This study aims to improve the emergency preparedness and emergency decision-making ability of power grid enterprises.Firstly,based on the scenario construction theory and disaster system theory,42 accident cases of power grid enterprises responding to typhoon disasters in recent 15 years were analyzed,and the structured hierarchical model of"event-scenario-scene-task-capability"and its index system of typhoon disaster of power grid enterprises were constructed.According to the characteristics of each index(fuzzy,judgment and numerical),the corresponding similarity calculation methods were matched.G1 method and entropy method were used to determine the subjective and objective weights to obtain the comprehensive weights,so as to calculate the overall similarity and the early-warning and response two-stage similarity.Finally,a decision-making of a power grid enterprise in a certain city in Typhoon"Meranti"was taken as the target case.The results show that,compared with the traditional model,the structured hierarchical model of"event-scenario-scene-task-capability"can realize the phased retrieval,which can better meet the decision-making needs of the early warning and response stage in the emergency process.
