About the Webinar: This webinar will provide a summary of all chapters of the CIGRE Green Book on Power System Dynamics Modelling and Analysis in Evolving Networks and then will focus on more detailed presentation of selected topics as follows:

• Introduce the importance of, and the need for, revisiting classical power system stability analysis concepts and textbooks.
• Discuss different classes and sub-classes of power system stability, with a focus on considerations when performing power system dynamic analysis under high inverter-based resource (IBR) penetration scenarios. Practical experiences of various forms of power system instability are also presented.
• Provide discussion of various dynamic modelling approaches including phasor-domain and electromagnetic transient programs and types of power system dynamic simulation software programs ranging from highly detailed to simplified screening. The use of screening methods and the applications of power system dynamic modelling and other tools for operational decision-making are presented in detail.
• Discuss different types of models and the necessary level of detail for each to ensure sufficient accuracy whilst respecting practical limitations. Power system components covered include generation technologies such as synchronous machines and IBR, HVDC systems, loads and distributed energy resources (DER) and wide-area network modelling including protection systems.
• Present dynamic studies typically conducted in power systems with a high penetration of power electronic interfaced devices. Grid interconnection studies for IBRs, HVDC systems, and FACTS controllers, and power system dynamic studies for operational and planning applications are presented. These include assessing and mitigating contemporary electromechanical oscillations and emerging electrical oscillations and control interactions. The impact of protective functions on power system dynamic performance, and studies of industrial power systems and microgrids are also presented.
• Focus on ensuring high-quality, accurate and up-to-date dynamic models for power system plants and the overall system. This spans model acceptance testing during early stages of plant development, to model validation where a mature design has been accomplished, and the plant is already connected and commissioned.
• Recognizing the need to analyze a higher volume of data with higher accuracy and speed for increasingly complex equipment and power system responses, the last part discusses contemporary enablers for power system dynamic analysis. It first discusses artificial intelligence (AI) and machine learning-based methods and cloud-based computing and then introduces the use of probabilistic analysis and optimization techniques and elaborates on the importance of interoperability and standardization.

About the Speakers: Babak Badrzadeh is currently the Managing Director of Etik Energy a consultancy business based in Melbourne, Australia. He has more than 20 years of multi-sector power industry experience including positions at AEMO, Vestas Aurecon, and Mott MacDonald. He has provided consultancy services to many national and international organisations ranging from system operators, network owners, plant owners and developers, policy makers, original equipment manufacturers, and research institutions. He has investigated a wide range of practical power system phenomena, ranging from DC to MHz, and more than 15 different types of generation and load technologies in different countries. His contributions to international organisations include successful completion of three CIGRE Technical Brochures as the Convener, a Special Reporter of SC C4 in 2022 Paris Session, an ongoing Associate Editor of IEEE Power and Energy Society (PES) Magazine, and a distinguished lecturer of IEEE PES. Babak is a Fellow of Engineers Australia, an adjunct Professor at Monash University, a recipient of Energy Systems Integration Group (ESIG) Excellence Award and the Convener of CIGRE Australia C4 Panel on Power System Technical Performance.

Zia Emin received his BSc in Electrical & Electronics Engineering from the Middle East Technical University, Ankara, Turkey and MSc and PhD degrees from The University of Manchester, Manchester, United Kingdom. He has worked as a power system engineer specializing in the planning and development of electric power networks, initially with National Grid and later with Parsons Brinckerhoff (later WSP) and PSC. Since 2023 he is working in Electric Power Research Institute (EPRI) as a technical executive. He has extensive knowledge in all aspects of power system modelling including steady-state, frequency and time domain modelling and substantial experience in harmonic performance specifications of power electronic interfaced devices (HVDC converter stations, FACTS, renewable generation connections etc).

He has been active in many CIGRE (International Council on Large Electric Systems) working groups as member, task force leader and convenor within system technical performance area. He received the CIGRE Technical Committee Award in 2013 and the Distinguished Member award in 2014. From 2016 to 2022 he was the chairman of CIGRE SC C4 and its Strategic Advisory Group. In this role as CIGRE Study Committee Chairman he was responsible for the formation, operation, and deliverables of around 40 highly specialized technical working groups. He was also a member of the CIGRE Technical Council at international level and the past chair at national level (CIGRE-UK). Currently he is a member of the CIGRE Strategic Advisory Board.

He is a Fellow of the Institute of Engineering and Technology (IET – UK), a Senior Member of IEEE, a Distinguished and Honorary Member of CIGRE, a European Engineer, and a Chartered Engineer in the United Kingdom.
