Intelligent Control of a Photovoltaic Generator for Charging and Discharging Battery Using Adaptive Neuro-Fuzzy Inference System

Abstract EN

This paper presents a method of intelligent control of a photovoltaic generator (PVG) connected to a load and a battery.

The system consists of charging and discharging a battery.

An intelligent algorithm based on adaptive neuro-fuzzy inference system (ANFIS) is presented in this work.

It performs two separate tasks simultaneously.

First, it is used as a PVG Maximum Power Point Tracking (MPPT) command.

This same algorithm is used secondly for protecting the battery against deep charges and discharges.

A regulation of the DC bus voltage is also carried out by means of a PI corrector for a good supply of the load.

The simulation results under MATLAB/Simulink show that the method proposed in this work allows the PV system to function normally by charging and discharging the battery whatever the weather conditions.
