The overarching goal is to employ a Wide-Area measurement-aided supervisory layer for correcting maloperation in relays, which can prevent system-wide blackouts. PSU's task in this project is to ensure distinction between disturbance outlier and anomalous outlier in such Wide-Area measurements. This poster presents a Principal Component Analysis (PCA)-based method for online characterization of outliers in Wide-Area synchrophasor measurements. To that end, a linearized framework is established to analyze dynamical response from a system under nominal and off-nominal (e.g.

ABSTRACT: The current approach to protect users from phishing attacks is to display a warning when the webpage is considered suspicious. We hypothesize that users are capable of making correct informed decisions when the warning also conveys the reasons why it is displayed.

Abstract:
Protective relays play a crucial role in steering the dynamics of the electric grid during stressed system conditions. However, as some blackout logs have shown, relay mis-operations during stressed conditions can trigger a cascade eventually leading to a blackout. Currently, there is no way to correct such mis-operations, should they occur. We propose the use of wide-area information to supervise relay operation, especially those attached to generator units and critical transmission lines.
