The challenge in the project DESIGNETZ was how to increase the share of renewable energies in the gross electricity consumption, taking into account all energy sources. Specifically, Fraunhofer IESE provided support in the design of the distributed system architecture of the integrated data and services platform for energy grid management as well as in the elicitation of data privacy requirements and the development of data usage control components for the integrated platform. In addition, it performed smart data analyses for modeling, predicting, and diagnosing flexibility potentials in energy grids, and evaluating the architecture of the SESAM farm demonstrator for the networking of Smart Energy and Smart Farming. The end result was a holistic view of the energy system across all stakeholders and energy sources: Finer control down to the distribution grids was developed, and existing isolated ICT solutions were combined to create a smart, resource-efficient energy supply of the future.
