    Electricity transportation using HVDC technology for Algerian southern sun power plants
    (2023-08-01) Nedjem Eddine Benchouia; Mohammed SAAIDIA; Abdelghani GUECHI
    Algeria is worldly known as one of the big producers and exporters of fossil fuels. However, by developing an adequate energy policy, it could become one of the great sun power (SP) producers and exporters. Indeed with almost 2 million Km2 sunny superficies, the country detains enormous SP energetic potential funds. However, eventual powerful SP plants deployment could be done far to the southern Algerian desert which makes HVDC technology the best candidate for the transmission of produced electricity towards the north region where are the main industrial poles and the most populated regions for local consumption and eventually farther to the north for electricity exportation to the European countries. Theprospection work presented hereafter is a study on the feasibility of using HVDC technology for such possible projects according to country’s existingmeans and topographical and environmental characteristics.

    System reliability of corroded pipelines considering spatial and stochastic dependency in irregular zones
    (Elsevier, 2023-08-06) Nahal Mourad; Sahraoui Yacine; Chateauneuf Alaa; Khelif Rabia
    This paper presents a probabilistic methodology for assessing the system reliability of corroded pipelines subjected to spatial and stochastic dependency, taking into account irregular zones (elbows, weld joints, and flanges). The space-variant corrosion and residual stress are considered by the mean of Karhunen-Loève expansion in order to take into account spatial variability of residual stress and soil aggressiveness over the pipe's entire length. The failure probability is evaluated by a series system combination using Monte Carlo simulations. Finally, the proposed model is applied to gas pipeline crossing several soil types in order to show the effects of the main parameters of the system, where the irregular zones have a significant influence on the pipeline system reliability and that the developed model can provide valuable information for decision-makers to improve system reliability performance.

    An Overview Of Photovoltaic Power Plant (PV) Connection To HVDC Grid
    (IEEE, 2023) Nedjem Eddine Benchouia; Abdelghani GUECHI; Mohammed SAAIDIA
    Solar energy is considered one of the most important alternative and renewable energies for the production of electricity so solar power plants work to produce direct current, which is then converted into alternating current through DC-AC converters and linked to power transmission networks of alternating current. But since most of the large solar PV plants are built in areas far from the load, the world is moving today to transfer power directly from solar panels to high voltage HVDC grid, due to the advantages that HVDC provides such as lower transmission loss, low cost and higher efficiency compared to HVAC. In this paper, we present an overview of recent studies dealing with Photovoltaic Power Plant Connections to HVDC Grid and the comparison between these systems.

    Modeling, Optimization, and Techno-Economic Assessment of a Hybrid System Composed of Photovoltaic-Wind-Fuel Cell and Battery Bank
    (IIETA, 2023) Nedjem Eddine Benchouia; Kamilia Boucenna; Toufik Sebbagh
    Decentralized electricity production from renewable energy sources offers greater security of supply to consumers while respecting the environment. However, the random nature of these sources requires us to establish rules for the sizing and use of these systems in order to make the best use of them. Hybrid renewable energy sources can effectively meet the electric energy needs of the University of Skikda's various structures. This study examines the financial viability of a hybrid renewable-based system that is off the grid and proposed to supply several campuses of the University of Skikda in Algeria with the electricity they need. In order to achieve this, HOMER software is used to optimize and simulate the system under consideration. The results obtained recommend using a system made up of a wind turbine, solar panels, a battery bank, and a fuel cell that can produce electricity at a levelized cost of 0.193 €/kWh.

    One day ahead prediction of PV power production: case study of Oued-Elkebrit’s station (Algeria)
    (2020) Nedjem Eddine Benchouia; Mohammed Saaidia; Talal Belhouchat; Kaltoum Achibi
    The research work presented hereafter is based on a real recorded database of a PV plant in production and in connection with a classical electrical grid. Datasets were processed through two types of techniques. The first one, a classical type, is based on a predictive predefined model, however, the second one is an artificial intelligent method based on neural networks. Based on the carried out experiences, we proposed a new strategy to implement the proposed techniques. The results obtained through the two methods were compared which demonstrate the superiority of the AI method in terms of precision, generalization, and robustness. Obtained results for each method were recorded, analyzed, and compared.

    HVDC electricity transportation technology: feasibility study (Algeria)
    (2020) Nedjem Eddine Benchouia; Mohammed Saaidia; Lekhmissi Derardjia
    HVDC technology is gradually becoming a standard in electrical energy transportation. Even more, in some situations, it’s the best practical solution. The research work presented hereafter is dedicated to the exploration of the basic notions, the induced gains, the basic components, the basic and extended structures, the applications, and the real implemented projects of such technology. An overview of the research works concerned with the challenges of this expandable technology and an economic study of the deployment of real electrical transportation lines and their feasibility in Algeria are presented.
