Extracting Photovoltaic Panel Parameters for Model and Simulation Purpose

Résumé fourni par la source

The paper proposes an improved method to extract the parameters of a photovoltaic (PV) panel based on the data provided by the manufacturer in technical documents for the purpose of model and simulation. Manufacturers of PV panels, instead of I-V equation, usually provide only a few experimental data about electrical and thermal characteristics. Some of the parameters required for PV panel model cannot be found in manufacturer's datasheets. The two unknown parameters for modeling of a PV panel are series resistance Rs and parallel resistance Rp. Based on a published algorithm, which identifies the parameters of the nonlinear I-V equation by adjusting the curve at three points: open circuit, maximum power, and short circuit, this paper proposed an improved method to increase the accuracy and convergence speed of the previous algorithm by using two loops with golden-section search technique to determine the Rs and Rp.
