Electromagnetic Transient Simulation: Moving to the Mainstream [Technology Leader]

Electromagnetic transient (EMT) simulation has moved from a tool used for a few specialist applications, such as insulation coordination, to becoming a common tool for interconnection studies for inverter-based resources (IBRs). Historically, many utilities had few, if any, engineers with a background to perform EMT studies. Today, the proliferation of inverter-based generation and storage resources makes EMT simulation a critical tool for protection and planning studies.
