This study addresses the potential use of phasor measurement units (PMUs) within electricity distribution systems, and was written to assess whether or not PMUs could provide significant benefit, at the national level. We analyze examples of present and emerging distribution-system issues related to reliability, integration of distributed energy resources, and the changing electrical characteristics of load. We find that PMUs offer important and irreplaceable advantages over present approaches.

Description:
The primary objective of this project is to design and demonstrate a prototype control system for damping inter-area oscillations in large-scale interconnected power systems. This is a collaborative effort involving the Bonneville Power Administration (BPA), Sandia National Laboratories, and Montana Tech University. The damping control strategy employs real power injections at strategically located points in the grid based upon real-time Phasor Measurement Unit (PMU) feedback.
