Protection challenges with high penetration of Inverter Based Resources (IBRs) - Part 1: Transmission System

This panel presents various topics related to power system protection challenges faced by electric power companies due to rapid increase in penetration levels of IBRs in Transmission System. The following main topics will be presented: ¢ An update on the upcoming IEEE P2800”Standard for Interconnection and Interoperability of Inverter-Based Resources Interconnecting with Associated Transmission Electric Power Systems with main emphasis on voltage ride-through capability and performance requirements will be presented. (Manish Patel) ¢ Presentation based on the work of IEEE Power system Relaying Committee C24 Working Group: Modification of Commercial fault calculation programs for wind turbine generators. ¢ Transmission Line Protection for Systems with Inverter Based Resources: Electromagnetic transients program (EMTP) simulation results to investigate the protective relay response to faults on the modeled power system with the different inverter types are presented. ¢ Reliability risks to conventional line protection schemes using real life examples of short circuit currents on lines, supplied by sources having converter or inverter interfaces. Examples will be used from the protection schemes adopted by a North American utility company for lines interconnecting sources with converter or inverter interfaces.
