In the context of dual carbon

in order to realize the low-carbon economic operation of the integrated energy system

an optimal dispatching model of integrated energy system considering generalized electric heating demand response and stepped carbon trading mechanism is proposed. The organic Rankine cycle is introduced into the integrated energy system for waste heat power generation to realize the thermal and electrolytic coupling of cogeneration

so that the output of cogeneration is more flexible. The traditional demand side flexible response is introduced on the load side to cooperate with waste heat power generation

and a generalized electric heating demand response is established to further improve the low-carbon and economical efficiency of the system. A stepped carbon trading mechanism is introduced to further restrict the carbon emissions of the system. The results show that considering the generalized electric heating demand response and the stepped carbon trading mechanism can effectively reduce the carbon emissions of the system and improve the economics of the system.
