Abstract: To address the challenges of high carbon emissions, significant costs, and complex energy management in large offshore platforms, this paper aims to establish an Integrated Energy System (IES) model for comprehensive management of gas, hydrogen, electricity, heat, and cooling energy. The objective is to decrease carbon emissions while minimizing costs. This paper integrates a stepped carbon trading mechanism to enhance the IES model. The refined model, which includes the stepped carbon trading mechanism, is evaluated across three distinct scenarios. Results indicate that the stepped carbon trading mechanism reduces carbon emissions by 44.7 tons compared to the traditional carbon trading mechanism and lowers costs by approximately 18.2 %. This demonstrates that the introduction of stepped carbon trading aids in both carbon emission reduction and cost control for offshore platform IES. Additionally, the time-scale scheduling model reveals changes in the operational outputs of cogeneration units, refrigeration units, and boiler units before and after optimization. This underscores the importance of effective energy management models for the synergistic operation of gas, hydrogen, electricity, heat, and cooling energy flows, significantly contributing to carbon emission reduction and cost control in offshore IES. The study highlights the critical role of advanced energy management strategies in enhancing the sustainability and economic efficiency of energy systems in offshore platforms.
