【摘要】：提出了在满足电动汽车充电需求的基础上尽量降低充电站充电成本的有序充电控制策略。分析了电动汽车充电所需时间与用户给定时间的关系,结合用户所需充电量,以充电站电费成本与电动汽车充电欠缺量惩罚费用之和最小为目标函数,以充电功率以及充电电量为约束,根据运营模式不同分别建立了充电过程中可更换充电机与不可更换充电机的数学模型。通过仿真模拟充电站2天内电动汽车的充电需求,基于混合整数规划和启发式快速算法求解数学模型,得到2天中充电站的充电决策矩阵和每辆电动汽车的充电欠缺量,验证了所提有序充电控制策略的可行性。仿真结果表明:与无序充电方案相比,有序充电控制策略可以更好地利用充电站的资源为用户服务,有效地降低了充电成本,并且有助于电网负荷的削峰填谷。
[Abstract]:An orderly charging control strategy is proposed to reduce charging cost of charging station on the basis of satisfying the charging demand of electric vehicle.This paper analyzes the relationship between the time required for electric vehicle charging and the time given by the user. Combined with the amount of charge required by the user, the sum of the charge cost of the charging station and the penalty cost of the charge shortage of the electric vehicle is taken as the objective function.Taking charge power and charge quantity as constraints, the mathematical models of replaceable charger and non-replaceable charger during charging process were established according to different operation modes.By simulating the charging demand of electric vehicles in charge station within 2 days, the mathematical model is solved based on mixed integer programming and heuristic fast algorithm, and the charging decision matrix of charging station and the charge shortage of each electric vehicle are obtained in 2 days.The feasibility of the proposed orderly charging control strategy is verified.The simulation results show that compared with the disordered charging scheme, the orderly charging control strategy can make better use of the charging station's resources to serve the users, reduce the charging cost effectively, and help to cut the peak and fill the valley of the power network load.
