Two Combined Model Mppt Algorithms For Stand Alone Photovoltaic Systems

Résumé: Maximum Power Point Trackers (MPPT’s) play an important role in stand alone photovoltaic systems. MPPT’s find and maintain operation at the maximum power point, using an MPPT algorithm. Many MPPT algorithms have been proposed in the literature. The MPPT techniques using microprocessors are favored because of their flexibility and compatibility with different PV module. The efficiency of these MPPT algorithms is drops in cases of rapidly changing atmospheric conditions. The incremental conductance solves this problem. In the other way, we find that the constant voltage algorithm is the simplest and is more effective than the incremental conductance in case of low solar irradiance condition. This paper combines the two models MPPT control algorithm, the constant voltage and the incremental conductance under different solar irradiance levels. Firstly, a novel model is proposed to predict the PV module performance for engineering applications and compared with the Walker model. A MSX60 PV, BPSX150 PV and PB585 PV modules are selected to proof the performance of the proposed model. Next, the combined two model MPPT algorithm is applied at various irradiations solar. Finally, a model of Cuk converter is built in order to verify the performance of proposed MPPT algorithm.
