About FNET/GridEye

Operated by the Power Information Technology Laboratory at the University of Tennessee, FNET/GridEye is a low-cost, quickly deployable GPS-synchronized wide-area frequency measurement network. High dynamic accuracy Frequency Disturbance Recorders (FDRs) are used to measure the frequency, phase angle, and voltage of the power system at ordinary 120 V outlets. The measurement data are continuously transmitted via the Internet to the FNET/GridEye servers hosted at the University of Tennessee and Virginia Tech. The Power IT Lab has developed several applications which use the FNET/GridEye data to study the power system, including:

• Event detection and location
• Oscillation detection
• Animations of frequency and angle perturbations
• Integration of renewables into the power grid
• Detection of system breakup or islanding
• Providing grid control input signals
• Prediction of grid instability and reduction of blackouts

FNET/GridEye Application Research

• Event location triangulation and estimation of event size
• Wide-area frequency and angle visualization and graphic display
• Dynamic clustering from FNET/GridEye data (frequency and angle)
• Inter-area oscillation mode identification
• Post-disturbance scenario reconstruction
• Line activity identification
• Use FNET/GridEye data to verify system models used in simulations.
• Adaptive under-frequency load shedding algorithm development using wide-area frequency information as inputs
• Wide area FACTS, PSS/HVDC control and coordination using FNET/GridEye as inputs for damping inter-area oscillations
• Monitoring DG impact on system operations, DG control
• Trending and system response speed analysis of static frequency for all interconnections
• Monitoring tool for Compliance of NERC frequency response requirements
