Contribution à l’optimisation d’une chaine de conversion d’énergie photovoltaïque

Abstract

This work focuses on the optimization of photovoltaic MPPT chain, this axis is an important flaws in this field. For this we proposed a new approach MPPT and make a comparison with other approaches known in the literature. Simulation results show that our algorithm is efficient and rather complex than the other algorithms. However has a study on the stability of the DC-DC converter offer a more flexibility and stability during variation of the maximum operating point.
