    Design and simulation of sun tracker with MPPT
    (2016) Hassani, Islam; Bourezg, A. (Supervisor)
    Solar electricity is seen as being a significant source of renewable energy.The photovoltaic generator is a source characterized by only one point of operation where the generated power is maximum called maximum power point(MPP). Unfortunately that point moves according to the weather conditions (temperature and rradiance) and needs a controller to track it. Many MPPT techniques were proposed such as perturb and observe (P&O), Incremental conductance (InC), the fractional open circuit voltage (FOCV) ,fractional short circuit current (FSCC). This work presents an improved sun tracker controller for PV systems. An mproved P&O algorithm using a microcontroller to achieve this objective. The developed MPPT uses the Sun tracker to extract the maximum power. The simulation results show that the response of the proposed design is faster than the P&O algorithm without sun tracke. i

    A Mathlab-based simulation of PV-System integrated into a grid
    (2016) Ghazli, Wissam Abdelfetah; Rouag, Fadi Elislam; Bourezg, A. (Supervisor)
    This project presents a simulation model of the electric part of a grid connected photovoltaic generator. The model contains a detailed representation of the main components of the system that are the solar array, Buck converter and the grid side inverter. A proper control of the DC/DC converter is developed in order to extract the maximum amount from the photovoltaic generator. The grid interface inverter transfers the energy drawn from the PV module into the grid by keeping common dc voltage constant. Modeling and control is carried out using the causal informational graph method. The simulation results under Matlab/Simulink show the control performance and dynamic behavior of grid connected photovoltaic system.
