Existing Methods for Grid Strength Assessment and Role of Hydropower in Future Grids

Summary

The rapid integration of inverter-based resources (IBRs) into power grids presents a significant challenge to grid stability and reliability, particularly in regions with low system strength. This technical report, prepared by national laboratories for the U.S. Department of Energy, comprehensively analyzes existing methods for grid strength assessment and explores the critical role hydropower can play in stabilizing future grids. Through case studies and detailed analysis, the report highlights how hydropower, including operation as synchronous condensers, can enhance dynamic grid strength, thus contributing to the ongoing effort to maintain a secure and stable power system amidst the evolving generation mix.
