Self checking Phasor Data Concentrator
Unmet Need: Validation of synchrophasor measurements
The current techniques and phasor measurement units provide synchronized phasor measurements with desirable accuracy only in the steady state condition. During transient conditions, especially during power swings or during transient changes in power system frequency, both magnitude and phase angle...

Grid Control for Unknown Resonance Events (CURE)
Unmet Need: Detection and damping of resonance events in a power grid
Complex electric distribution systems cannot be perfectly modeled to reflect every duty cycle and configuration of each component which might come on-line. Recent instances of forced oscillations in wide area networks illustrate the difficulty in quickly locating their causes, and...
