With the proposal of "dual carbon" goal

natural gas

as an important energy in the transition period of thermal power transformation

urgently needs to achieve safe and stable operation through green transformation. The application of carbon capture

utilization and storage (CCUS) technology will provide reliable technical support for the low-carbon development of gas power plants. This paper proposes a generator unit (GU) -power to gas (P2G)-CCUS system

and constructs a data-driven robust optimization (DDRO) model considering the uncertainty of wind power output. On this basis

because the existing optimization methods cannot achieve scientific cost allocation

considering the cooperative game relationship between the entities and the stability of the system operation

a cost allocation model based on the nucleolus based cooperative game (NCG) within the system is established to ensure the scientific and reasonable cost allocation. The results show that the introduction of CCUS can significantly reduce carbon emissions and gain additional profits by participating in the carbon market; DDRO model can effectively resist the interference of uncertain wind power output

enhance the security of system operation

and reduce the conservatism of traditional optimization model; NCG model can realize the reasonable allocation among GU

P2G and CCUS

so that each participant can obtain higher income than its independent operation

improving their willingness to cooperate

and thus enhancing the long-term and stability of cooperation.
