The AGISTIN project’s work on integrating hydrogen into local energy systems was a key component of the 3rd Summer School on Integration of Local Energy Systems, held from August 20th to 22nd. Hosted by the Hamburg University of Applied Sciences (HAW) in collaboration with the Fraunhofer IWES’ Application Center on Integration of Local Energy Systems (ILES), the Summer School took place in the physics laboratory facilities of the HAW Hamburg Campus Bergedorf. 

The event offered a comprehensive and hands-on learning experience, where participants explored topics at the intersection of renewable energy, energy storage, electrolyzers, and advanced control systems. On behalf of the AGISTIN project, the colleague from Fraunhofer IWES, Christoph Kaufmann, introduced the project and provided an overview of converter-control design, Abdul Rafey Asim guided students through key modeling tasks, and Aline Luxa introduced the topic of electrolyzers. 

Participants learned to build models of renewable energy plants, develop control systems, and implement them on real-time digital simulators. This deployment of models on real-time digital simulators allows for testing real hardware with those models, such as the rectifier of an electrolyzer, in a power hardware-in-the-loop setup using grid emulators like the Fraunhofer IWES’ PQ4Wind.  These activities aligned with AGISTIN’s Work Package 5 (WP5), which focuses on demonstrating AGI-integrated innovative storage solutions for green hydrogen production, with the goal of enhancing electrolyzer electrical integration, efficiency, and lifetime. 

In addition to the AGISTIN content, the Summer School also covered some of  fundamentals of renewable energy-based local energy systems, control theory, and the principles of electrolyzers, offering a well-rounded foundation on local energy systems integration.
