Study of standalone photovoltaic system

Abstract

This thesis presents a comprehensive study on the design, sizing, and control of standalone systems. It begins with the modeling of a photovoltaic generator (PVG) managed by a boost converter to track the Maximum Power Point (MPP) using various techniques such as perturb and observe (P&O) algorithms, fuzzy logic (FL), and Particle Swarm Optimization (PSO). A battery-based storage system is introduced, controlled by a bidirectional DC/DC converter with a PI regulator, along with an integrated Energy Management System (EMS). The thesis also underscores the importance of precise system sizing through the study of a real autonomous solar system, and provides the design and simulation of a complete system powering an AC load.
