Abstract: The reliability of distribution network is key factor for the power supply reliability, and the reliability evaluation method for distribution network has also been studied widely. According to different conditions, the existing reliability evaluation method for distribution network is classified in this paper. Different reliability evaluation method is introduced, and the advantages, disadvantages and the applicability of each method are also researched. By combining the shortcomings in reliability evaluation for distribution network and the development direction of distribution network, the problems of reliability evaluation that need to be researched in the future intelligent distribution network are prospected.
