Value-based reliability evaluation of electric distribution systems

Abstract

The authors describe the evaluation of the worth or value of distribution system reliability using quantitative reliability analysis and customer interruption costs. The ability to assess reliability worth makes it possible to optimize the reliability of a system by comparing the reliability worth with the associated system investment costs. The analyses include an evaluation of the reliability of different design/operating configurations of a distribution system and the corresponding reliability worths at the customer level. The reliability of each system configuration is evaluated in terms of the system performance indices and the expected customer outage costs due to power interruptions.<>
