Laddered Carbon Trading-based Scheduling for Integrated Electricity-Gas Systems with Hydrogen Injection Considering Hydrogen Mixed Gas Turbine

Hydrogen is recognized as a clean and appealing energy carrier that offers significant flexibility enhancements to power systems. This paper proposes a laddered carbon trading-based energy scheduling model for integrated electricity-gas system (IEGS) with hydrogen injection considering the combustion properties of hydrogen mixed gas turbine (HMGT). The power-to-hydrogen, carbon capture, utilization and storage facility and laddered carbon trading are considered to reduce the carbon emission. Then, a simplified HMGT combustion model based on the system thermodynamics is developed. A quasi-steady-state operation model for gas system with hydrogen injection is also introduced and solved by a convex relaxation method. Case studies illustrate the effectiveness of the proposed model.
