Abstract: In order to give full play to the interaction potential of both sides of supply and demand under the background of low-carbon economy,a bi-level low-carbon economy scheduling model of electricity-gas-heat integrated energy system（EGH-IES） considering integrated demand response（IDR） and carbon trading mechanism is proposed.Firstly,an IDR model considering the self-characteristics,coupling characteristics and load rebound effect of multi-energy loads and a comprehensive benefit model of weighing economic benefit,response mode and energy preference of users are proposed.Based on this,a bi-level optimal scheduling model is established. The upper model is the EGH-IES low-carbon economic optimal scheduling including the carbon trading mechanism based on rewards and punishments,and the lower model is IDR strategy. Then, the bi-level model is converted into a mixed integer linear programming problem by Karush-Kuhn-Tucker（KKT） condition, duality theorem and linearization method. Finally, the example analysis shows that considering carbon trading mechanism and multiple load characteristics can promote the joint optimization of supply and demand sides,and give full play to the low carbon economy of EGH-IES.
