چکیده

Due to the necessity of using highly efficient power generation systems to reduce fuel consumption and air pollution, the integration of different energy systems is promising modification to achieve higher efficiency. in this paper, the integration of an internal reforming solid oxide fuel cell (irsofc)gas turbine (gt)organic rankine cycle (orc) system has been proposed. in this regard, thermodynamic modeling and simulation of the proposed system have been done to evaluate the performance of the integrated system. also, exergetic, exergoeconomic and advanced exergetic analysis has been performed for the proposed system. the analysis of the integrated system has been carried out by using matlab code. verification of thermodynamic simulation has been performed with high accuracy. results of thermodynamic simulation show that the net power and overall cycle efficiency of the proposed cycle are increased by 1.1 mw and 7.7 % respectively rather initial sofcgt combination. the exergy analysis indicated that exergy efficiency is 40.95%, for the proposed system and 37.3% for the initial base case. as a result, the exergy destruction, exergoeconomic factor, cost rate per exergy unit of product and fuel, and cost rate associated with the exergy destruction for each component are calculated and evaluated. also, endogenous/exogenous and avoidable/unavoidable parts of exergy destruction, exergy destruction costs, and capital costs have been determined and compared.
