| 摘要: |
| 针对网架重构过程中，待恢复节点的拓扑重要性随网络逐步恢复而发生变化的特点，提出一种节点拓扑重要性的动态评价指标——动态节点重要度。在重构决策中，基于当前系统恢复状态，通过将已恢复节点合并成一个等效电源点，构造包含及不包含等效电源点的2个待恢复网络，综合考虑待评价节点的收缩对2个网络的影响，计算出待评价节点的动态节点重要度指标。在此基础上，将所定义的动态节点重要度指标用于网架重构中机组恢复的路径优化问题。新英格兰10机39节点系统算例验证了所提动态节点重要度评价指标及路径优化方法的有效性。 |

| Abstract: |
| Since the topological importance of a node to be restored changes during the network reconfiguration, a dynamic index of nodal importance is proposed to dynamically assess the topological importance of node. During the decision-making of network reconfiguration, the restored nodes are merged into an equivalent power source based on the present restoration state of system. Two networks to be restored, with and without the equivalent power source, are thus formed, the effect of node contraction for a node to be assessed on these two networks is comprehensively evaluated and the dynamic importance of that node is thus calculated. The proposed index is applied to the path optimization of unit restoration during the decision-making of network reconfiguration. New England 10-unit 39-bus system is taken as an example to verify the effectiveness of the proposed index and path optimization method. |
