Exergoeconomic and Environmental Analysis and Multi-Objective Optimization of a New Regenerative Gas Turbine Combined Cycle

Combined cycle systems have an important role in power generation. In the present study, three different configurations of combined Brayton and Rankine system are studied from perspective energy, exergy, exergoeconomic environmental perspectives. Results indicate that it depends on preferences criteria each decision maker to select best configuration among proposed as final configuration. For purpose parametric analysis, effect changing various parameters such compressor pressure ratio, gas turbine inlet temperature output work, exergy efficiency, exergy-economic is studied. addition, attempt made optimize performance considering objective functions total cost rate unit produced electricity.
