Abstract :
The objective of this paper is to present an improved computational method for the overall reliability assessment of autonomous power systems that may or may not contain HVDC interconnection links. This is a hybrid method based on a Monte-Carlo simulation sequential approach which incorporates an analytical approach for the reliability modeling of the HVDC transmission links. The developed models and techniques have been implemented into a computer program that can be used to simulate the operational practices and characteristics of the overall power system under study efficiently and realistically. A set of reliability indices are calculated for each load-point of interest and the entire power system while a set of additional indices is calculated for quantifying the reliability performance of the interconnection links under the specified operating requirements. The analysis of a practical power system is also included for a number of studies representing its various operating and design characteristics
