Modeling of Photovoltaic Panel using Matlab/Simulink and application of P & O Algorithm P & O Algorithm

In this paper, we propose a novel Model of Photovoltaic (PV) System including a PV panel and a Buck-Boost Converter. The latter is controlled by a Perturb and Observe Algorithm and connected to a resistive La. This Model is performed employing Matlab/Simulink. The obtained simulation results which are the different curves of temporal variation of the output Power of the used PV panel show the efficiency of the P & O Algorithm in tracking the MPP and this in the case of unchanging insolation and the other case where this insolation is varying over the time.
