SUMMARY:Webinar: Analysis of IBR-driven Oscillations in the Australian Grid
DESCRIPTION:Download Presentation \nView Webinar Recording \n\n  \nFeatured Speakers: Nilesh Modi\, Manager of Future System Studies team\, Australia Energy Market Operator (AEMO); Shahil Shah\, Principal Engineer at the Power Systems Engineering Center\, National Renewable Energy Laboratory (NREL) \nWebinar Abstract: The widespread integration of inverter-based resources (IBRs) has led to increasing instances of oscillations in power systems\, driven by factors such as control interactions among IBRs and low system strength. In particular\, sub-synchronous oscillations have been observed in regions of the Australian grid with high concentrations of IBRs. When such oscillations spread across a large portion of the network\, it becomes crucial to identify their root causes to enable both operational mitigation and the exploration of long-term solutions. \nThis webinar will review recent IBR-driven oscillation events in the Australian grid and the proactive steps taken by the Australian Energy Market Operator (AEMO) to investigate these occurrences. A central focus will be the analysis of 17-20 Hz oscillation events\, learnings from real-time observations\, and analysis of these oscillations using electromagnetic transient (EMT) simulation and impedance scan studies. \nKey takeaways will include: \n\nEMT and Impedance-Based Analysis: Insights into the application of impedance scans of IBRs and the transmission network\, leveraging electromagnetic transient (EMT) simulation models to identify system resonance modes.\nDamping Contribution Assessment: Evaluation of the positive or negative damping contributions from individual IBRs to these modes.\nEnhancing System Strength: Demonstrating the role of grid-forming resources in improving system strength and reducing the risk of oscillations\, quantified through frequency scan testing.\n\nThis webinar will provide actionable insights into using advanced approaches such as impedance-based assessment to address challenges posed by the widespread adoption of IBRs\, offering both immediate and strategic solutions to enhance grid stability. \nAbout the Speakers:\nNilesh Modi is the Manager of Future System Studies team at Australia Energy Market Operator (AEMO)\, Australia. Nilesh has seventeen years of experience spanning across academia\, research and industry. His current area of interest is power system operation with high share of inverter-based resources. Since 2012\, Nilesh has been working at AEMO where he has been involved in various key projects/documents published by AEMO\, namely review of the South Australian (SA) system black event\, system strength requirements\, inertia requirement methodology and large scale EMT modelling of the grid\, and assessment of converter-driven oscillations in IBR rich area. \nNilesh received his PhD from the University of Queensland\, where he was awarded the Dean’s Excellence Award for RHD Excellence. He is a recipient of Energy Systems Integration Group (ESIG) Excellence Award. He is also an Adjunct Senior Research Fellow at the University of Queensland\, Australia\, an active member of CIGRE\, Senior member of the IEEE and Fellow of Engineers Australia. Nilesh is an IEEE PES Distinguished Lecturer. \nShahil Shah is a Principal Engineer at the Power Systems Engineering Center of the National Renewable Energy Laboratory (NREL) in Golden\, CO. His research focuses on the stability of power systems with high levels of inverter-based resources (IBRs)\, with a specific emphasis on impedance-based frequency scan methods for stability analysis. Shahil led the development of the Grid Impedance Scan Tool (GIST) at NREL\, an advanced platform for performing impedance-based stability analysis using both simulation models and actual hardware\, including inverters and wind turbines. GIST was a finalist for the 2023 R&D 100 Awards and has been applied globally in several NREL-led partnerships. \nIn 2022\, Dr. Shah received the ESIG Excellence Award for his leadership in the design and analysis of grid-forming inverter systems. He holds a Ph.D. in Electrical Engineering from Rensselaer Polytechnic Institute (RPI)\, Troy\, NY\, awarded in 2018. \nModerator: Julia Matevosyan\, Associate Director\, Chief Engineer\, ESIG \nRegistration Cost: FREE \nQ&A Session:We will be using the Slido platform for Q&A.
