Abstract
Cogeneration combined heat and power cycle components are continually optimized using new methods and solutions. Due to the interconnection of two different power generation cycles, the design of the cogeneration cycle is extremely complex and any changes in the structure directly affect the power, efficiency, costs, and other variables. To address this issue, a new arrangement of the cogeneration combined heat and power cycle is presented in this study, as well as a suitable fit function for exergy analysis and evolutionary algorithms used for model optimization. Several objectives are considered when optimizing, such as reducing costs, increasing profitability, etc. Optimization algorithms increased energy efficiency by 2.7% and exergy efficiency by 8.6%, indicating substantial long-term energy savings. A significant improvement was made in all desired parameters as well. Therefore, we can conclude that the upgraded algorithm considered in this study is effective in designing power generation cycles due to the particular importance of optimal design in power generation cycles.
