Advanced grid-forming converters

The Grid-Forming (GFM) control method for power converters has become a recurring topic among industry engineers, researchers and PhD students working with active power networks and power electronics. The GFM control concept is inspired by the operation of a synchronous power system, particularly how an electromechanical synchronous generator interacts with the electrical grid. Therefore, the GFM approach involves emulating such a physical interaction within the control system of a power converter, which doesn't mean simply replicating every single aspect of a conventional electromechanical synchronous generator in the converter's control system.

The physical approach to the GFM concept has enabled the integration of traditional power system stability control techniques into the power conversion dominion. This step is crucial for enhancing the operation and control of active power systems with high renewable penetration, FACTS/HVDC systems, electric vehicle fleets, stationary storage systems, and large electrolyzers—all them managed by power electronic-based converters. In these systems, new phenomena and interactions between power converters and the electrical grid can compromise the stability and reliability of the system if not properly addressed.

During this 3-day course, we will learn about GFM power converters control, introducing operational principles and control loops, and discussing preferred implementations. We'll review the services that GFM converters can offer to the electrical grid and see what system operators have to say about them. We will explore the complex areas of dynamic and transient stability analysis of GFM converters, providing practical examples. Ultimately, this course aims to equip industry engineers and PhD students with the conceptual and analytical tools necessary to advance their research and industrial developments in the field of GFM converters.

Additionally, this course offers attendees the opportunity to discuss ideas and proposals with experienced instructors, some of whom are pioneers of the GFM concept for power converters. Participants will learn from their field experience and discuss new trends, requirements, and opportunities in the GFM converter sector.

Form of evaluation

PhD students interested in earning a 3 ECTS certificate from Aalborg University are required to submit a report following the course. This report should demonstrate their ability to solve fundamental issues related to the modeling and control of GFM. Students must prepare a brief project report on a specific use case provided by the instructors, showcasing their proposed solutions. The instructors will review and grade these reports to determine eligibility for the 3 ECTS certificate.
