In the context of the dual-carbon strategy,the integrated energy system has become the main way to explore the low-carbon and efficient utilization of renewable energy and multi-energy coupling.In order to take into account the sta-bility and economic benefits of the integrated energy system in low-carbon optimization,this paper proposes a distributed robust low-carbon optimization strategy for integrated energy system with carbon capture,utilization,and stor-age-electricity-to-gas coordinated operation.Firstly,the detailed modeling of the power-to-gas process is carried out to study the various benefits of hydrogen energy.A CHP-CCUS-P2G coupling model is established,and the stepped carbon trading mechanism is introduced.A CHP-CCUS-P2G low-carbon economic dispatch method based on stepped carbon trading mechanism is proposed.Secondly,the uncertainty of wind and solar power output is taken into account,a da-ta-driven min-max-min two-stage robust scheduling model is constructed on the basis of the historical data available in the scheduling system,and the 1-norm and ∞-norm are used to constrain the scene probability distribution fuzzy set.Finally,the model is iteratively solved based on the column constraint generation algorithm.The simulation results show that the above model improves the wind and light consumption rate and economy of IES,and reduces the system emissions.
