With the extensive access of multi-type energy conversion equipment in IES, the dynamic characteristics of the heat network have an increasingly significant impact on the operation of the system. The implementation of low-carbon energy transformation strategy makes carbon emission become one of the focuses of IES operation. In this regard, this paper carries out a study on the coordinated scheduling of POWER-gas-thermal IES considering thermal dynamics and carbon trading. First, the steady-state modeling of the heating network is carried out to analyze the temperature change at the outlet of the pipeline, and the time delay and the difference of virtual energy storage characteristics are studied based on the steady-state power flow analysis. To further meet the development needs of the current carbon trading market, carbon trading is considered in the operation of IES, and a coordinated scheduling model of power-gas-heat IES with the lowest comprehensive costs such as system energy consumption cost, operation cost, carbon trading cost and wind and light abandoning punishment cost is built to tap the potential of energy conservation and emission reduction from multiple links. At last, the electric power system, 17 to 10 node gas 30 nodes system and thermal system of integrated energy system as an example for the simulation analysis, the results show that considering the dynamic characteristic and carbon trading network coupled coordination scheduling more IES, energy transfer across time and space characteristics significantly, by running a significant boost IES flexible IES internal and external friendly interactive, and effectively reduce carbon emissions and achieve the comprehensive and efficient use of energy.
