The system must have sufficient reserve capacity to permit it to operate at an adequate level of reliability. The evaluation of generating capacity reliability can be considered to take two basic forms which can be designated as the static and the spinning reserve requirements. This thesis investigates the application of the frequency and duration concept to the static reserve problems. Equations for fast computation of the cumulative availability and frequency of capacity outage states are developed. Relationships are also developed for the reliability evaluation of a system connected to one or more systems. A general computer programme for the reliability evaluation of single and two area problems has been developed. The concepts developed in this programme are illustrated by application to the Saskatchewan and Manitoba Systems.Thesis
