Kallyan of Sen Engineering Solutions, Inc.

Electric power grid around the world is being modernized to integrate renewable energy sources, such as wind and solar in an unprecedented scale. This brings unforeseen challenges in integration of inertia-less and intermittent renewable energy sources with a legacy grid that was built with rotating machinery. An opportunity lies ahead to upgrade the power flow controllers from the traditional reactance regulator and phase angle regulator to a modern-day impedance regulator that is capable of regulating the line voltage and controlling the active and reactive power flows in the line independently.

The presentation is designed to provide the basic principles of power flow control theory, an overview of the most commonly used power flow controllers, and future trends. The audience will hear from an expert who actually designed and commissioned a number of power electronics-based FACTS controllers since their inceptions in the 1990s.

Biography:

Kalyan Sen is the President & Chief Technology Officer of Sen Engineering Solutions, Inc. (www.sentransformer.com) that specializes in developing SMART power flow controllers—a functional requirements-based and cost-effective solution. He is also an Adjunct Teaching Professor at WPI. Kalyan worked 33 years in academia and industry. He was a key member of the Flexible Alternating Current Transmission Systems (FACTS) development team at the Westinghouse Science & Technology Center for which he became a Westinghouse Fellow Engineer. He contributed to concept development, simulation, design, and commissioning of FACTS projects at Westinghouse. He conceived some of the basic concepts in power flow control technology for which he was elevated to the IEEE Fellow grade with the citation: for the development and application of power flow control technology. He is the Co-inventor of the Sen Transformer.

Kalyan has authored or coauthored more than 25 peer-reviewed publications, 8 issued patents, 2 books, and 3 book chapters in the areas of power flow control and power electronics. He is the Coauthor of the book titled, Introduction to FACTS Controllers: Theory, Modeling, and Applications (978-0-470-47875-2), IEEE Press and John Wiley & Sons, Inc. 2009, which is also published in Chinese and Indian paperback editions. His second book is titled, Power Flow Control Solutions for a Modern Grid using SMART Power Flow Controllers (ISBN: 978-1-119-82435-0), IEEE Press and John Wiley & Sons, Inc., 2022.

Kalyan has served many organizations. He has been serving as an IEEE Power & Energy Society (PES) Distinguished Lecturer since 2002. In that capacity, he has given presentations on power flow control technology more than 190 times in 19 countries. He is an AdCom Member of the Power Electronics Society (PELS). He is the IEEE Division II Representative to the Board of Governors of Society on Social Implications of Technology (SSIT).

In 2003, he reestablished the Pittsburgh Chapters of the PES and the Industry Applications Society (IAS). Both Chapters received the “Outstanding Large Chapter” awards for their activities in 2004. He served as the Founding Chair of IEEE Pittsburgh PELS Chapter that received the Best Chapter Award in 2015. Under his Chairmanship, the IEEE Pittsburgh Section received the “Outstanding Large Section” award for its activities in 2005. He received the IEEE Pittsburgh Section Outstanding Volunteer Service Award (2004 and 2023) and PES Outstanding Engineer Award (2004). His other past positions included Editor of the IEEE Transactions on Power Delivery (2002 – 2007), Technical Program Chair of the 2008 PES General Meeting in Pittsburgh, Chapters, and Sections Activities Track Chair of the 2008 IEEE Sections Congress in Quebec City, Canada, PES R2 Representative (2010 – 2011), PELS R1-R3 and R7 Chair (2016 – 2020) and R4-R6 Chair (2021 – 2023), Pittsburgh SSIT Chapter Chair (2018 – 2021) and Member of the IEEE Center for Leadership Excellence (CLE) Committee (2013 – 2014). He is an inaugural class (2013) graduate of the IEEE CLE Volunteer Leadership Training (VOLT) program. He has been serving as the Special Events Chair of the IEEE Pittsburgh Section and Boy Scouts of America Leader for more than a decade. He is a Distinguished Toastmaster (DTM) who led District 13 of Toastmasters International (TI) as its Governor to be the 10^th-ranking District in the world in 2007-8.
