Abstract: Targeting the problem of strong electricity carbon coupling existing in traditional carbon capture power plants,the paper proposes a collaborative operation method of carbon capture-power-to-gas（P2G）based on renewable energy. Firstly,the output of carbon capture power plant is modeled according to the different sources of energy supply of carbon capture equipment. Secondly,typical source-load scenarios are generated considering the uncertainty and correlation of wind ＆ PV and load. Finally,six operation modes are classified according to the different carbon capture-P2G collaborative operation modes,and the system is optimally scheduled with the objective of minimizing the overall operating cost of the system. The algorithm analysis shows that the proposed operation method achieves decoupling between the carbon capture and carbon capture plant capacity and improves the system economy.
