摘要

Given the complexity of power grids,the failure of any component may cause large-scale economic losses.Consequently,the quick recovery of power grids after disasters has become a new research direction.Considering the severity of power grid disasters,an improved power grid resilience measure and its corres-ponding importance measures are proposed.The recovery priority of failed components after a disaster is determined according to the influence of the failed components on the power grid resilience.Finally,based on the data from the 2019 Power Yearbook of each city in Shandong Province,China,the power grid resilience after a disaster is analyzed for two situations,namely,partial components failure and failure of all components.Result shows that the recovery priorities of components with different importance mea-sures vary.The resilience evaluations under different repair conditions prove the feasibility of the proposed method.
