Keeping the lights on”, an axiom in power systems engineering has taken on a new level of complexity with increasing pressure on the existing network to deliver more power over existing infrastructure. The first part of the presentation will discuss High-Speed Digital Relaying Scheme for EHV /UHV transmission systems (345 kV and above) with half-cycle operating times. The second part of the presentation will discuss a scheme for real-time transient stability prediction system, and applying intentional islanding to prevent large-scale blackouts. With increasing environmental concerns over GHG emissions, more emphasis is being given to the generation technologies with a low carbon footprint. Conventional-type nuclear power plants (NPPs) are a reliable, clean energy source but have taken a back seat due to public reluctance, long construction periods, and large capital investment costs. Small modular reactors (SMRs), an emerging NPP technology, offer key advantages compared to conventional nuclear power plants in terms of smaller size, modularity, enhanced safety features, load-following capability, and suitability for wider energy applications. The third part of the presentation will discuss a dynamic model of SMR developed at the University of Saskatchewan including both the reactor-side dynamics and electrical side characteristics. A SMR -Renewable Energy Source (RES) hybrid energy system model will also be discussed in this part of the presentation. The studies show the proposed hybrid energy system can support the hosting of up to 50% renewables.

Presenter’s Bio: Ramakrishna Gokaraju received his Bachelor of Engineering degree (with Distinction) in Electrical and Electronics Engineering from the National Institute of Technology, Trichy, India in April 1992. He received the M.Sc. and Ph.D. degrees in Electrical and Computer engineering from the University of Calgary, Calgary, AB, Canada, in 1996 and 2000, respectively. From 1992-‘94 he worked with the Larsen & Toubro, Chennai, India as a graduate engineer and then later with the Indian Institute of Technology, Kanpur, India as a project associate. From 1999-2002, he was a Research Scientist with the Alberta Research Council and a Staff Software Engineer with IBM Toronto Lab. He joined the Department of Electrical & Computer Engineering at the University of Saskatchewan in 2003 and is currently a professor in the department. His current research works are in high speed digital relaying, controlled islanding to prevent large-scale blackouts and sustainable energy systems with SMR based generation.
