Oman's Vision 2030-2040 outlines a transformative shift towards sustainable energy, reducing the oil sector's GDP contributions and increasing renewable energy consumption. The vision includes scaling up clean hydrogen production significantly, aiming to position Oman as a regional leader in sustainable energy. The Oman Electricity Transmission Company is actively integrating large-scale renewable projects like solar and wind expansions, but faces challenges related to grid stability due to the intermittent nature of renewable energy sources. Energy Storage Systems (ESSs) are seen as crucial solutions to enhance renewable energy integration, reduce operational costs, and stabilize the grid. Various ESS technologies, such as lithium-ion batteries, Pumped Hydro Energy Storage, and Compressed Air Energy Storage, offer different advantages and challenges. Literature reviews explore advanced planning frameworks for integrated energy systems, multi-objective optimization for energy sharing networks, and the need for future research to address limitations in current models and enhance convergence robustness. Overall, Oman's vision highlights the country's commitment to a sustainable energy future and the importance of technological advancements and research in achieving its ambitious goals.
