Abstract
This paper presents a novel approach to the monitoring of interarea oscillation frequency and damping using multivariate analysis techniques. A two-step method is presented 1) independent component analysis for the detection of interarea modes and estimation of their frequencies and 2) random decrement for the estimation of mode damping. The method is applied to real measurements taken in Finland within the Nordic Power System to estimate the critical interarea mode frequency and damping in the system.
