Low-carbon energy sources, such as nuclear, solar, and wind, are recognized as solutions to the challenges of global warming and sustainable development. The integration of nuclear reactors and renewable energy systems into energy hubs can provide a more economical and reliable carbon-free energy supply. In this research, a techno-economic assessment of an energy hub that included a Micro Modular Reactor (MMR) and renewables is implemented in the GAMS software. The feasibility of a continuous energy supply for electrical, heating, and cooling demands is investigated in two seasons: summer and winter. Additionally, a demand response program is implemented to shift consumption loads to off-peak hours for all demands. Electrical and heat storage systems are also included in the energy hub to balance the mismatch between production and consumption over a 24-hour period. Uncertainties in renewables production and electrical, heating, and cooling loads are considered by generating 1000 stochastic scenarios using the Monte Carlo method. To manage the computational cost, the generated scenarios are reduced to the 10 most probable representatives. According to the results, integration of the MMR with a renewables-included energy hub could decrease the dependency on the grid, as well as lower operation costs, and decrease overall carbon emissions for meeting the electrical loads. Using cogeneration in both the MMR and gas turbines enables the energy hub to achieve cost savings for the production of thermal energy while avoiding excess carbon emissions. Furthermore, in summer, the absorption chiller utilizes cogenerated thermal energy to meet a part of the cooling load (Trigeneration), thereby reducing the electrical load required for cooling.
