Abstract
Recursive algorithms and approximations using continuous distributions are the two basic techniques for reliability calculations of generation systems. Within assumptions common to both methodologies, recursive without using any round-off is exact method but it is computationally less efficient than the continuous distribution methods like Gram-Charlier expansions. A significant effort has been spent in the recent past to improve the accuracy of continuous distribution methods. This thesis presents a continuous distribution method for calculating the reliability indices of a system connected to one or more assisting systems. A multi-parameter distribution consisting of a combination of gamma distributions is used for representing the area generation system models. A cluster based load model is used for incorporating the hourly load variation and to capture the correlation between area loads. The concept of equivalent generators to represent the assisting systems is used for incorporating the interconnection effects. Several studies are reported using IEEE-RTS and EPRI System E. The indices of LOLE, EUE and LOLF are obtained and are compared with those of the recursive method for accuracy and efficiency.
