Abstract
"The move toward a ""smarter"" electric grid, along with increased renewable penetration, has motivated the need for increased power system visibility. This is due to the fact that these energy sources introduce transients that previously were not as common or pronounced within the distribution system. Increased distribution system observability can be realized with the implementation of Phasor Measurement Units (PMUs), which measure the AC voltage and current traveling throughout the grid. However, questions related to both the economic investment and the actionable informational gains are the biggest impediments to the installation of more PMUs within the distribution system. A relatively low-cost alternative to many of the commercially available PMUs is the Frequency Disturbance Recorder (FDR), which measures voltage at the 120 V-outlet level. This research proposes using the voltage information obtained from FDRs to validate the benefits of installing PMUs at the distribution level; the work has looked into what system events, both transmission and distribution, can be seen at the distribution level. The thesis begins by providing a background on the state of the distribution system and the effects of new grid technologies. Afterward, the FDR will be introduced, and an example of the information that can be obtained from the data will be shown."
