Each year we offer a one-day professional seminar on a high-interest topic in system protection. This year we will be covering two half-day topics: Impact of Renewables on System Protection and Introduction to IEEE Std 2800-2022. These topics will be presented by Aboutaleb Haddadi, B.Sc., M.Sc., Ph.D., SMIEEE, Senior Engineer Scientist with the Grid Operations and Planning R&D Group at EPRI, in Knoxville, Tennessee and Manish Patel, Ph.D., P.E., Chief Engineer in the Protection & Control Applications department at Southern Company Services, in Forest Park, Georgia, respectively.
Impact of Renewables on System Protection
The increased integration of renewable inverter-based resources (IBRs) such as wind, solar, and battery storage in the bulk power system leads to challenges for reliable operation of system protection. Traditionally, protective relays have been designed and set with the expectation of high fault currents and dynamic behavior dominated by synchronous generators. Short circuit analysis tools and models have also been developed over several decades around these assumptions. Nevertheless, these assumptions may no longer hold under IBRs, due to the different short circuit and dynamic characteristics of these resources. Specifically, IBRs cannot provide fault currents significantly higher than their nominal current without additional increase in their power electronic hardware rating. Further, their fault response is highly dependent on often proprietary and non-universal inverter control scheme. These differences may lead to misoperation of protective relays, i.e., they may operate unnecessarily/unpredictably or fail to operate where they should. Further, traditional short circuit analysis methods and models may need to be revised to adequately capture the short circuit response of a renewables-dominated power system. The ultimate goal is to ensure that the protection system of the future renewables-dominated power system achieves the same level dependability and security as today’s protection system for the SG-dominated power system. This seminar talks about the latest developments on the impact of IBRs on system protection, IBR short circuit modeling, and short circuit analysis methods under high level of IBRs. Specifically, the seminar will focus on:
Aboutaleb received his B.Sc., and M.Sc. degrees in electrical engineering from Sharif University of Technology, Tehran, Iran in 2007 and 2009, respectively, and his Ph.D. degree in electrical engineering from McGill University, Montreal, Canada in 2015. His work at EPRI focuses on renewables grid integration studies, transmission system protection and the impact of renewables, and power system modeling and simulation. Aboutaleb is also the chair of the CIGRE Working Group C4.60 on Generic EMT Modeling of Inverter-Based Resources and a Senior Member of IEEE.
- Updates on the impact of IBR on transmission system protection
- IBR short circuit model considerations for VCCS tabular model
- Potential need for load modeling in short circuit studies with high level of IBRs
- Limitations of classical phasor-domain analysis and need for electromagnetic transient-type (EMT) simulation for short circuit analysis of an IBR-dominated power system
- Impact of distributed energy resources (DERs) on distribution system protection
Introduction to IEEE Std 2800-2022 - Interconnection and Interoperability of Inverter-Based Resources (IBR) Interconnecting with Associated Transmission Electric Power Systems
The IEEE SASB recently approved IEEE Standard 2800-2022 which establishes “technical minimum requirements for the interconnection, capability and performance of inverter-based resources (solar, wind & storage plants, including those connected via VSC-HVDC like offshore wind) interconnected to transmission and sub-transmission systems.” This presentation will review scope, purpose, and specified requirements with focus on voltage ride-through (including consecutive voltage dips, transient over-voltage) and fault current injection requirements. Variations in capability and performance requirements considering limitations of various technologies will also be discussed.
Manish received his B.E. from B. V. M. Engineering College, V. V. Nagar, India in 2000 and Ph.D. from Clemson University, Clemson, South Carolina in 2009, both in electrical engineering. He joined Georgia Power Company in 2006 as a Protection & Control Applications Engineer. Since then, he has spent 9 years in Protection & Control Applications and 6 years with the Transmission Planning - Stability group. Manish is an active member of the IEEE PSRC, chairing the D39 working group tasked with revising the IEEE Std C37.104 at PSRC over the last 5 years. Currently, he is a vice chair of the IEEE P2800 and secretary of the IEEE P2800.2 working groups. Manish is a registered Professional Engineer in the state of Alabama.
