The Swedish electricity grid is undergoing rapid transformation driven by the integration of distributed energy resources (DERs), electrification of transport and buildings, and increasing operational uncertainty. To support efficient and reliable grid operations, distribution system operators (DSOs) require advanced digital tools that can capture the dynamic behavior of real networks, assess grid conditions in near real time, and evaluate the impact of new technologies.
This project aims to develop a high-fidelity digital twin of a distribution grid, combining physics-based modeling, data analytics, and simulation techniques. The digital twin will integrate real operational data from low-voltage and medium-voltage networks, enabling improved situational awareness, flexibility assessment, and planning support. The project is funded by Swedish Energy Agency, in collaboration with E.ON.
