Decentralized Flexibility Options

The increasing decentralized and renewable energy supply is leading to a growing need for new flexibility options. As a result, players such as energy suppliers and aggregators are faced with the challenge of making millions of new energy systems scalable, secure, and reliable
accessible via modern communication technologies. This requires innovative plug & play-capable approaches based on the latest IT technologies, which also guarantee the requirements of resilient data transmission.

As an interdisciplinary team, we offer our support in connecting and using the various flexibility options. Our services range from technical and conceptual consulting to prototype applications as well as our operational software EnergyConnect, the modern virtual power plant.



Our areas of expertise

  • Secure and reliable system communication, including through the use of intelligent metering systems (iMSys) and the associated smart meter gateway (SMGW) as required by the German Digitalization Restart Act (GNDEW).
  • Measures to increase resilience, including the detection of incidents, in order to meet the increased security requirements in accordance with European (NIS 2), national (BSIG, IT-SiG 3.0) and industry-specific (B3S) regulations.
  • Virtual power plant technologies to demonstrate the provision of system services (including control reserve, redispatch) with renewable generators and flexible storage or load facilities. In this context, we are actively working on the further development of IT and pre-qualification requirements in the control reserve for an increasingly small-scale, decentralized energy market.
  • As an innovator, we combine our expertise in information and communication technologies with the concept of the energy data spaces for interoperable and standardized cross-company data exchange within the energy sector.

DIN EN ISO/IEC 27001 certification

The secure and efficient handling of critical data and secure information systems is of great importance here at Fraunhofer IEE. Therefore, we have had an information security management system (ISMS) certified for various business areas. The focus here is on efficient risk management and the continuous improvement of information security in order to be prepared, for example, for possible cyber-attacks and IT emergencies. The functionality of our ISMS is regularly reviewed in external audits by independent third parties.
