Özet

Research on renewable energy systems has accelerated in recent years due to the exhaustibility of fossil fuels and the damage they cause to the environment. Renewable energy sources such as wind, solar, and geothermal are used for energy production. In this study, a hybrid system design was created using wind, solar, and geothermal energy. The study offered the opportunity to produce electricity from low-temperature geothermal energy. Optimization of a hybrid system with geothermal energy in this study presents an innovative approach. Additionally, an energy storage system was added to the system for hydrogen production from the excess energy. The system met the required electrical load of 1983.040 MWh/yr and excess electricity was 362.077 MWh/yr in total electricity of 2402.572 MWh/yr. The excess electricity produced was used in hydrogen production, and hydrogen production was 3423 kg/yr. The levelized energy cost of the hybrid system was obtained as $0.561. In a rural area with geothermal resources, this new hybrid system is quite reasonable in terms of both meeting the electricity needs using renewable energy and uninterrupted use by storing excess energy and hydrogen.
