光伏扶贫电站光-储协同配置方法研究
|
摘要
针对光伏扶贫电站的应用场景,以负荷失电率和能量溢出比作为约束指标,建立光-储扶贫系统的储能配置计算模型。在满足供需平衡的基础上以提高光伏组件的利用率,减小储能配置成本为目标进行求解。最后进行仿真分析,对比在的不同类型的储能电池参数下的配置容量和成本,证明基于负荷失电率(LPSP)和能量溢出比(EXC)作为技术指标的光伏储能协同配置策略的有效性。
Aiming at the application scenario of photovoltaic poverty alleviation station,the energy storage allocationcalculation model is established with load loss rate and energy spillover ratio as constraints. On the basis of meeting the balance between supply and demand,the objective is to improve the utilization ratio of photovoltaic modules and reduce the allocation cost of energy storage. Finally,the simulation analysis is carried out to compare the allocation capacity and cost of different types of energy storage batteries which proves that the collaborative allocation strategy of PV-storage based on LPSP and EXC as technical indicators is effective.
