异常链路分析在电力网络恢复中的应用

在大规模瘫痪状态下的电力系统的恢复过程中,网络中的一些特殊连边起到了关键作用,这是该文提出的基于异常链路分析的网络重构策略的主要思想。通过链路预测算法对网络中真实存在的连边进行异常度排名,以优先恢复异常度高的电源节点为目标,建立骨架网络恢复策略,然后根据链路的重要性进行骨架网络之外的线路的修复。这样不仅可以快速连通电源发电机,也能及时恢复重要线路,具有实际意义。

Application of Abnormal Links Analysis in Restoring Power Networks

Some special links in the power system networks play a key role under the restoration process of large area breakout. This paper proposes a network reconfiguration strategy based on the analysis of the abnormal links. By ranking the abnormalities of these real links through link prediction algorithms, we establish a Skeleton-network recovery strategy, aiming at prioritizing restoring of nodes with high abnormalities, and then recover another links according to their significance. The strategy not only can connect the power generator quickly but also restore important routes timely, showing potential significance in practice.
