Oscillation Workshop Oscillation Workshop Hosted by WECC, Salt Lake City

A 2-day workshop covering theory and best practices for oscillation monitoring and detection was led by Professors Dan Trudnowski and Matt Donnelly of Montana Tech, John Pierre (University of Wyoming), and EPG’s Kevin Chen and Neeraj Nayak took place in August, 2017. Participants were major ISOs and utilities

Gridsmarts ReportsNYISO tracks PMU performance with GridSmarts Reports

NYISO manages and tracks PMU performance through monthly reports from GridSmarts. Report includes overall PMU performance as well as breakdown of bad data for each PMU by error for use in data management business process.

PhasorNXTERCOT implements Grid Resiliency Solution with PhasorNXT

ERCOT is using PhasorNXT for a real time grid monitoring system independent of EMS/SCADA - providing a grid resiliency solution in the event of EMS/SCADA shutdown due to equipment failure or cyber-attack. PhasorNXT system includes DataNXT for data quality validation, enhanced Linear State Estimator

eLSEPeak RC improves line impedance in its network model using EPG’s eLSE

The eLSE was used to identify and remediate faulty impedance values in their network model - used for traditional state estimation and contingency analysis. Peak RC is also using the eLSE for enhanced visibility beyond available PMUs; data conditioning and network model validation.
