New developments and innovative technologies require acceptance testing before being integrated into existing systems. A testing environment that provides realistic settings and component interactions ensures optimal feedback and insights for developers and manufacturers. The laboratory facilities of the Fraunhofer Center Digital Energy enable integration and testing across multiple technologies and OEMs. This allows for practical testing, inspections, and trial runs without risking adverse effects within the public energy supply system.

The available laboratory equipment represents a quasi-real image of the energy infrastructure of current and future power grid operators (primary, secondary, control room, information and communication technology). Close cooperation with the Institute for High Voltage Equipment and Grids, Digitalization and Energy Economics (IAEW) at RWTH Aachen University ensures extensive and directly operational research infrastructure for measuring, simulating, certifying, and testing energy technology components and systems for research projects.

Within the Fraunhofer Center for Digital Energy, this environment enables both application-oriented research and development as well as independent testing and verification going beyond current approaches. IT security tools, penetration tests, patches, network technologies and novel concepts can be tested (such as data spaces, SSI, quantum communication, blockchain, or high-performance computing) directly within an operational system, prior to actual implementation within the energy supply infrastructure. 


Modern testing facilities allow for detailed examinations of primary, secondary, and information technologies in critical infrastructures.

User Stories


Control Room

Regular training courses are necessary to adequately prepare control center personnel for the challenges of network operation management and to ensure smooth operations. Critical scenarios can be created for learning purposes, much like a »flight simulator«.


Cyber-Physical Systems

For the development of digitalization solutions in the energy sector, having access to a realistic laboratory environment is essential. This allows new technologies and configurations to be examined safely and efficiently. It enables the evaluation of their impact on the entire system in advance.


Power Quality

The Center for Digital Energy investigates both the origin and the detection of power quality problems in order to maintain the quality of the energy supply at a high level in the long term.


Cyber Security

The Digital Energy Research Center is dedicated to using cyber-physical laboratory environments combined with advanced co-simulation techniques for conducting IT security investigations in the energy sector. The aim is to develop, test, and validate innovative cybersecurity solutions.


Distribution Grid Dynamics

Innovative operating and control concepts for future distribution grids can be investigated in a practical manner in the distribution grid laboratory at the Center for Digital Energy.


Grid Protection Concepts

In collaboration with RWTH Aachen University, the Fraunhofer Center Digital Energy offers the opportunity to examine and evaluate innovative grid protection concepts throughout their entire process chain in the protection laboratory.


Smart Home

The share of decentralized energy generation in the distribution network is steadily increasing. A large amount of smaller scale generation units are connected witihn private homes and businesses (behind-the-meter).


Certification of Generation Units

In cooperation with the RWTH and an accredited testing laboratory, the Digital Energy Centre offers certification of generation systems in accordance with grid connection regulations.
