NLR researchers are working to address protection issues introduced by the increasing use of inverter-based resources on power grids. Protection issues arise because inverters have fault characteristics that are significantly different from those of traditional synchronous generators. Synchronous. . prietary control schemes complicates the modeling of IBR behavior during faults significantly. This report provides a brief overview of research on IBRs'. . nd Texas. Synchronous generators and power electronic inverters show fundamentally different dyna ted by subject matter experts from Sandia National Laboratory, Siemens, and the Electric Power Research Institute (EPRI) in Spring 2023., a wholly owned subsidiary of Honeywell International, Inc.
