Precision Micro-Synchrophasors for Distribution Systems: A Summary of Applications

This paper describes high-level findings from an innovative network of high-precision phasor measurement units (PMUs), or micro-PMUs (μPMUs), designed to provide an unprecedented level of visibility for power distribution systems. We present capabilities of the technology developed in the course of a three-year ARPA-E funded project, along with challenges and lessons learned through field deployments in collaboration with multiple electric utilities. Beyond specific applications and use cases for μPMU data studied in the context of this project, this paper discusses a broader range of diagnostic applications that appear promising for future work, especially in the presence of high penetrations of variable distributed energy resources.
