The objective is the development of a grid operations procedure using modal analysis for improving grid stability based on phasor measurements. To meet this need, modal analysis will be further explored in this project to develop real-time applications for grid operations. In prior work, we have extensively studied the mechanism of power grid low-frequency oscillations and identified the correlation of low damping and power flow of key transmission lines and generators. A MANGO procedure was established.
This project is enhancing algorithms for use in a mode meter that will detect, analyze, and potentially help localize forced oscillations in a power system. It also supports BPA in conducting probing tests for modal analysis in the Western Interconnection.
