Software-driven active customer interface for DER integration

The Nobel Grid project is developing information technology to integrate and fully utilise flexibility potentials of demand response and end-customer operated distributed energy resources (DERs) in the electric energy system. As key part of an according technical solution, the authors develop the 'smart meter extension (SMX)' for rapid development and deployment of new functionalities at end-customer premises. The document at hand reports the project results achieved so far. After summarising their approach, they introduce the Nobel Grid architecture. They then detail the architecture focusing on the SMX. Finally, they show how the SMX can be used to implement two example smart grid functions, highlighting the SMX's capabilities as a modular interface for software-driven DER integration.
