The Use of Synchrophasors to Understand What Happened to the Power Grid During the Winter Storm Uri Event


The winter event that occurred in February of 2021 was one of the costliest winter storms on records.  The storm resulted in over 170 million Americans being placed under various winter weather alerts being issued by the National Weather Service in the United States across the country and caused blackouts for over 9.9 million people in the U.S. and Mexico, most notably the 2021 Texas power crisis. The blackouts were the largest in the U.S. since the Northeast blackout of 2003.

This lunch and learn with cover how the use of Dr. Grady’s Texas Synchrophasor Network (TSN) and how the use of data, oscillography, etc. helped paint the picture and explain the sequence of events that took place on the grid during the duration of the storm.

This event will provide two (2) CEHs.

Dr. Mack Grady, PE of Baylor University


Dr. Mack Grady, PE is a professor at Baylor University since 2012, and was awarded Professor Emeritus status at U.T. Austin in 2013 for his service there since 1983.  Dr. Grady is an IEEE Fellow for “Contributions to the analysis and control of harmonics and electric power quality.”

In 2007, with the help of Schweitzer Engineering Labs, he started the “Texas Synchrophasor Network” (TSN) with three stations in Texas and one is New Mexico.  The TSN moved with him to Baylor in 2012, additional stations were added in the Eastern Grid, including three stations belonging to OG&E.  Also, SEL, ERCOT, OG&E, Austin Energy, U.T. Austin, U.T. Rio Grande Valley, and several other individuals continue to support the effort.

His two other present-day research topics are 1. working as part of the HEMP-E3 research team of DoD-DTRA and their affiliated ARA research organization since 2008, and 2. assisting ERCOT with grid topics most important to them.
