The goal of the project is to develop techniques that will allow detection and correction of relay misoperations in electric grids. The work from NDSU in (2017-2018): 1) advanced the concept of energy function traces to detect disturbance events in power systems including: temporary and permanent line faults, load loss and excitation failures 2) developed SVD/PCA methods to determine the sensitivity and accuracy of energy-based methods.

Visible to the public Online Robust PCA for Malicious Attack-Resilient Wide Area Monitoring

Submitted by nilanjgec on Tue, 01/22/2019 - 7:46pm. Contributors:

This poster presents a method for detecting and correcting malicious data corruptions in PMU measurements. Detection of malicious injections is formulated as a compressed sensing problem and the actual signals are recovered using an online robust PCA-based algorithm. Different patterns of malicious injection attacks on PMU data are considered and the effect of corruption and reconstruction using the algorithm is analyzed on wide-area mode metering application. The performance of the proposed algorithm has been evaluated with different subspace selection.
