摘要

The use of renewable energy resources is becoming increasingly critical for a sustainable power generation scenario on a global scale. Solar photovoltaics and wind are the most prominent potential renewable sources in Oman, according to the studies conducted in the zone. Various locations in Oman behaved differently depending on the region’s potential energy source. For instance, the Dhofar region has an annual average global horizontal irradiance of 6.1 kWh/m2/day and a wind speed of 5.9 m/s at a 10-meter anemometer height from the ground, respectively. The intermittency of renewable sources and the need for reliability in power systems lead to battery energy storage requirements. This study establishes the optimal hybrid system rating for a community load of 24.57 kW, considering multiple system configurations and producing 11.27 kg of hydrogen daily. Since renewable energy must replace fossil fuels in microgrids, this study compares the results with diesel generator-based systems. The study employs several criteria to identify the optimal solution, including meeting the load potential, minimizing the levelized cost of energy (LCOE), minimizing the levelized cost of hydrogen (LCOH) generation, calculating the net present cost, and calculating the CO2 emissions. The study region achieves a renewable energy fraction of more than 85%, with an LCOE of 0.421 $/kWh and an LCOH of 4.65 $/kg. Furthermore, we observed that the region has a high potential for green hydrogen generation, which can meet the country’s aim to improve the ratio of renewables in total energy supply and achieve sustainable development goals.
