This paper extends the method of Frequency Domain Decomposition (FDD) towards real-
time analysis of ambient PMU measurements in power systems for the purpose of oscillation …

Over roughly the past two decades, an architecture has evolved for using wide area
measurement systems to monitor power-system oscillatory dynamics. This includes, but is …

Wide-area synchrophasor ambient measurements provide a valuable data source for real-
time oscillation mode monitoring and analysis. This paper introduces a novel method for …

A method of estimating the electromechanical modes and mode shapes from multiple
synchrophasors is presented in this paper. The approach is based upon identifying the …

Linear-system formulations are often used to describe power-system small-signal
electromechanical dynamic properties. Over the past two decades, many techniques have …

Previously, variations of the Yule-Walker techniques have been applied successfully to give
point estimates of electromechanical modes of a power system based on measured ambient …
