grid.Considering the electric vehicles charging stations investment costs,distribution net loss costs,reliability economic costs,the sale of electricity benefits and environmental benefits in the aspect of economy,the charging stations locating and sizing planning is carried out.The model of locating and sizing of electric vehicle charging stations considering distribution network economic cost-benefit model is established.The location and capacity ratio of charging stations are optimized.As a case study,the IEEE33-bus system is simulated for simulating the scenarios of electric vehicles charging connected to the grid,which shows optimization schemes of the charging stations locating and sizing planning.The simulation have been obtained to test the effectiveness and feasibility of the proposed scheduling strategy.
