Case study of distribution network reliability analysis based on probabilistic method

Abstract

One of the most important purposes of reliability assessment of distribution network is reducing interruptions for customer service. In this paper reliability of large distribution network of a city is calculated based on probabilistic method. After analysis the reliability indexes, some solutions are introduced to improve weak zones. By comparing results and using simple approaches we can improve reliability of system without any significant additional cost and it is clearly showed that the benefits of these assessments in design or development stage.

Reliability Evaluation of Direct Current Distribution System for Intelligent Buildings Based on Big Data Analysis

“…The domestic research on DC distribution system has just started. Most of the existing studies focus on topological design, key device control, and energy management, with inadequate research into system reliability [11][12][13][14]. By the minimum cut-set method, Shi et al [15] qualitatively analyzed the reliability of DC distribution system, and proved through experiments that equipment-level redundancy design brings a better DC distribution reliability than component-level redundancy design.…”
