Abstract

Abstract:

Intelligentization is the foundation of the development of the distribution network and one of the main directions of the development of the distribution network.The access of distributed power sources and diversified load are bound to have an impact on the reliability of the distribution network.The impact of distributed power sources and diversified loads on the reliability of distribution network power supply was mainly analyzed.The strategies and methods to improve rebiability of distribution automation intervention were summarized and studied.After the intervention of distribution automation,the calculation model of reliability in different modes was built and the effectiveness of the reliability calculation results was evaluated based on the analytic hierarchy process and the FMEA failure mode consequence analysis method.Finally,it elaborated on the further issues that need to be considered in the reliability calculation method of the distribution network with distributed power sources and diversified loads,and the direction of standardization for popularization and application.

Key words: distributed generation, diversified loads, distribution network reliability, distribution network automation
