Digitechnetz – a smart grid platform enabling an active operation of low voltage distribution grids

The energy transition has resulted in the integration of power-intensive consumers and producers into low voltage grids. This has led to an increased load on these grids, which may reach their capacity limits and thus necessitate grid expansions. However, grid expansions cannot be completed in a short-term period due to various limitations. The project DIGITECHNETZ focuses on the digital transformation of low voltage grids and proposes different use cases for an active grid management. The core component of this project is a data platform that provides essential services for active grid operation. The platform is designed with a modular and hierarchical structure to ensure interoperability and scalability. All use cases are developed and validated using Hardware-in-the-Loop tests. Subsequently, field tests are conducted to seamlessly integrate selected use cases into the operation schemes of grid operators.
