This presentation explores the dynamics of wide-area oscillations in power grids and their impact on grid stability, particularly under high penetration of Inverter-Based Resources (IBR). This is part of ongoing three-year research project, Wide-Area Oscillation Assessment and Trending Analysis, funded by DOE Office of Electricity Advanced Grid Modeling program. Wide-area oscillations carry crucial information about system stability. While well-damped oscillations are often contained, strong oscillations 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 for reliable grid operation. Conventional analysis has focused on large synchronous generators, but the rising penetration of renewable generation and active loads is driving observable changes in oscillatory behavior. A systematic study reveals that high IBR penetration correlates with lower damping ratios of inter-area modes, while heavier loads correlate with lower 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 strategies for IBRs to improve oscillation damping. Leveraging our prior experience in grid oscillation research, we focused on designing control algorithms for both grid-forming and grid-following IBRs. Study results show that these control strategies can enhance the stability of power grids with high renewable generation.
