摘要
为了提升光伏阵列的发电量,提出光伏阵列间距规划下的山地电厂发电量优化方法,合理设置光伏组件安装倾角和光伏阵列间距。建立光伏发电模型计算太阳辐照强度,并根据设计规范计算最小安装距离;根据当地的气象信息判断太阳能资源丰富度,确定出最佳光伏组件安装倾角;基于光伏系统仿真软件(PVsyst)以等量微增率最大为目标获得优化后的光伏阵列间距,考虑发电成本使山地电厂发电量达到最优。实验结果显示:随着光伏组件安装倾角增加,太阳能辐射量呈先增后减变化,倾角为41°时,辐射量达到最大值7960 MJ·m^(-2);光伏阵列间距影响光伏发电量、线路损耗和成本;当光伏阵列间距为12 m,光伏组件倾角为41°时,可有效兼顾光伏发电量、线路损耗和成本,获取最佳山地电厂发电量优化结果。
To improve the power generation of photovoltaic arrays,a method is proposed to optimize the power generation of mountain power plants under photovoltaic array spacing planning,and the installation inclination angle of photovoltaic modules and the spacing of photovoltaic arrays are reasonably set.A photovoltaic power generation model is established to calculate the solar radiation intensity,and calculate the minimum installation distance according to design specifications.The abundance of solar energy resources is determined based on local meteorological information and the optimal installation inclination angle of photovoltaic modules is determined.Based on photovoltaic system simulation software(PVsyst),the optimized photovoltaic array spacing is obtained with the goal of maximizing the equal incremental rate,and the power generation cost is considered to achieve the optimal power generation of mountain power plants.The experimental results show that as the installation inclination angle of the photovoltaic module increases,the solar radiation first increases and then decreases.When the inclination angle is 41°,the radiation reaches a maximum value of 7960 MJ·m^(-2).The photovoltaic array spacing affects photovoltaic power generation,line losses,and costs.When the photovoltaic array spacing is 12 m and the installation inclination angle of photovoltaic modules is 41°,it can effectively balance photovoltaic power generation,line losses,and costs,and obtain the optimal optimization results of mountain power plant power generation.
