Perturb and Observation MPPT algorithm for the performance of Solar Photovoltaic System

Abstract

The Maximum Power Point Tracking is a technique used in power electronic circuit to improve the efficiency of photovoltaic systems . Several works and many papers have suggested different methods for extracting maximum power point. The aim of this work is to develop and realize the performance of the Photovoltaic system using Perturb and Observe algorithm. The first part of the work is devoted to the study of the components constituting the global photovoltaic system namely: the photovoltaic generator and the DC-DC converter. The PV generator is modelled by the mathematical equations and its current-voltage characteristics and the power-voltage characteristics are simulated taking in to account the temperature and sun's irradiance. The second part is detailed the MPPT method of Perturb and Observe using the DC-DC converters. The simulation results are designed in the MATLAB / SIMULINK environment where demonstrated the efficiency of the photovoltaic system when using Perturb and Observe MPPT algorithm.
