Benefit of Grid Edge Synchronized Measurements

The talk will provide an overview on the effort of power grid wide-area monitoring and observations that were made possible from the grid edge synchronized data.  The critical roles of wide-area phasor measurement in situation awareness, operation, and control will be discussed. The concept of electromechanical wave propagation in power grid will be demonstrated using measurement data collected from the actual grids. Applications of time synchronized data in event location, oscillation location detection, model validation, and high renewable grids will be discussed.
