In order to estimate and evaluate the blackout consequence in distribution network, a comprehensive evaluation index system including seven indexes was built, in which the blackouts loss for both users and power companies are fully considered. A comprehensive evaluation model based on AHP and improved grey clustering decision model was provided to evaluate the blackout consequence of different fault objects in distribution network. The improved GCDM model which can overcome the limitations of traditional whiten function, clustered different evaluation indexes and improved utilization of information and evaluation result. Finally, taking a distribution network as numerical example, AHP and improved GCDM model was implemented to evaluate and analyze the blackout consequences of different objects in distribution network. The results screen the differences in blackout consequence degree of fault objects effectively, indicating that this evaluation model is feasible and evaluation result can be referenced for power companies.
