Abstract


This work presents a hybrid soft-computing methodology approach for intelligent Maximum Power Point Tracking (MPPT) techniques of a photovoltaic (PV) system under any expected operating conditions using Artificial Neural Network-Fuzzy (Neuro-Fuzzy). The proposed technique predicts the calculation of the duty cycle ensuring optimal power transfer between the PV generator and the load. The Neuro-Fuzzy hybrid method combines Artificial Neural Network (ANN) to direct the controller to the region where the MPP is located with its reference voltage estimator and its block of neural order. After that, the fuzzy logic controller (FLC) with rule inference begins to establish the photovoltaic solar system at the MPP. The obtained simulation results using MATLAB/Simulink software for the proposed approach compared to ANN and the Perturb and Observe (P&O), proved that Neuro-Fuzzy approach fulfilled to extract the optimum power with pertinence, efficiency and precision.
