Oscillation monitor has discovered many "new" oscillatory behaviors in power grids that could not be reproduced through traditional model based analyses. Initial investigations suggest that some oscillations are introduced by specific generators, either under special conditions or with failed components. Operators have a strong need to identify the sources in order to re-dispatch to damp the oscillations. The Oscillation Source Location is likely to be the first "Killer App" that will truly enable the operational use of the synchrophasor technology.
Both academia and industry have already had some initial experiences with this problem. The goal of this task force (TF) is to consolidate the previous achievements, reach consensus, and push the technology forward towards solving the problem. The TF's scope includes:
