【摘要】：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。
[Abstract]:In order to improve the power supply reliability and photovoltaic utilization ratio of independent photovoltaic system, it is necessary to reasonably configure the capacity of photovoltaic module and energy storage system. According to the photovoltaic system? Considering the dynamic change process of energy storage energy during the operation process, considering the characteristics of energy storage joint operation, the photovoltaic (PV) with load power shortage rate (loss of power supply probability (loss of power supply) and energy overflow ratio (energy excess percentage (energy excess) is proposed, which is constrained by the technical characteristics of the energy storage unit. Joint allocation of energy storage capacity. In the given case, three types of valve-regulated lead acid battery, lithium ion battery and all-vanadium liquid flow battery are considered, and the optimal optical storage capacity is calculated with the aim of minimum initial investment. The results show that the power supply reliability and economy of the whole vanadium liquid flow battery system are higher and the initial investment of the valve-controlled lead-acid battery system is the least under the same configuration.
