Frequency-Domain Stability Engineering for Converter-Based Power Systems
Power systems are entering a new era. Renewable energy, battery energy storage, HVDC transmission, AI data centers, and electric transportation are rapidly increasing the penetration of power-electronic converters. As a result, future power systems will be dominated not by synchronous machines, but by converters interconnected through increasingly complex AC, DC, and hybrid AC/DC networks.
While this transition enables unprecedented flexibility and efficiency, it also introduces new dynamic interactions and stability challenges that cannot be adequately analyzed using traditional power system methods alone. A new engineering framework is needed.
A New Engineering Framework
Frequency-domain stability engineering extends classical stability analysis to converter-based power systems. It provides systematic methods to model dynamic interactions over a broad frequency range, identify instability mechanisms, understand their physical origins, and develop practical engineering solutions.
Frequency-domain methods answer the questions engineers encounter in practice:
Why does instability occur?- Which equipment or control function causes it?
- How do converters interact through the network?
- How can stability be improved through converter control or system design?
- How can stability requirements be specified before equipment is deployed?
The Analytical Foundation
The analytical foundation of this course is immittance-based frequency-domain modeling and analysis. It provides a unified framework to model components and systems, assess stability, identify root causes, design solutions, and develop engineering specifications—applicable across different converter technologies and system architectures.
