An Open-Source Library of Phasor Measurement Unit Data Capturing Real Bulk Power Systems Behavior

The Grid Event Signature Library: An Open-Access Repository of Power System Measurement Signatures

“…About two minutes of data on either side of event instances were retained to allow the testing of temporal localization algorithms. Further details about the data curation, obfuscation, and labeling processes are provided in [16].…”

“…In the third use case example, an example of feature engineering for ML/AI applications is presented in the form of the Spectral Correlation Function (SCF), [23]. The fourth and final use case describes how PMU data housed in the GESL is used for characterizing noise patterns in both the U.S. Western and Eastern interconnections, as well as a brief discussion on algorithm benchmarking, [16], [24]. All works presented in this section may be found in more detail in the appropriate references.…”

“…In this section, two brief examples of different ways the PMU data in GESL may be used are provided. Further details regarding their implementation and background can be obtained from [16], [24].…”

“…Benchmarking the performance of algorithms: A promising use of the GESL data can be in benchmarking the per- formance of novel algorithms against the existing state of the art, similar to how the MNIST dataset is often used to evaluate the performance of image classification algorithms. In [16], a subset of the GESL PMU measurements was used to compare the performance of two missing data imputation methods using low-rank matrix-completion strategies in terms of accuracy and computation speed. Similarly, in [24], using ambient and forced oscillation events from the GESL, the performance of a novel threshold-setting method for oscillation detection was compared to the industry convention, and found to be superior.…”
