Phasor measurement units (PMUs) have been deployed at over 2,500 locations across the nation’s bulk power systems. Due to these PMU measurements, grid owners and operators now possess unprecedented quantities of data detailing the condition of the grid. Robust tools are needed for the analysis and discovery of the information hiding within the growing archives of PMU data, so future PMUs can contribute even more to the efficient, safe, and reliable operation and design of the nation’s electric system.
In 2019, the Department of Energy (DOE) selected eight projects to explore the use of big data, artificial intelligence (AI), and machine-learning technology and tools on PMU data to identify and improve existing knowledge, and to discover new insights and tools for better grid operation and management.
For more information, please view this press release and fact sheet.
The projects received a first-of-its-kind dataset that:
- Covered a significant number of PMUs and substations in each of the three U.S. interconnections;
- Covered multiple years and included event logs;
- Consisted of real field data from a variety of sources that includes errors, inconsistencies, quality levels, and flaws; and
- Was anonymized to reduce the possibility of exposing potential information about power system operational vulnerabilities.
A subset of this data is publicly available via OE’s Grid Event Signature Library (ornl.gov) The subset is stored under Provider 9 and Provider 10.

The projects have been completed and below are their final reports along with links to some of the publications supported through this research and related presentations. After the completion of the projects, PNNL conducted a meta-analysis of the projects and created a report that summarizes the key findings across the projects.
