Venkata Dinavahi received the B.Eng. degree in Electrical Engineering from the Visveswaraya National Institute of Technology (VNIT), Nagpur, India, in 1993, the M.Tech. degree in Electrical Engineering from the Indian Institute of Technology (IIT), Kanpur, India, in 1996, and the Ph.D. degree in Electrical and Computer Engineering from the University of Toronto, Ontario, Canada, in 2000. Currently he is a Professor with the Department of Electrical and Computer Engineering, University of Alberta, Edmonton, Alberta, Canada. His research interests include realtime simulation of power systems and power electronic systems, electromagnetic transients, devicelevel modeling, largescale systems, and parallel and distributed computing. He was the founding chair of the IEEE Power and Energy Society (PES) Task Force on Interfacing Techniques for Simulation Tools from 2006 to 2014. He actively participates in several IEEE PES committees notably in the Working Group on Modeling and Analysis of System Transients. He has published over 150 papers in peerreviewed international journals and over 60 articles in international conference proceedings. He is a Fellow of IEEE. He was the recipient of the 2018 Outstanding Engineer Award from the IEEE PES/IAS Northern Canada Chapter. He is a member of CIGR (International Council on Large Electric Systems) and a Professional Engineer in the Province of Alberta.

Ning Lin received the B.Sc. and M.Sc. degrees in Electrical Engineering from Zhejiang University, China, in 2008 and 2011, respectively, and the Ph.D. degree in Electrical and Computer Engineering from the University of Alberta, Canada, in 2018. From 2011 to 2014, he worked as an engineer on power system automation, flexible AC transmission system (FACTS), and highvoltage direct current (HVDC). Currently, he is a postdoc assistant researcher at the University of Alberta. His research interests include power electronics, realtime simulation of power systems, and highperformance computing of integrated AC/DC grids.

Promising advances in highpower electronics and the challenges facing modern power system operation in terms of integration of largescale renewable generation and energy storage is necessitating the construction of highvoltage direct current (HVDC) transmission worldwide. Meshed multiterminal DC grids are transporting bulk energy over longer distances, interconnecting farflung asynchronous AC network, and are being operated with higher redundancy, efficiency, and reliability. Since the conception of realtime analog simulators (known as transient network analyzers (TNAs)) and subsequently realtime digital power system simulators in the 1970s through to the 1990s, one of their principal applications has been for the testing of control and protection functions in a hardwareintheloop (HIL) configuration for HVDC systems prior to their commissioning. Currently, realtime digital electromagnetic transient (EMT) simulators are used in every sector of electrical power chain: generation, transmission, distribution, and consumption. Moreover, realtime EMT simulators are also frequently employed in the transportation (automotive and railway traction), aviation, and marine industries, wherein the electrical systems share many structural and functional commonalities with terrestrial ACDC networks. While the design, testing, and commissioning of local control and protection functions of system equipment is the primary objective of realtime EMT simulation, it is also paramount for global dynamic and interactive studies of largescale power systems for widearea control, protection, and system operator training. EMT simulation of large ACDC grids in real time is a significant challenge due to the need for detailed devicelevel modeling of system components while simultaneously reproducing the systemlevel interactions accurately by accommodating large system sizes. These contrasting requirements place an enormous burden on the simulator latency constraints and the hardware selection for implementing the realtime simulation.
