Anyone who has purchased an item, or even just simply looked at certain items online, has experie...
Effective Angle Prediction Algorithm for Utilization of PMU Data: Toward Prevention of Wide Area Blackouts
Published via IEEE Xplore
Abstract
Advanced state estimation and angle prediction algorithms utilizing the data measured by Phasor Measurement Units (PMU) can limit the spread of wide area blackouts. Advanced prediction analysis provides information on the overall condition of the power system and allows for the most efficient remedial action...

Episode #8 | Taking Knowledge to the Next Generation
While at DistribuTECH 2019, Host Ron Chebra had the opportunity to interview Rick Bush, T&D World and Mark Johnson, Utility Analytics Institute and talk about the next generation of engineers in our industry - how to make an environment where they want to work and play. Plus, they chat about how to ensure we don't create a swamp out of the data we're collecting. All th...
A Benchmark Test System to Evaluate Methods of Harmonic Contribution Determination
Published via IEEE Xplore
Abstract
Harmonic distortions at a point of common coupling (PCC) are caused by the harmonic sources in both supply system and customer facilities. In order to verify compliance with harmonic limits for an operating facility, it is essential to determine the contribution of a facility to the harmonic distortions measured at the PCC. Over th...
