Abstract
The frequency and duration approach is a practical method for the adequacy evaluation of generation system configurations. The primary indices of interest are the cumulative probability and frequency of a load loss situation. This technique utilizes both the event probabilities and transition rates and therefore the calculated indices are sensitive to all of these values.
In this thesis, parallel connection, series connection, margin convolution and generation and line
complements are presented as operations. A symbolic language is created to provide a notational representation of the system configuration. This thesis formulates incremental parameter and m-step boundary algorithms to derive recursive expressions for these operations.
The concept of subunits is developed in this thesis to provide a sequential procedure for the study of
looped configurations. Each system is conditioned into either a positive or negative subassisting unit. The routing of assistance is then described in terms of the subassisting units and operations to calculate the system indices for each configuration condition. This thesis also presents a method for including load correlation between interconnected systems. Several examples based on the IEEE Reliability Test System
are used to illustrate the basic concepts. The proposed Western Canada Grid is utilized to illustrate the application of the concepts developed in this thesis in a practical system context.
