TL;DR: In this article, a comparative study of different geothermal power plant concepts, based on the exergy analysis for high-temperature geothermal resources, is presented, and the performance of each cycle has been discussed in terms of second-law efficiency, exergy destruction rate, and first-law efficiencies.

TL;DR: In this article, the performance of the trilateral power cycle was compared with those for the ORC (organic Rankine cycle) and the Kalina cycle, from the viewpoints of thermodynamics and thermoeconomics.

TL;DR: In this article, the performance of an ammonia-water power/cooling cogeneration cycle is investigated and optimized paying more attention on the economic point of view, and the results show that the sum of the unit cost of the cycle products obtained through thermoeconomic optimization is less than by around 18.6% and 25.9% compared to the cases when the cycle is optimized from the viewpoints of first and second laws of thermodynamics, respectively.

TL;DR: In this article, the authors compared the performance of the basic, dual-pressure and dual-fluid ORCs and the Kalina cycle for power generation from the geothermal fluid reservoir from energy, exergy and exergoeconomic viewpoints.

TL;DR: In this paper, the performance of the ORC (organic Rankine cycle) powered by geothermal water, in three different configurations, including the simple ORC, PTORC (parallel two-stage ORC) and STORC (series two stage ORC), using zeotropic working fluids is investigated from the viewpoints of the energy and exergy.
