The Impact of Inverter-Based Resources (IBR) on Protection System
Protection systems are designed to detect and isolate faults from power systems. Protection engineers are very comfortable with designing the protection systems for the grid that has been dominated by synchronous machines for years. Today, the increased use of renewable energy resources such as wind and solar, which supply power via inverters, are being added to the grid. These IBRs add a new challenge to the protection of power systems. The fault contribution from a small percentage of IBRs may not have a substantial impact on the grid and its protection, but a larger penetration will. The presentation mainly focuses on the impact of IBRs directly connected to the Bulk Power System (BPS). The presentation is organized to provide its audience with an awareness of the issues with low fault current contribution due to the high penetration of IBRs and challenges with the modeling of IBRs in short circuit programs. It also compares the short circuit results for an IBR-dominated system from a couple of commercial fault calculation programs.

Speakers
Steve Miller, P.E., Looja Tuladhar, P.E., PhD and Koustubh Banerjee, P.E.
Biography:
Mr. Miller has nearly 40 years of experience in the analysis and planning of electric utility transmission systems and the design and development of associated software programs. As a consultant Mr. Miller has been responsible for assisting generators with the interconnection process. Occasionally these projects materialize and when they do the interconnection concepts developed Mr. Miller and his colleagues have been implemented. Outside of his interconnection expertise, Mr. Miller has three engineering degrees from the University of Michigan and has performed all manner of study projects involving the grid ranging from cascade failure analysis, generation adequacy, to economics studies, special studies etc. Mr. Miller works successfully at the boundary of engineering and legal, regulatory, and business issues successfully developing and presenting testimony and positions.
Mr. Tuladhar has broad experience in protective relaying and power system analysis, including short circuit studies, coordination studies, relay settings, transient analysis, and planning studies. He also has experience in designing electrical distribution circuits and performing electrical energy audits. He holds the Doctor of Engineering degree from Cleveland State University, Cleveland, Ohio.
Koustubh Banerjee is an Electrical Engineer at Commonwealth Associates, Inc. He received his Master’s degree also in electrical engineering from Arizona State University in 2014. He has been in the power industry for more than 5 years. At Commonwealth he has worked on various relay settings and protection coordination projects for utilities. He is also experienced in transmission planning and NERC MOD and PRC compliance studies.
