Abstract This paper proposes a simple and efficient method to estimate the parameters of the photovoltaic (PV) cells at standard test conditions (STC). The proposed method is based on developing a mathematical model for each parameter of the single-diode equivalent circuit of the PV cell. The models are formulated using Eureqa software based on thousands of training data collected from simulating the equations that represent the equivalent circuit behavior of the PV cell. Only the data provided by the manufacturer’s datasheet are needed to execute the models and evaluate the parameters. The performance of the developed models is then assessed by comparison with simulation data, Simulink library modules, experimental data, and various recent reported algorithms. The assessments have shown an overall efficient performance of the models to evaluate the equivalent circuit parameters for any poly and monocrystalline PV cell/module at STC. In addition, the models are in good agreement and, in some cases, have outperformed various algorithms presented in the literature in terms of the accuracy of predicting the I-V curve characteristics.

使用简单高效的数学模型估算光伏电池的参数

摘要 本文提出了一种简单有效的方法来估计标准测试条件（STC）下光伏（PV）电池的参数。所提出的方法基于为光伏电池的单二极管等效电路的每个参数开发数学模型。这些模型是使用 Eureqa 软件根据从模拟代表 PV 电池等效电路行为的方程收集的数千个训练数据制定的。仅需要制造商数据表提供的数据来执行模型和评估参数。然后通过与仿真数据、Simulink 库模块、实验数据和各种最近报告的算法进行比较来评估开发模型的性能。评估显示模型在评估 STC 任何多晶和单晶光伏电池/模块的等效电路参数方面具有整体高效性能。此外，这些模型具有良好的一致性，并且在某些情况下，在预测 IV 曲线特征的准确性方面优于文献中提出的各种算法。
