摘要
基于均匀光照下光伏电池输出特性数学模型,推导建立了串联光伏阵列在复杂受光条件下的输出特性数学模型,并利用Matlab/Simulink软件进行仿真,研究了光伏阵列在复杂光照下的输出特性变化规律。结果表明,在复杂受光条件下,光伏阵列的电气输出特性会发生显著变化,输出功率明显降低。该研究为后续MPPT算法和光伏阵列设计提供理论分析基础。
Based on the mathematical model of photovoltaic cell output characteristics under uniform light conditions,the mathematical model of output characteristics of series photovoltaic arrays under complex light conditions is deduced and established.Simulated by Matlab/Simulink software,the variation rule of output characteristics of photovoltaic array under complex illumination is studied.The results show that under complex light receiving conditions,the electrical output characteristics of photovoltaic array will change significantly,and the output power will be reduced obviously.This research provides a theoretical basis for the subsequent MPPT algorithm and photovoltaic array design.
