Abstract
To effectively improve the absorption capacity of the integrated energy system (IES) to clean energy, reduce the carbon dioxide emissions of the system, and improve the economic benefits of the system, this paper constructs a comprehensive energy system model that includes both electricity to hydrogen and hydrogen to gas and introduces the carbon dioxide trading mechanism, the green certificate trading mechanism and the response mechanism to the load demand. Different scenarios are set for example analysis and the model is solved using Matlab software's CPLEX solver. The results show that the operation strategy of the IES considering demand response under the carbon dioxide–green certificate joint trading mechanism performs best, reducing the total cost of the system by 65.8% and the carbon dioxide emissions by 23.1%, which can provide a strong reference and guidance for the low carbon dioxide economy operation of the IES.
