A Comparison Of 3 Fundamentally Different Methods For Generating Capacity Reliability Evaluation

This paper describes the basic concepts associated with reliability evaluation of generating systems. The concepts involved in the inclusion of generating unit forced outage rates in generating capacity adequacy assessment and the evaluation of system unsupplied energy and production costs are illustrated using two reliability test systems. The basic objective of the paper is to compare three analytical methods, the load modification technique, the cumulant method and the segmentation procedure, in terms of their accuracy and computational speed in conventional generating capacity planning.
