    Comparative study of classical and metaheuristic MPPT control of the stand-alone photovoltaic system
    (National Higher School of Technology and Engineering - ANNABA, 2024) BENGAOUER Chaima; BENKHALED Souad Nour El Houda; DEKHANE Azzeddine (Encadrant); BOUZITOUNA Abdallah (Encadrant)
    This dissertation explores optimizing of photovoltaic solar energy, essential in today's climate change context. Due to various internal and external factors, the performance of solar panels can be limited. Maximum power point tracking (MPPT) techniques are used to maximize the power extracted. This work compares two MPPT methods: Perturb and Observe (P&O) and Particle Swarm Optimization (PSO). Using MATLAB Simulink, we evaluate their performance, efficiency, complexity and adaptability to environmental variations. The structure of the dissertation includes the study of stand-alone photovoltaic systems, DC-DC boost converters, the development of simulation blocks, and the comparative analysis of results to determine the most efficient method.

    Sliding Mode MPPT Controller for Photovoltaic Systems: Performance, Efficiency and Stability Analysis
    (National Higher School of Technology and Engineering - ANNABA, 2024) BACHIRI Asma; CHEURFI Ghada Imane; DEKHANE Azzeddine (Encadrant); BOUZITOUNA Abdallah (Encadrant)
    Solar technologies are developing as a possible answer for meeting the rising need for sustainable energy, turning solar energy directly into electricity. However, the efficiency and profitability of solar power systems are dependent on their capacity to properly absorb and convert solar energy, which is difficult owing to the nonlinear nature of solar generators and the fluctuation of weather conditions. Effective management of this energy source necessitates major technological breakthroughs, particularly in energy conversion and storage. This emphasizes the crucial necessity of the maximum power point (MPPT), which improves solar panel performance by continually modifying the operating point in response to environmental fluctuations to maximize energy output. In this context, this work proposes a robust MPPT technique using a double integral sliding mode controller (DISMC) for a stand-alone photovoltaic system, whose aim is to design a new sliding surface to improve the transient response and reach MPP quickly under varying conditions. Modeling of the stand-alone photovoltaic system and simulations were carried out using Matlab/Simulink.
