Exergy analyses and optimization of a single flash geothermal power plant combined with a trans-critical CO2 cycle using genetic algorithm and Nelder–Mead simplex method

Abstract

Highlights Designing and simulating a combined single flash geothermal cycle with a trans-critical carbon dioxide cycle in the EES software. Genetic algorithms (GA) and the Nelder–Mead simplex (NMS) method are used to optimize the proposed system to increase the system’s exergy efficiency. Examining the system’s various components’ energy destruction rates.
