Abstract: The growing demand for energy encourages the use of organic Rankine cycles powered by renewable energies. This work introduces the novel renewable system combining a high performance concentrated photovoltaic thermal and a trilateral organic Rankine cycle for power generation. The high performance concentrated photovoltaic thermal system is sized to meet the heat requirements of a trilateral organic Rankine cycle at high evaporation temperatures of the working organic fluid. Mathematical models are developed for different components of the combined system. The differences between current and previous work models did not exceed 3%. The results showed that the electric power generated by the combined system varied between 70 and 273 kW and the overall efficiency ranged from 29 to 38.55%. Effect of some parameters such as the incidence angle, the aperture area and the condensing temperature of the working organic fluid on the system efficiency are investigated. The results demonstrated that production performance decreased as the incidence angle and the condensing temperature of the working fluid increased. The results also showed that the levelized cost of electricity of the combined system ranged from 0.047 to 0.099U$/kWh. The overall results highlighted that the production performance of the renewable system was very high compared to other solar technologies presented in the literature review.
