Abstract
The problem of uncertainty associated with power system reliability evaluation has been given considerable interest over the past decade. Probabilistic methods for evaluating the impact of uncertainty in the system parameters on the computed reliability indices have been developed and applied to hypothetical systems. These methods are based on the discrete distribution of the system capacity outages and can be time consuming when applied to large power systems.
This thesis treats some of the uncertainties associated with generating capacity reliability evaluation of single and two interconnected systems. The thesis examines the accuracy of the continuous representation model of the system capacity outages recently used in generating capacity reliability studies. Practical techniques to including uncertainty concepts in generating capacity reliability evaluation are developed and applied to selected power systems. The thesis also presents a simple and efficient method for developing an equivalent reliability model for two groups of parallel elements connected in series. The method presented permits the incorporation of uncertainty associated with this type of configuration. A number of studies have been conducted to illustrate the concepts, methods, and models.
