光伏电站输出功率影响因素分析

Analysis of Factors Affecting the Output Power of Photovoltaic Plants

光伏电站输出功率是指含有电池储能的并网光伏发电系统给指定的负荷或储能电池传输功率的效率,与整个光伏电站的拓扑结构以及每个组件的效率有关。特别是对于一个需要频繁充放电的光伏发电系统而言,仔细计算整个系统的效率能够有效提高光伏电站的输出功率。文章介绍了光伏系统发电量、系统耦合以及光伏发电通过电网给电池充电的效率这3个因素对于光伏电站输出功率的影响。

The output power of photovoltaic power plant refers to the efficiency of the grid-connected photovoltaic power generation system with battery energy storage to the specified load or energy storage battery transmission power,which is related to the topology of the entire photovoltaic power plant and the efficiency of each component.Especially for a photovoltaic power generation system that requires frequent charging and discharging,carefully calculating the efficiency of the entire system can effectively increase the output power of the photovoltaic power plant.This article will influence the output power of photovoltaic power plants from the three factors of photovoltaic system power generation,system coupling,and the efficiency of photovoltaic power generation charging the battery through the grid.
