Abstract

This paper describes a new method for rapidly detecting modal deterioration in large interconnected multi- modal power systems. Any "sudden detrimental change" of an individual mode is detected using strategies derived from optimal detection theory. A statistical characterisation is used to establish reliable thresholds for detection of individual mode changes.

Citation countsare sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
