Abstract
This paper presents the system allowing the extraction of maximum power from a sun based on solar photovoltaic module and backstepping control based on a P&O MPPT algorithm for a DC-DC buck converter. The aim of this research work is to determinate quickly the optimal PV Module working point which allowed to extract the maximum power. This work, based on a usage of a DC-DC buck converter to control the working point by adjusting PV voltage trough a duty cycle. In order to achieve our goal, we used the combination of perturb and observe (P&O) algorithm and DC-DC buck converter with backstepping control. This model was implemented in Matlab/Simulink software, the results of simulation prove its effectiveness in term of maximum power tracking dynamics for different irradiance and temperature profiles.
Highlights
Since the industrial revolution, the energy mix of most countries across the world has become dominated by fossil fuels [2]
We present the PV Module model and its behaviour for variation of radiation and temperature, in the third section we present the DC-DC Buck converter model, in the fourth section, we present the DC-DC Buck converter control design using backstepping technique, after that in the fifth section, we present our Maximum Power Point (MPPT) algorithm based on the principal of Perturb and Observe (P&O), sixth section we give the simulation results of the PV conversion control, followed by conclusion [1]
This article brings to light the steps taken to model the photovoltaic module from equivalent circuit and the equations of a solar cell
