SUMMARY:Tutorial: From Frequency Scan to Immittance-Based Stability Theory: Frequency-Domain Methods for IBR and Future Power Systems
DESCRIPTION:Download Presentation \nView Webinar Recording \nDownload Q&A Responses \n\n  \nDr. Jian Sun\nFeatured Presenter: Dr. Jian Sun\, Professor in the Department of Electrical\, Computer and Systems Engineering\, Rensselaer Polytechnic Institute (RPI);  Director of the Center for Future Energy Systems (CFES) \nAbout the Tutorial: Frequency scan has been used to identify subsynchronous resonance (SSR) involving generators since 1970’s. The method is intuitive and easy to use but remained for a long time an ad hoc numerical procedure. This changed with the establishment of the small-signal sequence immittance theory of which frequency scan is a simplified application. The more general definition and mathematical development of immittance-based frequency-domain models at both the component and system level as well as stability analysis based on such models opened new applications and provided a general framework to address stability challenges in renewable generation\, HVDC transmission\, and future power systems. This presentation gives an overview of the immittance-based stability theory and its successful application to solve IBR-grid interconnection problems such as high-frequency resonance of HVDC converters\, supersynchronous resonance of wind and PV inverters in weak grids\, as well as various subsynchronous problems. New developments to address system-wide stability concerns of future grids dominated by IBR are also reviewed. \nAbout the Presenter: Dr. Jian Sun joined the faculty at Rensselaer Polytechnic Institute (RPI) in 2002\, where he is currently a Professor in the Department of Electrical\, Computer and Systems Engineering. He is also Director of the Center for Future Energy Systems (CFES) funded by New York State government. His research interests are in the general area of power electronics and energy conversion. He is credited for creating the small-signal sequence immittance theory and promoting its practical applications in different industries for over 15 years. \nDr. Sun received his doctorate from University of Paderborn\, Germany. Prior to joining RPI\, he spent five years at Rockwell Collins working on power electronics for aircraft power systems and was a Post-Doc Fellow at Georgia Tech from 1996 to 1997. As Director of CFES\, he is responsible for the strategic directions and development of the Center’s research\, industry collaboration\, education\, and outreach programs. His professional activities in the power electronics community included serving as Editor-in-Chief of IEEE Power Electronics Letters from 2008 to 2014\, Treasurer of IEEE Power Electronics Society (PELS) from 2013 to 2020\, and as PELS Vice President of Conferences since 2021. \nDr. Sun received the IEEE PELS Modeling and Control Technical Achievements Award in 2013 and the R. David Middlebrook Outstanding Achievement Award in 2017. He is a Fellow of IEEE. \nRegistration Cost: FREE \nQ&A Session: We will be using the slido platform for Q&A.

SUMMARY:Webinar: U.S. Department of Energy's National Transmission Planning Study Results
DESCRIPTION:Download Presentation \nView Webinar Recording \n\n  \nYamit Lavi\nFeatured Speaker: Yamit Lavi\, Technical Advisor\, Grid Deployment Office\, U.S. Department of Energy \nWebinar Abstract: The U.S. Department of Energy recently released the National Transmission Planning (NTP) Study\, a set of long-term planning tools and analyses that examine a wide range of potential future scenarios through 2050 to identify pathways to maintain grid reliability\, increase resilience\, and reduce costs\, while meeting local\, regional\, interregional\, and national interests and supporting the changing energy landscape. This webinar will give an overview of the study which finds that the United States will need to approximately double to triple the 2020 transmission capacity by 2050 to meet demand growth and reliability needs\, and hundreds of billions of dollars of cost savings can be achieved through substantial transmission expansion and interregional planning. \nAbout the Speaker: Yamit Lavi serves as a technical advisor at the U.S. Department of Energy Grid Deployment Office\, where she oversees a portfolio of projects focused on expanding interregional transmission to accelerate decarbonization while ensuring system reliability. She has over a decade of experience in power systems and has previously worked at the Electric Reliability Council of Texas (ERCOT) as an operations engineer. Yamit holds a Ph.D. in Engineering and Public Policy from Carnegie Mellon and a B.S. in Electrical Engineering from The University of Texas at Austin. \nModerator: James Okullo\, Director of System Planning\, ESIG \nRegistration Cost: FREE \nQ&A Session: We will be using the Slido platform for Q&A.

SUMMARY:G-PST/ESIG Webinar: IBR-driven Sub-synchronous Oscillations
DESCRIPTION:Download Presentation \nView Webinar Recording \nDownload Q&A Responses \n\nBalarko Chaudhuri\nFeatured Speaker: Balarko Chaudhuri\, Reader in Power Systems\, Imperial College London \nAbout the Webinar: Increasing shares of inverter-based resources (IBRs) present unprecedented grid stability challenges. One particular concern is sub-synchronous oscillation (SSO) caused by multiple IBRs interacting across the power grid especially\, under high IBR scenarios. The opaqueness of IBR controls and lack of an established framework for analyzing SSO makes it difficult for the system operators to foresee SSO as exemplified by recent SSO events such as poorly damped 8 Hz oscillations in Scotland. System operators often respond by limiting the fraction of IBRs i.e.\, by constraining off renewables in an overly conservative way. This webinar will focus on the IBR-driven SSO problem\, analysis and mitigation based on our ongoing research with the National Energy System Operator (NESO) in Great Britain and as part of the Global Centre on ‘Electric Power Innovation for a Carbon-free Society (EPICS)’. \nAbout the Speaker: Balarko Chaudhuri is a Reader in Power Systems in the Department of Electrical and Electronic Engineering at Imperial College London. His research focuses on dynamic stability and control of electric power grids with high shares of variable renewables and inverter-based resources to facilitate the transition to net zero carbon electricity. \nBalarko serves as the UK Director of the Global Centre on Electric Power Innovation for a Carbon-free Society (EPICS) and is actively involved the Stability Assurance Program supported by the National Energy System Operator (NESO) in Great Britain. He co-leads the workforce development pillar of the Global Power System Transformation (G-PST) consortium where he coordinated the G-PST Teaching Agenda and oversees the development of openly available course materials on ‘forward-looking’ topics for use in teaching\, training and self-upskilling. Balarko is a Fellow of the IET and has served as an associate editor of IEEE Transactions on Smart Grid\, IEEE Systems Journal\, and Elsevier Control Engineering Practice. \nModerator: Julia Matevosyan\, Chief Engineer\, ESIG \nRegistration Cost: FREE \nQ&A Session: We will be using the slido platform for Q&A.
