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:
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.

Abstract:
This project is focused on developing a fundamental understanding of the impact of network delays and data drops using an approach that is applicable to a variety of Cyber-Physical Systems (CPS). An example of such a CPS is the power grid which includes large-scale deployment of distributed and networked Phasor Measurement Units (PMUs) and wind energy resources.
