| 摘要: |
| 海上多平台气-电互联系统的耦合元件和稳态模型与传统气-电互联系统有所不同，故而对其进行稳态建模和能量流分析。互联系统的模型不仅对气网、电网和传统气-电互联系统的耦合元件压缩机和透平发电机进行了建模，还考虑了海上多平台的特点，提出海上平台电采气耦合过程并构建模型。基于顺序潮流算法，采用适合多平台实际情况的多平衡节点能量流算法进行能量流分析。最后，以某海上多平台气-电互联系统为算例，计算结果验证了所提模型的适用性和能量流算法的有效性。 |

| Abstract: |
| The coupling elements and steady-state model of offshore multi-platform gas-electricity interconnection system are different from those of traditional gas-electricity interconnection systems, so the steady-state modeling and energy flow analysis are carried out. The interconnection system model is developed, in which not only the gas network model, power grid model and the compressor and turbine generator of traditional gas-electricity interconnection system model are included, but also considering the characteristics of offshore multi-platform, the power to gas coupling process of offshore platform is proposed and its model is built. Based on the sequential energy flow algorithm, a multi-slack bus model that is adaptive to the multi-platform environment is adopted to analyze the energy flow. Finally, an actual offshore multi-platform gas-electricity interconnected system is taken as an example to verify the applicability and effectiveness of the proposed model. |
