    Ensuring sustainability in Libya with renewable energy and pumped hydro storage
    (Nicolaus Copernicus University, 2024) Elmnifi, M.; Khaleel, M.; Vambol, S.; Yeremenko, S.; Nassar, Y.F.; Dzhulai, O.
    A radical transformation is occurring in the global energy system, with solar PV and wind energy contributing to three-quarters of new electricity generation capacity due to their affordability. This shift towards renewable electrification of energy services, such as transportation, heating, and industry, will gradually replace fossil fuels in the coming decades. This paper highlights Libya's potential to achieve energy self-sufficiency in the twenty-first century. In addition to its fossil energy resources, Libya possesses favourable conditions for solar, wind, and moderate hydroelectric energy. The solar energy potential alone is approximately 100 times greater than what is needed to support a fully solar-powered system that provides energy consumption similar to developed countries for all Libyan citizens, without relying on fossil fuels. Moreover, Libya's Green Mountain range offers substantial opportunities for low-cost pumped off-river hydropower storage. Therefore, the integration of solar and wind energy, complemented by hydropower and battery storage, is likely to be the primary pathway for the rapid growth of Libya's renewable electricity sector. © 2024 Nicolaus Copernicus University.

    The Impact of SMES Integration on the Power Grid: Current Topologies and Nonlinear Control Strategies
    (Springer Science and Business Media Deutschland GmbH, 2024) Khaleel, M.; Gulbudak, O.; Ayed, S.K.; Mustafa, M.A.S.; Majdi, H.S.; Habeeb, L.J.; Elmnifi, M.
    Superconducting magnetic energy Storage (SMES) has recently provided fast and effective relief on the power grid (PG). In addition to that, the power quality (PQ) issues affecting the PG continue to receive special attention. There is no doubt that the PQ issues are an important point concerning the effect on the power grid (PG) utility. In this context, this manuscript aims to demonstrate in-depth the configurations, characterization, and properties of SMES as a robust energy storage (ES) technology. The main objective of SMES can be achieved by delivering excellent performance to support the demand load. From this perspective, current topologies SMES-PG interconnection are developed to evaluate the effectiveness and performance-enhancing while supplying efficient energy using non-linear control strategy including sliding mode controller strategies, partial feedback linearization, control strategy, hysteresis controller strategy, robust controller strategy, and predictive controller strategy. To conclude, this manuscript investigates in detail to determine the applications of SMES-PG interconnection and future scope. © The Author(s), under exclusive license to Springer Nature Switzerland AG 2024.

    An Optimization Approaches and Control Strategies of Hydrogen Fuel Cell Systems in EDG-Integration Based on DVR Technology
    (International Information and Engineering Technology Association, 2024) Khaleel, M.; Yusupov, Z.; Alderoubi, N.; Habeeb, L.J.; Elmnifi, M.; Mohammed, A.; Majdi, H.S.
    Electrical Distribution Grid (EDG) will be required to further enhance PQ while also providing higher-efficiency electrical technology. The relationship between the elements of EDG and Hydrogen Fuel Cell Systems (HFCS) was thoroughly examined in this study. This investigation, emphasizes the controller techniques of DVR technology and HFCS interface, as well as the connected converter topology such as multi-input single-output dc-dc converters topology, voltage double boost converters topology, and high step-up coupled inductor converter topology, could contribute to decreasing the danger of EDG by limiting the consumption of fossil fuels for power-generation, reducing the emission of hazardous. Moreover, according to what the research discussed HFCS with EDG interfacing is based on DVR technology. The article delivers several novel contributions to the realm of electrical engineering and renewable energy integration. It presents a pioneering integration of hydrogen fuel cells with DVR technology to enhance power delivery reliability and efficiency within electrical distribution grids. This work introduces advanced optimization algorithms aimed at im-proving the operational efficiency, lifespan, and cost-effectiveness of hydrogen fuel cells. Furthermore, it develops robust control strategies for dynamic voltage restoration, crucial for maintaining stable voltage levels under variable loads. The article also includes detailed simulation models to provide empirical support for the proposed strategies and assesses both the environmental impacts and scalability aspects of the system. These innovative elements ensure that the article contributes significantly to the existing body of knowledge, providing practical solutions and theoretical insights that could influence future research and development in the integration of renewable energy technologies within electrical distribution systems.
