Episode #10 | Big Data Analytics and the Brilliant Grid
This episode of The Energy Exchange is focused on data connectivity between applications and the information it generates that goes beyond Big Data and Smart Algorithms, as well as how IT plays a key role in using the information received from connected systems. Anyone who has purchased an item, or even just simply looked at certain items online, has experienced the magic of related sug...
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...

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...
