Assessing a Grid with High Penetration of IBRs

Power systems are undergoing a rapid change in generation mix due to the growth of inverter-based resources (IBRs) such as wind, solar, and battery energy storage. The dynamic behavior of the Bulk Power System (BPS) that has typically been driven by synchronous machines is increasingly influenced or even largely determined by IBRs.
