Comparative Study Between MPPT Control By Incremental Conductance And Perturb And Observe Under Different Climatic Conditions.

[Full Text]






MPPT, GPV, Incremental conductance, Perturb & Observe, Matlab-Simulink.



The aim of this paper is to study and analyze the ability of the MPPT control designed for a photovoltaic system to ensure the search and continuity of the maximum power point at the output of a photovoltaic generator, under standard test conditions as well as during climatic changes (Illumination and temperature). For comparison, we have dealt with two different methods, the incremental conductance and the perturbation and observe. Both methods allowed the system to maintain its maximum power point in each case of study but with some differences. For this, we chose MATLAB/Simulink as the platform used to perform simulations of all the study cases.The emphasis was put on obtaining a system that presents a better adaptation between its different components: photovoltaic generator (GPV) and load. The PV system used in this study consists of a photovoltaic array that - under standard test conditions (T=25°C and G=1000W/m²) - is characterized by a peak power of 59.5 W, an optimal voltage of 17.5V and a current of 3.4A.
