"Technical Requirements for DER Integration Architectures"
ICT and the integration of DER are two of the most important parts of the future smart grid, so it is necessary to analyse their interaction. In that context, standardization plays a key role to cope with interoperability issues and to develop a sustainable solution.
Internationally, IEC 61850 has been named one of the most prominent standards by most roadmaps, e.g., CEN/CNELEC/ETSI, IEC, IEEE P2030, NIST and Strong and Smart Grid China. The overall focus of the standard family lies on substation automation and the corresponding communication. However, it has outgrown its original purpose with the part 7-420 dealing with the integration of DER into the power distribution grid. Since smart grids are highly complex systems consisting of various actors and components, the IEC 61850 has to be seen in context with other standards in the overall infrastructure.
Within the IEC Seamless Integration Reference Architecture, the importance and interoperability issues become clear. Certain parts for combining IEC 61850-based single DER towards Virtual Power Plants must be addressed (see Fig. 1). Within our talk and contribution, we want to outline the way on how to deal with the existing IEC 61850-model, provide profiles for services, functions and data models for testing purposes, outline the need for a plug & automate paradigm in the smart grid, and provide solutions for integrations with other standards like the IEC 61970 Common Information Model.
