Probability Distribution Development in Distribution System Reliability Evaluation

Abstract

Conventional distribution system reliability evaluation is focused on the determination of average loadpoint andsystem reliability indices. The actual annual reliability performance of a distribution system is, however, a random variable with an associated probability distribution. This paper illustrates the development of the average reliability indices and their probability distributions for a small test system. The probability distribution can provide useful information on customer impacts and considerations in a deregulated power market.
