PMU Data Analysis and Smart Grid Applications

Phasor measurement units (PMUs) are the most prominent devices for smart grid applications when it comes to the bulk part of the electric power system. Their ability to provide accurate, fast, and globally valid phasor computations throughout widespread areas can revolutionize the way the electric transmission grid is monitored and controlled. This presentation provides an overview of the synchrophasor network deployed and operated by the New York Power Authority since the early 90s. NYPA currently operates nine PMUs in its network and the collected data are currently being used in a number of R&D-type applications. Expansion plans are in place for new units to be integrated in the existing infrastructure in the next three years along with additional wide-area system monitoring applications.
