With an output of 1 MVA, the "Power Hardware in the Loop" (PHIL) laboratory is the most powerful research facility and a central component of the infrastructure of the "Smart Energy System Simulation and Control Center" (SEnSSiCC), embedded in the project framework of the Energy Lab.
Our goal is to investigate the system integration and control of new types of equipment using real-time simulation technology in combination with real components.
We are focused on three research areas:
-
Power Hardware In the Loop (PHIL): We research the stability and accuracy of a PHIL system to perform stable and accurate evaluation of technologies under realistic conditions.
-
Energy storage systems: We investigate which grid services the storage systems can offer and which technology best suits to solve certain problems (e.g. primary frequency control).
-
Superconducting power devices: We model and test superconducting power components with regard to thermal, electrical and mechanical properties.





At this year's PowerTech conference of the IEEE Power and Energy SocietyFelix Wald from our group presented a new, groundbreaking paper entitled "Applications and Services of Solid-State Transformers in Active Distribution Networks - A Critical Review".
This year's conference, "Powering the Energy System Transformation", addressed the urgent challenges and opportunities associated with the global transition to more sustainable and resilient energy systems.

The Real-Time Simulation workshop brings together experts in power engineering to exchange ideas and create collaboration between universities and research institutions. As an annual event, it offers a valuable opportunity to reconnect with the community and continue building long-term collaborations in the field.
