About

Dr. Gregory Kish received the BESc degree in electrical engineering from the University of Western Ontario, where he was awarded the Governor General’s Silver Academic Medal, and received both his MASc and PhD degrees from the University of Toronto. From 2002 to 2005, Dr. Kish worked in industry where he was involved in many projects related to electrical energy systems, ranging from PLCs, electric drives and rotating machines to high-voltage electrical substations. He joined the University of Alberta in 2015.

Dr. Kish is a senior member of the IEEE, and a member of the IEEE Power and Energy Society (PES), IEEE Power Electronics Society (PELS) and IEEE Industrial Electronics Society (IES). He is also a member of CIGRE. From 2017-2021, he was involved with CIGRE international Working Group B4.76 "DC-DC converters in HVDC Grids and for connections to HVDC systems". Dr. Kish is a registered Professional Engineer in Alberta (APEGA) and Ontario (PEO).

Research

Dr. Kish's research team carries out research at the intersection of power electronics and power systems, with a focus on addressing the many challenges arising due to the evolving landscape of electric power grids. Key activities include the development and application of new power electronic converter systems to enhance grid functionality, at both transmission and distribution levels, as well as to facilitate the large-scale integration of renewable energy resources. An emphasis is placed on applications involving high-voltage dc (HVDC) and medium-voltage dc (MVDC) systems and hybrid ac/dc grids. Interests also include microgrids, grid connected energy storage and other systems concepts and technologies falling under the broad “smart grid” label.

Current Research Activities

• Medium- to high-power modular converter systems for dc and ac grids
• Grid integration of renewable energy systems
• Dc power networks, including HVDC grids and MVDC distribution systems
• Mixed (i.e. hybrid) ac/dc systems
• Fault blocking converters for dc grid applications
