The low-carbon construction of integrated energy systems is a crucial path to achieving dual carbon goals, with the power-generation side having greatest potential for emissions reduction and most direct means reduction, which current research focus. However, existing studies lack precise modeling capture devices cascaded utilization hydrogen energy. Therefore, this paper establishes power plant model based on comprehensive, flexible operational mode coupled two-stage P2G (Power-to-Gas) device, exploring “energy time-shift” characteristics system. IGDT (Information Gap Decision Theory) used discuss impact uncertainties generation results show that by promoting consumption clean utilizing high efficiency while reducing reliance fossil fuels, proposed system not only meets demands but also achieves more efficient emission laying solid foundation sustainable future. By considering uncertainties, ensures resilience adaptability under fluctuating renewable supply conditions, making significant contribution field transition.
