Exponentially increasing amounts of data and process information are generated in the power system. Due to the advance of automation on lower voltage levels, this applies to both the transmission and distribution grids. At the same time, however, the most relevant data streams for the network, such as voltages, currents and power values, are becoming more and more volatile and difficult to interpret in order to derive decisions for grid planning and system operations. The research focus takes these contradictory developments into account and researches new algorithms and processes for planning the energy transition in the electricity system.
