Optimization of Integrated Energy System Scheduling Considering Stepped Carbon Emission Trading Mechanism and Electricity Heat Demand Response

This paper established an economic dispatching model of integrated energy system. In this model, carbon trading mechanism modeling and electricity heat demand response model are added to the traditional integrated energy system. Firstly, the traditional demand response of electricity price is converted into the influence coefficient of electricity price. Secondly, the incentive demand response of electricity and heat energy is considered. Finally, this paper proposed a carbon trading strategy of integrated energy system. This paper took the parameters of the integrated energy system in a park as example data, and set up two scenarios for example simulation. Through the simulation analysis of the example, it can be seen that the carbon trading model and the electrothermal demand response model mentioned in this paper can reduce the carbon emission cost of the system, reduce the total operation cost of the comprehensive energy system, and realize the improvement of the two indexes of high economy and low carbon emission.
