Thermo-economic and sensitivity analysis of a central tower hybrid Brayton solar power plant

Abstract: A hybrid central tower thermo-solar plant working with a gas turbine is simulated by means of an in-house developed model and software. The model considers the integration of all plant subsystems. The calculation of the heliostat solar field efficiency includes the main losses factors as blocking, shadowing, attenuation, interception, and cosine effect. The simulation considers a Brayton cycle for the power unit with irreversibilities in the compressor and turbine, and pressure drops in the heat absorption and… Show more

“…When the organic working fluid of ORC is R123, the optimized cycle performance of power output and energy efficiency are 46 MW and 52.27%, respectively. Merchán et al (2021) analyzed a tower hybrid GT solar system about its thermo-economic performance. It found out that when the turbine inlet temperature rises from 1,300 to 1,500 K, the levelized cost of electricity (LCOE) decreases from 188US$/MWh to 150US$/MWh.…”
