内容简介 This talk consists of two parts. The first part is entitled “Recovery of Missing Synchrophasor Data via Adaptive Filtering.” This is an ongoing research topic at RPI to improve the data quality of PMU data, so that the synchrophasor data can be used reliably by control room applications.  In previous research, RPI has proposed the use of low-rank matrix completion to recovery missing PMU data, from information available in neighboring substations.  (Low-rank matrix completion methods have been developed for video processing and consensus analysis.) In this new approach, the low-rank property is translated into an adaptive filter based on windows lasting seconds.  A stability condition has also been established for the filter.  The second part is entitled “an On-line Thevenin Equivalent Estimation Algorithm.” This is a continuation of our research on developing equivalent circuit models from power system measured data for voltage stability analysis.  Thevenin Equivalent model estimation using measured data from real systems is fraught with problems and can yield inconsistent results.  During periods in which the load and generator pattern does not change much, the estimated parameters will be driven mostly by measurement noise.  In this new online method, a thresholding method and a forgetting factor method are used to reduce the variations of the Thevenin Equivalent model parameters.
