Abstract
This report serves as an addendum to the report “2015 Eastern Interconnect Baselining and Analysis Report” (Amidan, Follum, and Freeman, 2015). This addendum report investigates the following:
  • the impact of shorter record lengths and of adding a daily regularization term to the date/time models for angle pair measurements,
  • additional development of a method to monitor the trend in phase angle pairs,
  • the effect of changing the length of time to determine a baseline, when calculating atypical events, and
  • a comparison between quantitatively discovered atypical events and actual events.
