摘要(Abstract)：

为提高独立光伏系统的供电可靠性和光伏利用率,需要合理配置光伏组件和储能系统的容量。根据光伏系统?储能联合运行的特点,考虑运行过程中储能能量的动态变化过程,以储能单元的技术特性为约束,提出以负荷缺电率(loss of power supply probability,LPSP)和能量溢出比(energy excess percentage,EXC)为考核指标的光伏、储能容量的联合配置方法。在给定案例条件下,考虑了阀控铅酸电池、锂离子电池和全钒液流电池3种类型,分别对3种电池储能进行了容量配置,并以初始投资最小为目标,计算最优光储容量配置。结果表明,在相同配置情况下,采用全钒液流电池系统供电可靠性较高、经济性较好,而在满足指标要求下,采用阀控铅酸电池系统初始投资最小。

关键词(KeyWords)： 独立光伏系统;储能;负荷缺电率;能量溢出比;容量配置
