The frequent occurrence of extreme ice and snow disasters can lead to blackout in distribution network and cause heavy loss in economy. In order to enhance the capability of distribution network to deal with natural disasters

firstly

the resilience restoration capability evaluation indices are proposed under the idea of resilient distribution network. The indices mainly include the catastrophe severity evaluation index

the emergency restoration capability evaluation index and the overall system restoration capability evaluation index. Secondly

from the perspective of planning and operation

the resilience enhancement measures are presented

and the proposed resilience restoration capability indices are adopted to reflect the effect before and after the promotion. Finally

the real 65-node distribution network and the modified PG&E69-node standard test system verify that the proposed resilience restoration capability indices can be adopted to reasonably evaluate the operation status of the distribution network after the disaster

and effectively evaluate the application effect of the enhancing measures.
