Reliability indexes for power systems. Final report, March 1981
Three main objectives were accomplished during this project. The first objective was to review the traditional treatment of power system reliability indexes. A qualitative analysis of both generation and transmission indexes is presented along with a detailed examination of the analytic and computational algorithms which have been developed. Several algorithms are given that are computationally more efficient than those commonly given in the literature. The second objective was to advance the state of the art by developing a unified probability framework for the definition of power system reliability indexes. The key idea in this approach is the notion of a reliability indicator as an observable characteristic central to describing the reliability of a system. Using this concept, reliability indexes are defined as parameters of probability laws of reliability indicators, thereby providing new insights for the understanding and computation of reliability indexes. The final objective was to evaluate all of the reliability indexes in terms of their usefulness to utility planners and consumers and to determine the characteristics required for quantification of the worth of reliability. Based on interviews with both utility planners and regulators, a ranking of reliability indexes was developed.
