Power System Security Taxonomy Introducing Two New Approaches

摘要

This paper has three unique contributions: the proposal of a new security taxonomy not previously seen in the literature; the presentation of a novel and successful approach (see Section V-A) to solve an important problem encompassing two conflicting security objectives, using an efficient multi-objective Pareto optimization technique; and the proposal and application (see Section V-B) of two original and very powerful probabilistic security indexes (apparent stability index and probability of instability), which render a sound solution to the consideration of uncertainties in dynamic security problems. All results are obtained based on a detailed representation of the system dynamic behavior.
