In the present research, a dual flash cycle is used to use the waste energy of a geothermal cycle. In order to better recover the energy an ORC is employed to uses the waste energy of the dual flash cycle to generate power. Energy, exergy and exergoeconomic equations for each component of the system are obtained. The results show that the net power of the geothermal cycle, dual flash cycle and ORC are 159.37 kW, 333.5 kW and 52.2 kW, respectively. Moreover The condensers and the heat exchangers have the most exergy destruction rates. Furthermore, the condensers have the lowest exergoeconomic factor compared to other system components. The total exrgoeconomic factor of the system is 34.96 %. The parametric analysis indicates that by increasing the input pressure of the geothermal turbine and the output pressure of the first double flash cycle turbine, the total power of the system increases and the total costs of the system decrease. However, increasing the output pressure of the geothermal turbine reduces the overall power and costs of the cycle. Moreover, With the increase of the maximum pressure of the double flash cycle, the total power of the system first increases and then decreases, and the total costs show an inverse trend with the production power.
