key trend within ERCOT and the industry. In conjunction
with this, the ERCOT Reliability and Operations Subcommittee (ROS) developed a goal for 2014 to "evaluate and
determine synchrophasor requirements and address any
needed changes in protocols and guides." This goal was
intended to be met, in part, by the formation of the Phasor
Measurement Task Force (PMTF), which was kicked off
in November 2013.
Representatives from ERCOT, TOs, generator owners (GOs), the North American Synchrophasor Initiative
(NASPI), and CCET were in attendance at the PMTF kickoff meeting. NASPI and CCET representatives gave presentations on the status of synchrophasor technology within the
broader electric industry, as well as the success of the Discovery Across Texas (DAT) smart grid demonstration project
that employed synchrophasor technology and advanced analytic tools to monitor wind dynamics, enhance transmission
operations management practices, and improve grid reliability. The group elected its leadership and confirmed the ROS38

identified charter, which consisted of eight key issues as the
PMTF's main scope of work.
For the PMTF to complete its work, ERCOT stakeholders
and industry experts were invited to attend and present material to the group on technical topics including PMU hardware,
PDC design, situational awareness software, and model validation techniques. Efforts within other North American Electric
Reliability Corporation (NERC) regions were also reviewed
to discover best practices. Ultimately, the group narrowed its
focus to the three most beneficial use cases:
✔ oscillation detection and alarming
✔ generator model validation
✔ postdisturbance analysis and reporting.
These use cases were chosen, in part, based on ERCOT's
prior experience with the synchrophasor infrastructure
installed as part of the DAT project.
To support the identified use cases, the PMTF worked on three
key deliverables over the course of 2014: the ERCOT Synchrophasor Technology Assessment, the ERCOT Synchrophasor
