从电动汽车用户、电力公司、充电站运营商、道路交通部门四个方面展开电动汽车最优充电导航策略的研究,提出“车—网—路—站”多目标优化有序充电导航系统。在此基础上,采用模糊决策法建立综合最优目标模型,实现了在大规模电动汽车快速充电需求下,电动汽车用户利益最优、电力公司网络损耗与电压偏移最小、负荷平衡指数最高、充电站运营商利润最高及交通网侧道路拥堵率最低等多维目标。通过某市交通路网中呈均匀分布的9个充电站及IEEE 14节点系统算例,验证了该智能充电服务策略的合理性及有效性。
From the four aspects of electric vehicle users, power companies, charging station operators and road traffic departments, the paper studies the optimal charging navigation strategy for electric vehicles, and proposes a multi-objective optimized sequential charging navigation system . On this basis, the fuzzy optimal decision-making method is used to establish a comprehensive optimal target model, which achieves the best interests of electric vehicle users under the requirement of large-scale rapid charging of electric vehicles, minimizes the network loss and voltage deviation of power companies, and has the highest load balancing index, Charging station operators the highest profits and the traffic network side road congestion rate and other multidimensional goals. Through an example of 9 charging stations and IEEE 14-bus system which are uniformly distributed in the traffic network of a certain city, the rationality and effectiveness of this intelligent charging service strategy are verified.
