Abstract
There have recently been a large investment in phasor measurement units (PMUs) in the US and several other countries.  As a new technology, there are still data quality issues such as missing and bad data that need to be resolved.  Power system control centers will use PMU data for real-time operation if the data is reliable.  The talk discusses the application of low-rank matrix completion methods to recover missing PMU data, by processing PMU data in spatial-temporal blocks.  The performance of the singular value thresholding (SVT) method and a proposed online method will be compared.  Real data from 53 PMUs will be used to demonstrate the techniques.  In addition, the application of the method to detect bad data or cyber-attack data will also discussed.
