摘要
电动汽车的发展普及使得城市交通系统和电网紧密耦合,二者的交互影响日渐显现。针对传统充电负荷分析未能有效考虑交通网络特性的不足,该文建立了基于交通均衡的充电负荷模拟方法。首先,考虑用户快速充电决策过程,提出快速充电负荷模拟框架。其次,建立混合车辆流交通均衡模型,考虑用户行为相互影响,对各充电站充电负荷进行计算分析。再次,建立最优路径生成模型并采用分支定价方法进行路径生成,求解交通均衡模型,提出快速充电负荷模拟的算法流程。最后以西安市交通路网为例验证模型正确性,说明在充电负荷分析中考虑交通因素的必要性。算例也揭示了利用电价调整充电负荷空间分布的可能性。
The development and popularization of electric vehicles(EVs)has made the urban transportation system and the power grid closely coupled.In most existing works,the traffic characteristics especially the interactions among vehicles are neglected in the charging load analysis.This paper proposed a charging load simulation method based on traffic equilibrium.Firstly,considering the decision process of fast charging,the framework of fast charging load simulation was proposed.Secondly,a traffic equilibrium model of mixed vehicle flow was established,and the charging load of each charging station was calculated and analyzed considering the interaction of user behavior.Thirdly,the optimal path generation model was established and the branch and price method was used to generate the path to solve the traffic equilibrium model.The case studied on Xi’an had verified the effectiveness and validity of the proposed method.The results had also shown the potential of electricity pricing in adjusting the spatial charging load.
