Abstract EN
Photovoltaic solar energy is one of the most important renewable energy sources.
However, the production of this energy is nonlinear and varies depending on atmospheric parameters.
Therefore, the operating point of the photovoltaic panel (PV) does not always coincide with the maximum power point (MPP).
A mechanism that allows the research of the maximum power point known as maximum power point tracking (MPPT) algorithm is then needed to yield the maximum power permanently.
This paper presents an intelligent control technique based on the ESC (Extremum Seeking Control) method for MPPT under varying environmental conditions.
The proposed technique is an improvement of the classical ESC algorithm with an additional loop in order to increase the convergence speed.
A detailed stability analysis is given not only to ensure a faster convergence of the system towards an adjustable neighborhood of the optimum point but also to confirm a better robustness of the proposed method.
In addition, simulation results using Matlab/Simulink environment and experimental results using Arduino board are presented to demonstrate that the proposed modified ESC method performs better than the classical ESC under varying atmospheric conditions.
