摘要(Abstract):
在分析电动汽车动力电池特性的基础上提出了电动汽车分布式储能的概念。在满足电池约束、电网约束和车主约束的基础上提出了电动汽车分布式储能的控制策略。电动汽车分布式储能控制中心根据实时电动汽车并网(vehicleto-grid,V2G)参与情况以及电动汽车自身充放电标志,将所有电动汽车分为EVs1和EVs2两个车群:EVs1负责充电,EVs2负责放电。车群管理系统根据每辆电动汽车上一时刻充放电状态以及电网对分布式储能的功率要求,动态管理每个车群。每辆电动汽车实现了与分布式储能控制中心的信息双向交换,和与电网的能量双相交换。通过提高分布式可再生能源可调度性的算例仿真,验证了所提电动汽车分布式储能控制策略显著提高可再生能源可调度性的同时,大幅降低了电动汽车充放电切换次数,从而减缓了电动汽车动力电池寿命的衰减。
