Abstract

The model parameters of photovoltaic (PV) cell depend on the environmental conditions, especially are function of the temperature and the irradiance values of the site where the panel is placed. In this paper the performances of PV cells/panels are analysed related to the different temperature and irradiance levels by using the circuit sensitivity. Therefore the model parameters of the equivalent circuits for PV cells and their typical connections are modelled by first order sensitivity relations. LabViEW and MatLab software procedures are implemented in order to prove the theoretical models, and to provide numerical examples taken from real case on PV cells.

光伏电池模型参数灵敏度分析与实验验证
光伏电池的模型参数取决于环境条件,特别是太阳能电池板放置地点的温度和辐照度值的函数。本文利用电路灵敏度分析了不同温度和辐照度对光伏电池/面板性能的影响。因此,PV电池等效电路及其典型连接的模型参数采用一阶灵敏度关系建模。通过LabViEW和MatLab软件程序对理论模型进行了验证,并给出了光伏电池实际案例的数值算例。
