“…While the highest exergy efficiency of the system was found as 28%, the maximum electricity production was calculated as 550 kW. Colakoglu and Durmayaz [22] evaluated the energy and exergy analysis of a triple combined cycle including the solar tower. The energy and exergy efficiency of the proposed system were found to be 51.99% and 37.99%, respectively.…”

Nowadays, energy is obtained from both fossil fuels and renewable energy sources. The use of fossil fuels causes climate change and global warming. The use of renewable energy systems ensures the reduction of greenhouse gas emissions and, as a result, the reduction of global warming. In this study, a solarbased electricity generation facility, which is one of the renewable energy sources, is discussed. The power generation potential of the solar system with integrated Rankine cycle under the changing climatic conditions of Iskenderun, which is a region with high solar energy potential, is investigated by thermodynamic analysis. A solar power tower was selected as the solar energy system in the facility. In the facility, electrical energy is obtained by sending the heat energy obtained from the solar power tower to the steam Rankine cycle. Energy and exergy analysis were performed to find the performance of the facility and the main sources of exergy destruction. As a result of the thermodynamic analysis, the net power obtained from the system increased with the increase of the input heat. During the day, 495.3 MWh/day of heat entered the system and 202.3 MWh/day of net power was obtained from this heat. The highest exergy destruction in the system occurred at 12:00. The highest exergy destruction occurred in the receiver at this hour and was calculated as 13.83 MW. The daily average energy and exergy efficiencies of the system were found to be 40.8% and 66.08%, respectively.
