S-86G Project Summary 

Input-Output Metrics for the Power-Grid’s Swing Dynamics

Summary New technologies are providing new opportunities for wide-area control of poorly-damped oscillations in the bulk power grid. A foundational need in wide-area controller design is the assessment of input-output channel properties of the power system dynamics, in addition to its internal or modal properties. The purpose of this project is to undertake a comprehensive analysis of a suite of input-output metrics for the system dynamics, from both numerical and graph-theoretic perspectives. The metric analysis will then be used to develop model-reduction techniques that maintain key input-output properties, and to support estimation of channel properties from ambient synchrophasor data.
