Recently IEEE PES Queensland Chapter has successfully organized a PES distinguished lecture (DL) event on Feb. 26, 2021 on Zoom platform. Dr. Jessica Bian, an IEEE PES distinguished lecturer, delivered the distinguished lecture titled ‘Grid Reliability and its Vital Signs’. She discussed on power system condition monitoring and risk assessment using vital signs. Frequency, voltage, and network events are vital signs, which may tell us about the bulk power system. In her lecture, Dr. Jessica Bian provided insights on the underlying vital signs of grid health condition.
Dr. Bian is widely recognized as a pioneer in the field of Power System Reliability. She has spearheaded the electric industry’s reliability metrics and grid risk assessment. Under her leadership, a total of 18 industry-wide reliability indicators were established to determine grid reliability, adequacy, and associated risks. Currently, Dr. Bian is the Vice President of Grid Services at Grid-X Partners. She was with the Federal Energy Regulatory Commission, Washington, D.C. Previously, she was the director of performance analysis at the North American Electric Reliability Corporation (NERC) in Atlanta, Georgia. She received her Ph.D. degree from Tulane University, New Orleans, Louisiana. She has had more than 70 articles published, and she received the 2014 PES Wanda Reder Pioneer in Power Award for her technical achievements. She was the PES Secretary during 2016-2019 and now serving as the 2020-21 PES President-Elect.
The virtual session was well received by 60 attendees from both academics and practitioners. In the lecture, Dr. Bian provided insights on the underlying vital signs of a grid health condition, such as – frequency, voltage, and network events, which indicate the bulk power system. The session was mainly focused on power system condition monitoring and risk assessment using vital signs.
In the session, Dr. Bian explained the need to investigate the vital signs underlying the power system’s health and the methods to accurately assess these signs. She provided an opportunity for the attendees to explore the reliability aspects of the bulk power system so that they can develop a systematic, integrated understanding of how to assess the bulk power system reliability. In her lecture, Dr. Bian also introduced several additional indicators including energy emergency alerts, transmission outage rates, protection system operations, and resource reserve margin. Most importantly, Dr. Bian provided ranges, trends, and driving factors that influence changes in these indicators.
Many attendees said they would like to incorporate the vital signs introduced in the lecture as indicators to improve the visibility of a power system’s health condition.
