Photovoltaic Panel Modeling in MATLAB® Environment
MetadataShow full item record
This article is focused on the original photovoltaic panel model identification method. The method is based on the measured characteristics for given irradiation. The system can automatically create a mathematical model for a particular panel, and a specific temperature. Attention is paid to the approximation error progress, which is at minimum in the Maximum Power Points (MPP). During the application of well-known Shockley’s equation to the entire panel the nonlinear and parametric power losses are corrected. This approach provides an accurate approximation with good agreement with measured data. The method can be applied to any measured photovoltaic panel. The model identification procedure and its use are demonstrated on the example of a particular panel. A detailed methodology for application is presented for users of the MATLAB environment.
