摘要(Abstract)：

电池储能系统(batteryenergystoragesystem,BESS)在电力系统中应用愈加广泛。BESS在实际运行工况中存在差异性,导致电池组寿命衰减速度不一。为了延缓电池组寿命衰减、提高BESS使用年限,提出一种考虑电池组健康状态的BESS能量管理方法,该方法首先根据调度指令功率大小确定电池组充/放电个数,然后将电池健康状态融入到电池组充放电优先级排序规则中,最后运用数学规划算法求解功率在各电池组间的分配。以青海某光储电站BESS历史运行曲线为算例,对比试验表明,所提出的变参考值能量管理方法能够以"新电池深充深放,旧电池浅充浅放"为原则,自适应调整各电池组间的功率分配,达到延长电池组使用寿命的目的。
