基于可再生能源的碳捕集-电转气协同运行方法

针对传统碳捕集电厂存在的强电碳耦合问题，提出基于可再生能源的碳捕集-电转气协同运行方法。首先，按照碳捕集设备供能来源的不同对各方式下碳捕集电厂的出力进行建模；其次，考虑风光和负荷的不确定性和相关性生成典型源荷场景；最后，根据碳捕集和电转气协同运行方式的不同划分6种运行模式，并以系统综合运行成本最小为目标对系统进行优化调度。算例分析表明，所提运行方法实现了碳捕集与碳捕集电厂产能之间解耦并提升了系统经济性。

Collaborative Operation Method of Carbon Capture-P2G Based on Renewable Energy

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.
