WARP- Wide Area assisted Resilient Protection

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. The work from PSU further established singular value perturbation methods to discriminate anomalous “outliers” from genuine system-induced events in PMU data streams. The work from NMSU developed and tested a dynamic simulation model to mimic and retrace principal events in the 2011 southwestern blackout. These results will be used for validation of all theories developed during the project. Current work is focused on integrating these tools and theories followed by validation through simulation and field data.
