Abstract

Photovoltaic is one of the most important renewable energy sources. The output characteristics of a photovoltaic generator are influenced by climatic factors (insolation and temperature). So to extract maximum power, photovoltaic system uses different techniques that are called (MPPT). Various MPPT methods have been developed and proposed in literature. In this paper, we developed two approaches: P&O and short circuit methods. The attention here mainly is focused on experimental validation in real-time using a test bench composed by a resistive load powered by a photovoltaic generator (PVG) formed by ten photovoltaic panels via a boost chopper for the adaptation between the source and the load. The control part is provided by a computer incorporating a card DS1104 running environment Matlab/Simulink for visualization and data acquisition. This work is to see and compare experimentally the dynamics of the PV system under a random insolation scenario to improve the energy efficiency of the system. Also, a comparative study is made between these two types of methods. These results show clearly the effectiveness of our control with a very good performance.
