Bond graph based modeling for parameter identification of photovoltaic module.

This work introduces a mathematical model for photovoltaic module based on manufacturing datasheet, ambient temperature and solar irradiation. This mathematical model of photovoltaic module is applied to its single diode equivalent electrical circuit using bond graph methodology. The developed model allows identifying the PV module's five parameters without going through an iterative process. In this work all the parameters of the photovoltaic module are given as a function of both ambient temperature and recorded solar irradiation. To prove the accuracy of the proposed model comparisons are done at standard test conditions as well as at random climate conditions using experimental data. Obtained results show that the proposed bond graph based identification method is very effective when fast computation of PV model parameters is needed. [ABSTRACT FROM AUTHOR]
