TU Delft and digital-twin company Argaleo have developed a digital twin of the complete electricity network of the TU Delft campus. The model links physical infrastructure to real-time sensor data and brings the energy network together in an integrated 3D environment. This creates a new way to analyze and manage complex electricity networks. Decision-makers can now see the network in real time, test changes, and optimize energy distribution safely before implementing changes in the physical network.
