With the development of smart grids, the focus is increasingly on information and communication technology platforms and services for smart districts, among other things. A key question is: How can existing and newly acquired information on energy generation and use be used effectively to ensure the safe operation of energy grids in particular? The term “safety” refers to both natural and technical failures (safety) as well as targeted attacks from outside (security). In addition, the collection of prosumer data enables new innovative distribution management concepts, which can help to prevent large-scale blackouts in times of grid bottlenecks.
