Improvement Analyses of a Photovoltaic System Controlled by the MPPT Command Perturb and Observe

Abstract

This paper will discuss the study, analysis and simulation of a photovoltaic (PV) electrical system performance adapted to a Maximum Power Point Tracking (MPPT) command for ensuring the pursuit of the maximum power supplied by the generator.To attain this purpose, the focus was on obtaining a system which presents a better adaptation between its various components: Photovoltaic generator (GPV) and load.The proposed approach is a (MPPT) command based on the algorithm perturb and observe, the role of which is to fix the optimal tension to the (GPV) output.The control carried out allows searching for the Maximum Power Point (MPP). The results obtained show that the controller used manages to force the system to operate at a maximum output power of (GPV) independently of the weather conditions and of the variation of the load.In this analysis, the conceived system is a (GPV) of the type producing, under standard test conditions (STC), a peak power of , an optimal current of 4.41A and an optimal tension of .
