Modélisation et commande d’un panneau photovoltaïque dans l’environnement PSIM
Résumé
The objective of this work is to make a model of photovoltaic cells (PV) dedicated to teaching renewable energy using PSIM software. This model is based on ratings provided by the manufacturer as: open circuit voltage, short circuit current, voltage and current corresponding to the maximum power point. So the resulting model has a better approach and takes into account the influence of different physical parameters including temperature, irradiation, series resistance, shunt resistance and saturation current of the diode. After a general presentation of the photovoltaic conversion chain, the article details, at first, the modeling of a photovoltaic panel. Secondly, we focus on the implementation of a MPPT command for controlling the DC / DC to operate the PV array at maximum power (MPP).
