Distributional Variation Of Distribution System Reliability Indices

Reliability analyses are mainly concerned with the mean values of reliability measures, however, the distributional variation about the mean is becoming increasingly important as a supplemental measure. This paper presents the results of a series of simulations studying the distributional variation associated with indices for simple distribution systems. Distributions for the Load Point Failure Rate, Load Point Outage Duration, Load Point Annual Interruption Time, SAIDI, SAIFI, and CAIDI are presented and discussed.
