    Analysis of the disturbances in distribution networks using matlab and ATP
    (2011) Boutora, S.; Bentarzi, Hamid; Ouadi, A.
    The capacitance bank is generally used for compensation in a distributed power grid, if the latter is connected to the utility. An islanded power grid is a distribution grid disconnected from the utility. It can undergo a disturbance namely the ferroresonance phenomenon if the capacitance bank has a non adequate value. In this paper, a study of an islanded power grid is attempted to show the effect of the reconfiguration of the capacitance bank on the ferroresonance. A simulation of the circuit is conducted using Simulink/ MATLAB. In another part of this work, an example of overvoltage study in a distribution medium network using ATP is also presented

    Improving the efficientcy of photovoltaic power systems
    (2016) Bouznada, Khaled; Obeidi, Baha Eddine; Boutora, S.
    With the increase of the world’s population day by day, the demand of energy is increasing accordingly. Although oil and gas are the main energy resource in the world currently, experts say that this wouldn’t be the case in the next decades. The focus on renewable energies has increased and it gained the attention of nations around the globe. Solar energy and exactly photovoltaic (PV) systems are considered as one of the main energy resources especially in warm countries. One challenge is to have systems that operate with high efficiency. Our thesis reviews different methods to increase their efficiency. The main methods, which are, solar tracking, maximum power point tracking and cell cooling; are detailed and simulated using simulation dedicated software. Results show the significant improvement in PV systems efficiency when applying these methods.
