In this research at frist the cogeneration system comprise the cascade steam Rankine cycle, absorption cycle and vapor compression cycle with parabolic trough solar collector as heat source are simulated from energy, exergy, economic and exergoeconomic point of view. The simulation is in this manner: at first the mass, energy and exergy conservation equation are written and the with cost balance equation in different component of system, investment cost and exergy destruction cost rate are calculated. The result in basic input mode shows that total work output, total exergy destruction and net exergy efficiency are 35.21 KW, 356.8 KW and 12.5 % respectively. The exergoeconomic results show that total cost rate is 56.86 $/hr and total exergoeconomic factor is 45.02 % that shows a good balance between initial and exergy destruction cost rates. also solar collector and steam turbine should be further considered from the exergoeconomic viewpoint since these components have the highest value of cost rate. At the end, a parametric analysis are done in order to the investigation of the effect of change steam evaporator temperature, pinch point temperature different, steam condenser temperature and generator temperature on system performance from energy, exergy and exergoeconomic point of view.
