Abstract

Identification of power system modal oscillation damping in frequency has become more feasible through angle measurements and communication systems. Frequency domain estimation provides reasonable estimates of these parameters if given very long estimates and the modes are well separated. This paper shows how the estimation is improved if the modes are decoupled as part of the estimation process. The results show good performance compare to a key previous method.

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.
