A parametric investigation of a novel ammonia water mixture power generation system is performed in this study. The overall performance and feasibility of the system of the proposed system are assessed from thermoeconomic, conventional exergy and advanced exergy perspectives. For better heat recovery in the existing medium-temperature heat recovery Kalina system, auxiliary solar heater is considered in the proposed design to improve the overall performance in terms of energy and exergy. The system performance parameters investigated include cycle efficiency, net output, total product cost rate, exergoeconomic factor and total exergy destruction rate. The simulation of the energy and exergy analysis was performed using Python coding. In this respect, the parametric investigation revealed that the cycle efficiency, net output, total product cost rate, exergoeconomic factor and total exergy destruction rate of the system at optimized conditions are 15.5%, 280 kW, 136 $/GJ, 66% and 120 kW, respectively. The irreversibilities of each component and overall system were evaluated and it was found that the turbine accounts for the highest exergy destruction among all components, contributing nearly 13% of the total exergy destruction of the system. Advanced exergy analysis was also performed that involved characterizing the exergy destruction as endogenous, exogenous, avoidable, and unavoidable, leading to specific recommendations for improving the performance of the system. Conventional exergy analysis suggests that the turbine, HE4, and separator are the components typically identified for improvement. The advanced exergy analysis in this study, however, indicated that the separator should be the primary focused for performance improvement, followed by the HE4 and turbine.
