Review on Typhoon Disaster Chain Early Warning and Response in Distribution Network

The disaster chain triggered by typhoon has long duration, wide impact range, and complex disaster mechanism. These disaster chain has caused significant losses to distribution network. This paper reviews current research progress and issues that need to be addressed from three perspectives: outage risk analysis, outage prediction, and repair path optimization for distribution network. Firstly, the complex disaster mechanism faced by distribution network under typhoon disaster chain is analyzed. It emphasizes the necessity of studying the outage risk analysis by taking disaster chains as a whole. Secondly, it elaborates on the problems of data imbalance and poor interpret ability in outage forecast research. The physical-data fusion modeling's feasibility will be explored to enhance distribution network's early warning capability. Finally, the interaction mechanism among typhoon disaster chain, transportation and distribution network are discussed. By discussing emergency repair path optimization method, the distribution network's disaster response ability is enhanced.
