Modélisation et simulation comportementale des systèmes à energie renouvelable par VHDL-AMS

Abstract

The research presented in this thesis aims to develop models to improve the performance of renewable energy systems. We began by presenting two algorithms MPPT of a photovoltaic system, which can makes the panel works to its maximum power point. We then developed a model of the PEM fuel cell that can show the effect of the environment (temperature and pressure) on the characteristics of the fuel cell. We also developed a model of the absorber tube, which allows to predict its effectiveness and takes into account: the period and the locus of the installation, the average solar radiation, the angle of incidence, the rate of heat transfer fluid and the wind speed. Finally, we proposed a prototype system of electricity production composed of an absorber tube, an Alpha Stirling engine, synchronous machine and a resistive load. Control techniques and models developed in the context of this work are verified by simulation using the Simplorer software and the VHDL-AMS language.
