This webinar was presented by Dr. Thomas Overbye, Texas A&M University. Abstract: Except for a brief time around 1970, the North American Eastern and Western grids have operated asynchronously from each other, with power transfers only possible through a few back-to-back HVDC ties. However a recent study has shown that an AC interconnection may be …

The 53rd North American Power Symposium will be held at Texas A&M University, College Station, Texas, from November, 14—16, 2021. NAPS, a student-centric conference, has been bringing together students, faculty, and researchers in the power and energy systems area since its inception in 1969. The purpose of this symposium is to provide a forum for …
The course is designed to provide state-of-the-art introduction of data science and machine learning that is tailored for power engineering applications. The electricity industry is transforming itself from a hierarchical, passive, and sparsely-sensed engineering system into a flat, active, and ubiquitously-sensed cyber-physical system. The emerging multi-scale data from synchrophasors, smart meters, weather, and electricity markets …
In this talk, the speaker, Dr. Kate Davis, will present a briefing on our Cyber-Physical Resilient Energy Systems (CYPRES) project funded by the US Department of Energy Cyber Security for Energy Delivery Systems (DOE-CEDS) program. The vision of CYPRES is a cyber-physical energy management system that would allow the energy system to be modeled and …
The large grid of high-voltage transmission lines and transformers that forms part of a bulk electric power delivery system can be characterized by a number of metrics from graph theory, network science, computational geometry, and engineering analysis. Example metrics include the distribution of the number of links connected to each node, the length of the …
Geomagnetic disturbances (GMDs) caused by solar coronal mass ejections can induce quasi-dc currents in the ac power grid, potentially leading to harmonics, transformer heating, and increased reactive power losses in the system. Voltage collapse has been recognized as the key risk posed by these geomagnetically induced currents (GICs) the grid. This talk will first briefly …
The power grid is a vast and interconnected cyber-physical system for delivering electricity. Treating the grid as a cyber-physical system requires new perspectives, including analysis techniques as well as operating procedures. Attacks on the grid could detrimentally affect public health and safety, yet its cyber infrastructure is not currently included in the intense analysis of …
Worldwide consumption of electricity is expected to nearly double over the next two-and-a-half decades. International Energy Agency (IEA) predicts that meeting this demand for power will require over 5,000 GW of new electricity generating capacity (including replacement capacity) at a cost of over $5 trillion. The new plants will require an additional $6 trillion worth …
The topic of Big Data and associated analytics is relatively new (last 15 years). It became prominent as huge amounts of data became available through space exploration, weather forecasting and medical biogenetic investigations. Social media and outlets such as Google, YouTube, Facebook, Amazon and others have also faced similar problems of handling huge data sets. …
An ongoing power system challenge is how best to utilize and ultimately present information to a human user derived from either actual system sensors or engineering studies for large-scale electric grids. In operations this data might come from measurement systems such as SCADA or PMUs, while in a study context it might be generated by …
