Maximum power point tracking using fuzzy logic based controllers compared to P&O technique in photovoltaic generator

Abstract

The use of renewable energies has grown significantly in the world. Given the growing demand for electrical energy. In this paper we discuss the optimization of the production of a GPV by two different techniques MPPT. In order to make a full operation of photovoltaic array, its compulsory to inaugurate a protocol or an algorithm to help extract, track and maximize the available power, this technique is called Maximum Power Point Tracking (MPPT).A several number of technique has been presented, such as the classic techniques; Perturb and Observe (P&O) [1], and incremental conductance [2], which are largely used mostly due to their simplicity of implementation and less complexity. In this paper, a Fuzzy Logic Controller (FLC) based MPPT technique [3] is compared to conventional P&O technique. The simulation in MATLAB/Simulink environment reveals the superior performance of FLC based technique over P&O method.
