为了快速且准确地求解光伏电池模型参数,进而求解局部阴影条件下光伏阵列的最大功率基准点值,采用高斯-赛德尔法,从工程实际出发,根据局部阴影下的光照情况,把光伏阵列模型分解成光照均匀条件下的多个新光伏阵列模型,利用光伏电池数据手册可以快速且准确地求解模型参数.仿真结果表明:高斯-赛德尔法能够快速且准确地求解拆分后模型的光伏阵列最大功率点基准值;该方法适用于光伏阵列在局部阴影条件下的输出特性和各个峰值点最大功率基准值求解问题.“,”This paper is aimed to quickly and accurately solve the parameters of photovoltaic (PV) cell model,in which the reference value at the maximum power point of the local shaded PV array is calculated.To address this issue,Gauss Seidel method is used.Based on the local shading conditions in practical engineering,the PV array model is split into a number of new PV array models under uniform light,the latter are supposed to be solved using the data manual of PV cell.The simulation results show that the reference value at the maximum power point of the split PV array model can be solved quickly and accurately by using the Gauss Seidel method.This would demonstrate that the method is suitable to model the output characteristics of PV array under local shading condition and solve its maximum power point value of each peak point.
