  7. Abstract:
  8. Combined geothermal heat pump and solar collector system is a kind of load supply system for dwellings and greenhouses that operates by relying on renewable energies. The advantage of this system over conventional systems is lower power consumption. The aim of this study is to optimize the hybrid system so that in addition to reducing energy consumption and exergy destroied of the system, economically be minimized. In fact, in this study, we are dealing with an issue that should be optimize from different aspects. firstly, thermodynamic modeling for vertical ground source heat pump is done and then by considering 11 decision variables, the system is optimized by using single-objective and multi-objective optimization. One of the objective functions is products cost and the other one is exergy destruction of the system. The results show that using multi-objective optimization methods in power systems provide the ability to predict and improving the results of different decisions, also enabling the analysis of conflicting goals with each other. For modeling and optimization, MATLAB is used and thermodynamic and economic analysis of the optimized system was carried out by using decision variables of the optimization process and finally the sensitivity analysis of the system to change various parameters has been studied
