| 摘要: |
| 为了充分利用可再生能源，增强电力系统各区域间的互联协调能力，提出了一种基于目标级联分析(ATC)法的输电网结构优化模型。首先，利用母线撕裂法将电力系统解耦为多区域互联系统；其次，建立含可再生能源发电的输电网结构优化模型，在此基础上，进行多区域互联电力系统的统一分析和决策；再次，采用ATC法将模型分解为主问题和子问题进行并行计算，实现源网荷协同的输电网结构优化。最后，通过对IEEE 14节点及IEEE 118节点系统的测试分析，验证了所提模型可有效协调互联电网的运行，提高电力系统运行的经济性。 |

| Abstract: |
| To make full use of renewable energy and enhance the interconnection and coordination among different regions of power system, an optimal transmission switching model based on analytical target cascading(ATC) method is proposed. Firstly, the power system is decoupled into a multi-area interconnected system by using the bus tearing method. Secondly, an optimal transmission switching for transmission with renewable power sources is established, based on which the unified analysis and decision-making of multi-area interconnected power system are carried out. Thirdly, ATC method is used to decompose the model into main problem and subproblem for parallel calculation to realize the optimal transmission switching with the source-network-load coordination. Finally, through the test and analysis of IEEE 14-bus and IEEE 118-bus systems, it is verified that the proposed method can effectively coordinate the operation of interconnected power grid, and improve the economy of power system operation. |
