Abstract：Existing distribution system reliability assessment methods analyze the reliability of different voltage levels independently.Based on the coordination of multi-level network in dealing with failure,a cooperative assessment method to calculate the high-medium voltage distribution system reliability is presented.First of all,a three-level model of the distribution network applied in cooperative assessment is carried out through analyzing the structure and operating characteristics of the multi-level network.And the cooperative assessment model which can be used to evaluate the reliability of the multi-level network is constructed based on coordination between different levels.Secondly,according to the typical connection modes in the high voltage distribution system and the multi-linked structure in the medium voltage distribution network,a cooperative assessment method of high-medium voltage level distribution network failure effect,comprising the progressive failure effect analysis model for the high voltage distribution network and the fault restoration model for the multi-linked network,is constructed.Finally,combined with the analytical method,the process of reliability assessment based on cooperative analysis of multi-level network is proposed.Results of study case verify the effectiveness of the proposed method.
