DESCRIPTION:This presentation explores the dynamics of wide-area oscillatio
 ns in power grids and their impact on grid stability\, particularly under 
 high penetration of Inverter-Based Resources (IBR). This is part of ongoin
 g three-year research project\, Wide-Area Oscillation Assessment and Trend
 ing Analysis\, funded by DOE Office of Electricity Advanced Grid Modeling 
 program. Wide-area oscillations carry crucial information about system sta
 bility. While well-damped oscillations are often contained\, strong oscill
 ations can signal impending stability issues\, reducing system performance
 \, increasing equipment wear\, and potentially causing generation tripping
  or grid breakup. Adequate damping of key oscillation modes is essential f
 or reliable grid operation. Conventional analysis has focused on large syn
 chronous generators\, but the rising penetration of renewable generation a
 nd active loads is driving observable changes in oscillatory behavior. A s
 ystematic study reveals that high IBR penetration correlates with lower da
 mping ratios of inter-area modes\, while heavier loads correlate with lowe
 r oscillation frequencies. Without proper control and coordination\, high 
 IBR penetration could exacerbate these oscillations\, posing risks to grid
  stability. To mitigate these risks\, we developed and tested control stra
 tegies for IBRs to improve oscillation damping. Leveraging our prior exper
 ience in grid oscillation research\, we focused on designing control algor
 ithms for both grid-forming and grid-following IBRs. Study results show th
 at these control strategies can enhance the stability of power grids with 
 high renewable generation.\n\nCo-sponsored by: CH06148\n\nSpeaker(s): Ning
