Modeling and Optimization of an Integrated Energy System for Combined Cooling, Heating, and Power

Energy crisis and environmental pollution are two important issues related to the development of human society, which are of great concern to countries around the world. In order to accelerate the realization of the dual-carbon goal, improve energy utilization efficiency and reduce carbon emissions, the key energy supply equipment Cold, Heat and Power (CCHP) system is selected to construct an integrated energy system model. The changes in the overall operation mode and efficiency of the park after the introduction of this equipment are investigated using the improved Non-dominated Sorting Genetic Algorithm-II (NSGA-II). The results show that the CCHP equipment can realize the multi-energy complementarity and energy gradient utilization of the energy upper side equipment through its strong coupling characteristics; it can be seen that the introduction of the CCHP can greatly improve the operation efficiency of the integrated energy system, reduce the operation cost while relatively controlling the release of carbon emissions, and improve the overall efficiency of the systemt.
