Overview

Computational modeling reveals optimized solar-assisted cogeneration boosts water output and exergetic efficiency while reducing costs, indicating a sustainable pathway for arid regional energy grids.

Key Points

  • To design and optimize an integrated solar-assisted gas turbine and hybrid desalination cogeneration system tailored for power and freshwater generation in arid regions.
  • Modeled a combined gas turbine and parabolic trough collector solar field integrated with hybrid multi-effect distillation and reverse osmosis units using Thermoflex.
  • Performed a 4E analysis evaluating energy, exergy, exergoeconomic, and exergoenvironmental performance criteria.
  • Implemented the Non-dominated Sorting Genetic Algorithm III (NSGA-III) in MATLAB to maximize exergetic efficiency while minimizing total costs and emissions.
  • System optimization increased exergetic efficiency from 47.31% to 60.12% and decreased total operating costs by 6.58%.
  • Freshwater output expanded from 120.10 kg/s to 142.87 kg/s, representing an 18.96% improvement in production capacity.
  • Total environmental emissions decreased by 4.27% under the optimal operating configuration.
