    Data aggregation point placement optimization in Smart Metering Networks
    (JES, 2024) Grainat, Youcef; Recioui, Abdelmadjid; Oubelaid, Adel
    This study explores the application of Particle Swarm Optimization (PSO) and Ant Colony Optimization (ACO) within the framework of smart grids (SG), specifically for the optimal placement of data aggregation points (DAPs) across a network of 150 Z-wave smart meters distributed within various smart cities. The investigation aims to identify which of the two- optimization strategies offers a more cost-efficient solution while evaluating their performance in terms of transmission average latency (AL) and execution time (ET) efficiency. The results indicate that although ACO slightly edges out PSO in reducing overall costs in networks with a higher complexity and more DAPs, PSO demonstrates superior performance in execution speed, lower AL, and total cost, underscoring its viability for swift integration in smart metering infrastructures.

    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

    Pattern nulling of linear array antennas with mutual coupling effects using taguchi method
    (IEEE, 2012) Recioui, Abdelmadjid; Bentarzi, Hamid
    The purpose of the present work is to employ the Taguchi's optimization technique, which is a relatively new optimization technique, for null steering in the antenna radiation pattern by controlling only the element positions of a nonuniform linear array for a specified beamwidth and minimum achievable sidelobe level. As a practical part, an array of parallel dipoles is designed to account for the mutual coupling effects on the performance of the array in terms of directivity, sidelobe level and null placement. Illustrative examples are considered to impose single or multiple nulls in the antenna pattern at specific interference directions with the maximum side lobe level reduction of array antenna design
