Regarding the growing cost of energy, shortage of resources, and environmental issues, the importance of reducing energy consumption and optimization of related industries has been revealed more than anytime. Solar energy is one of the suitable solutions to acquire clean and cheap energy. The first step is to design the cycle using Aspen HYSYS simulator. After that exergy analysis is carried out on the proposed system. Results show that LPT2, LPT3 and HEX2 have the highest exergy destruction and should be considered for revision. Results of exergy analysis are then examined more deeply with the help of advanced exergy analysis. In this section exergy destruction is divided into four parts, endogenous/exogenous and avoidable/unavoidable to investigate the precise reason of the components’ exergy destruction. Results show that the three components which had the most exergy destruction, are the real reason behind exogenous exergy destruction of the system so by optimizing these components we can also decrease the total exergy destruction of the system too. At last by choosing the right variables and total produced work as the primary function, the optimization is done using the Aspen HYSYS optimizer and the optimized parameters are compared to the basic parameters which resulted in more power production and less exergy destruction and production cost.
