    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

    Solution of the economic dispatch problem using global algorithm
    (2021) Benmissoum, Abdellah; Khellas, Oussama; Recioui, A. (Supervisor)
    The concept of a microgrid system, when put in simple words, is a small-scale generation and deployment of power to a small geographical area in order to avoid transmission losses and maintain an uninterrupted power supply. It has been a mandatory protocol to implement the available renewable energy sources (RES) in order to minimize the emission of harmful pollutants to the atmosphere from the combustion of the fossil fuels. Economic load dispatch (ELD) deals with the optimal sizing of the distributed energy resources (DERs) by minimizing the fuel costs. Emission dispatch does the optimal sizing of the DERs sources by minimizing the number of pollutants released in the atmosphere. A multi-objective Combined Economic- Emission Dispatch (CEED) does the optimal DER sizing providing a compromised solution of minimizing both the fuel costs and pollutants emission. This work performs all ELD, emission dispatch and CEED on an islanded and renewable-integrated microgrid separately and a ten-unit Algerian Network using a recently developed novel Improved Harmony Search Algorithm (IHSA).
