    Mechanical wind pumping system based on hydropumped storage
    (IEEE, 2022) Achour, Djalloul; Kesraoui, Mohamed
    In this paper, a new pumping system where a controlled storage has been integrated to a classical mechanical wind pumping system is proposed. The new system consists mainly of a wind turbine, a controlled storage and a piston pump. The objective of this developed system is to improve the standard system global power efficiency. First, a literature survey over what has been done up to now on wind pumping and pumped storage is presented. The details of the proposed system design are given. Then, the advantages of this new system compared to a classical one are shown. Finally, the developed wind pumping system and the standard mechanical wind pumping system were simulated in order to prove that the proposed system has the best results in terms of power efficiency and stored water

    Strategy of detecting abnormal behaviors by fuzzy logic
    (IEEE, 2017) Chebi, Hocine; Acheli, Dalila; Kesraoui, Mohamed
    This work falls within the framework of the video surveillance research axis. This work falls within the scope of video surveillance. It involves a link between automatic processing and problems related to video surveillance. The job is to analyze video streams coming from a network of surveillance cameras, deployed in an area of interest in order to detect abnormal behavior. Our approach in this article relies on the new application and the use of fuzzy logic in the case of division and fusion of the crowd. The detection of these behaviors will increase the speed of response of the security services in order to perform accurate analysis and detection of events in real time

    New concept of wind pumping system : introduction and state of the art
    (IEEE, 2020) Achour, Djalloul; Kesraoui, Mohamed
    In this paper a new concept of wind pumping system that combines the advantages of the mechanical wind pumping system and those of the electrically powered one is proposed. The system consists mainly of a wind turbine, a DC machine and storage facility. The whole system will be controlled in a goal to improve the total power efficiency. First, a literature survey over what has been done up to now on wind pumping is presented. The details of the proposed system design are given. Then, the advantages of the proposed system compared to actual ones are shown. Then since this system is a part of an accepted PRFU national research project 2020-2024, an Algerian windy site for its intended implementation is suggested. Finally the three wind pumping systems are simulated to prove that the developed one has the best results

    Grid Connected Solar PV System: Modeling, Simulation and Experimental Tests
    (Elsevier, 2016) Kesraoui, Mohamed; Lazizi, Aldjia; Chaib, Ahmed
    In this paper a solar PV system is modeled, simulated and experimentally tested. Mathematical and electrical models have first been presented. A theoretical background which introduces the topic has been presented. The system's different components have also been described. Then a simulation work of the current voltage (I-V) characteristics and efficiency by using MATLAB/IMULINK has been performed. Finally a PV system installed in the Institute of energy systems and electrical drives at the Technical University of Vienna has been tested. Many disturbances and cases like blackout, load disconnection and islanded system have been investigated. In this mainly experimental work, three test situations have been performed and the corresponding measurements have been recorded. Results that have been obtained showed that the grid connected PV system responds adequately to all the applied disturbances
