Abstract

There is a need for improved methods in conducting reliability studies of electric power systems. This is motivated by NERC TPL-001-4 for analyzing N-1-1 contingency events. In this paper a new reliability analysis technique is developed. Referred to as a Risk-Based Reliability Method (RBRM), it is applied to a 68-bus, 16-machine IEEE benchmark to evaluate system reliability under N-1-1 analysis. Factors include the transmission line age, load flow under normal conditions and load flow under post-first-disturbance conditions. Results are also included where reliability factors are modified in order to improve the ability to identify and rank the most severe and highly probable contingencies.
