基于Matlab/Simulink仿真的晶硅材料太阳电池建模

Modeling of crystalline silicon solar cells based on Matlab/Simulink simulation

以改进后的晶硅材料太阳电池的数学模型为基础,通过Matlab/Simulink仿真软件搭建出一个具有较强实用性的太阳电池模型。与现有的太阳电池模型相比,该模型忽略了二极管的反向漏电流对电池的影响,以使其能更好地模拟出真实光伏电源的输出特性。该模型可以通过调节光照强度和温度等参数,在不同的环境下进行仿真。将仿真结果与工程中常用的简化模型Solar Cell模块仿真数据进行对比,两者的相对最大误差小于6%,可以为后续的实用提供参考价值。

Based on the improved mathematical model of crystalline silicon solar photovoltaic cell, a photovoltaic cell model was built by Matlab/Simulink simulation software. Compared with the existing models, the effect of the reverse leakage current of the diode on the battery was ignored by this model, so that the output characteristics of the real PV power supply could be better simulated. The model could be simulated in different environment by adjusting the light intensity and temperature. Finally, the simulation results were compared with the simplified model cell solar module simulation data, and the relative maximum error was less than 6%, which could provide reference value for the follow-up.
