Abstract

With the integrated energy system (IES) that considers multi-energy complementarity and energy cascade utilization becoming an important trend in energy innovation, aiming at the current IES carbon emission reduction task and safe and stable operation requirements, accurately solving the maximum carbon emission capacity under the safe operation of IES can warn the working state of the system and provide references for carbon emission reduction tasks. Firstly, the steady-state IES energy flow and carbon flow model of electric-gas coupling is established. On this basis, the calculation model of IES maximum carbon emission capacity was established. Then, the mathematical model of IES carbon emission capacity curve is established. Finally, a numerical example is given to verify the effectiveness of the proposed model.
