    Design and simulation of low distortion current mode control power factor correction converter
    (IEEE, 2020) Bouaraki, Mouloud; Dekhandji, Fatma Zohra; Recioui, Abdelmadjid
    The spread of switched-mode power supplies for DC appliances to fulfill effectiveness and performance goals has been met with the growth of industry legislation and recommended practices for power quality assurance (e.g., IEC 61000-3-2). The generation of harmonic content induced by non-linear loads is an undesirable side effect to the conversion of electrical energy in the network which in turn lowers the power factor leading to greater power consumption and losses throughout the grid. In this project, an Active Power Factor Correction (PFC) circuit based on boost converter with its control system will be introduced, which is a relatively simple and low-cost circuit. The design and simulation of boost converter with Average Current Mode control in Continuous Conduction Mode (CCM) will be presented in order to achieve a high switching frequency and power factor, with a low total harmonic distortion and high efficiency

    Etude d'un entrainement à double alimentation pour turbine éolienne à vitesse variable : application sur un site à Tindouf
    (2012) Bouaraki, Mouloud
    Ce mémoire a pour objectif d'une part l'étude et la commande d'une génératrice asynchrone à double alimentation(MADA) intégrée dans un système éolien et d'autre part le dimensionnement et l'optimisation technico-économique d'un système éolien hybride appliqué sur la région de Tindouf. Nous avons présenté en premier lieu un état de l'art sur les aérogénérateurs, l'étude et la modélisation de la MADA ont aussi été présentés, suivi par l'étude et la modélisation de la partie mécanique de l'éolienne. Nous avons aussi présenté la commande vectorielle en puissances actives et réactives statoriques de la MADA intégrée dans un système éolien, ainsi que sa simulation en utilisant le logiciel Matlab Simulink. Dans la dernière partie de notre mémoire, nous avons présenté le potentiel éolien de notre pays, suivi par le dimensionnement d'un système éolien hybride alimentant en énergie électrique un village isolé dans la région de Tindouf. A l'aide du logiciel Homer, nous avons étudié la faisabilité et l'optimisation technico-économique du système complet

    Joint economic and emission load dispatch for the Algerian grid via an improved harmony search algorithm
    (Springer, 2023) Bouaraki, Mouloud; Dekhandji, Fatma Zohra; Recioui, Abdelmadjid; Benmissoum, Abdellah; Khellas, Oussama
    Renewable energy sources (RES) have been very popular as they reduce the release of damaging toxins to the air contrary to fossil fuel combustion. The economic load dispatch (ELD) issue looks for the optimal dimensioning of the RES to lessen the fuel cost while Emission Dispatch (ED) is concerned with the best dimensioning of the RESs to decrease the quantity of the produced pollutants. A multi-purpose Joint Economic-Emission Dispatch (JEED) seeks the best RES dimensioning by compromising the fuel fee and toxin release simultaneously. In this paper, a JEED problem is solved for a ten-unit Algerian Network using a recent optimization algorithm named Improved Harmony Search Algorithm (IHSA). The obtained results suggest that the considered JEED problem proves to be more practical than when ELD and ED are dealt with separately. Also, an enhancement in terms of economic and emission dispatch is obtained for the considered case. This work also witnesses on the superiority of the IHSA over state of art approaches

    Load Balancing in Smart Grids using Multi- Objective Evolutionary Optimization
    (Université M'hamed Bougara de Boumerdès, 2021) Bouaraki, Mouloud; Dekhandji, Fatma Zohra; Abdi, Lina Amel; Recioui, AEM
    The work deals with the balance between the supplied and consumed power in a residential area. An optimization task is formulated and solved. The extension of the optimization task formulation to include renewable sources is also provided. It is shown in the results that using the deployed optimization technique, a significant reduction in the energy usage cost and the waiting time of the appliances (delay) for residential consumers can be achieved. This work can be used in smart home and smart cities applications.
