摘要
随着电动汽车的逐渐普及,电动汽车充电桩的大规模接入会对电网的运行规划产生重大影响。提出了一种以预约为前提条件,面向用户端的电动汽车智能充电控制策略。根据充电桩实时运行状态,结合对电动汽车充电时间的预测,并充分考虑用户需求,建立了电网控制端-计算机处理终端-智能充电桩终端-电动汽车用户端之间的信息反馈系统数学模型。通过算例分析,结果表明:采用所提出的充电控制策略,可显著提高充电系统运营效率,适用于大规模电动汽车智能充电系统。
With the increasing popularity of electric vehicles,the large-scale access of charging piles for electric vehicles will have a significant impact on the operation planning of the power grid.An intelligent charging control strategy for electric vehicles was proposed based on the reservation.According to the real-time running state of the charging pile,combined with the prediction of the charging time for electric vehicles,and fully considering the users′demand,the mathematical model of the information feedback system among the control terminal of the power grid-the terminal of the computer processing terminal-the terminal of the intelligent charging pile-the user terminal of the electric vehicle was established.The results of the calculation example analysis show that the proposed charging control strategy can significantly improve the operating efficiency of the charging system,and it is suitable for the intelligent charging system of large scale electric vehicles.
