| 摘要: |
| 基于复杂网络理论及电力系统有功分布的实际特点，并考虑发电节点和负荷节点的有功注入，采用准稳态功率转移分布因子建立改进支路权重模型，该模型可以从支路承担有功传送的功率大小角度反映系统节点之间的连接强度。基于此，建立基于改进支路权重定义下的电力网络测度模型，该模型能够从电网传送有功以及电网拓扑结构角度综合体现系统元件复杂网络特性的多样性和差异性。算例分析结果验证了所提模型的有效性和可行性。 |

| Abstract: |
| Based on the complex network theory and the actual active power distribution of power system，the quasi-steady PTDF（Power Transfer Distribution Factor） is applied to set up an improved branch weight model，which considers the active power injection of generator nodes and load nodes and reflects the connection strength between system nodes from the view of branch power transmission. The measurement models of power grid are built based on the definition of the improved branch weight，which，from the view of active power transmission and power grid topology，reflects comprehensively the diversity and heterogeneity of system components in complex network characteristics. Results of case analysis verify the effectiveness and feasibility of the proposed model. |
