Abstract: Incorporating renewable energy and carbon trading mechanisms within the optimization methods could enhance both the environmental and economic benefits of energy systems. A tri-generation system powered by solar and wind energy is introduced, utilizing solar photovoltaics, wind turbines, and a solar cooling/heating subsystem to attain net-zero carbon emissions via renewable power and carbon trading mechanisms. An improved multi-objective algorithm optimizes the configurations of the energy system across different scenarios. The optimization results demonstrate that the integration of wind turbines, ideally with capacities near 20 MW, lessens the dependence on external power sources and decreases annual expenditure relative to systems relying solely on photovoltaic. Meanwhile, water-cooled chillers are capable of addressing over 88% of the cooling demand, with capacity exceeding 11 MW. Sensitivity analysis highlights that increasing power grid coverage and microgrid penetration rates decrease total costs, while higher building demands reduce economic performance. A new operating mode of net-zero carbon energy systems is provided in the present study.
