This special technical seminar will be held at the workshop venue, the Pestana Douro Riverside.

Please come to the main registration desk to collect your conference badge before going to the seminar.

Modern power systems are increasingly dominated by power-electronic converters. Renewable energy plants, HVDC transmission, battery energy storage, and, more recently, AI data centers are introducing dynamic interactions that extend well beyond the electromechanical phenomena traditionally considered in power system stability studies. Understanding these interactions has become an essential engineering challenge for the design, integration, and operation of converter-based power systems.

This special technical seminar introduces frequency-domain stability engineering—a systematic framework for modeling, analyzing, and understanding dynamic interactions in converter-based power systems. Through representative examples drawn from industrial applications, the seminar illustrates how frequency-domain methods provide physical insight into oscillatory behavior, identify the root causes of instability, and support the development of practical engineering solutions.

The seminar will cover:

• Fundamental concepts of frequency-domain modeling and immittance-based analysis
• How the methodology can be applied to emerging converter-dominated and hybrid AC/DC power systems
• Representative applications in renewable energy, HVDC transmission, and AI data center power systems

The seminar also provides an introduction to the professional training course Frequency-Domain Stability Engineering for Converter-Based Power Systems. Participants will learn how the full course expands these concepts into a comprehensive engineering methodology through detailed lectures, practical examples, and industrial case studies.

The seminar is intended for engineers, researchers, consultants, equipment manufacturers, utilities, system operators, and graduate students interested in the stability of modern converter-based power systems. While prior knowledge of frequency-domain methods is not required, participants should have a basic background in power electronics or electric power systems.

Whether you are encountering converter-driven oscillations in renewable energy systems, integrating new converter technologies into the grid, or simply seeking a deeper understanding of modern power system dynamics, this seminar offers an opportunity to learn the engineering principles behind frequency-domain stability analysis and explore a methodology that has been developed and validated through more than two decades of industrial and academic experience.

• This Special Technical Seminar is not included in the general participation fee of the Wind & Solar Integration Workshop.
• The registration fee is 95.00 € (incl. 23% VAT).
• The registration fee covers the cost of lunch and coffee break.

Dr. Jian Sun has more than two decades of experience in the modeling, analysis, and control of power-electronic systems. His research focuses on understanding dynamic interactions in converter-based power systems and developing practical engineering methods for stability analysis and system design.

He is widely recognized for pioneering immittance-based frequency-domain methods, which have evolved into a comprehensive framework for modeling, analyzing, and designing converter-based power systems.

Unlike analytical methods developed primarily from simulation or theoretical studies, these methods have been continuously refined through direct involvement in solving real-world stability problems for equipment manufacturers, utilities, technology companies, and system operators.

Dr. Sun is also the instructor of the online training course Frequency-Domain Stability Engineering for Converter-Based Power Systems.
