50Hertz operates the extra-high-voltage grid in the north-eastern part of Germany, reliably supplying around 18 million people. The electrical circuits of this grid, with voltage levels of 150 kV, 220 kV and 380 kV, cover a total distance of over 10,000 km. Over 1,000 employees take care of the required expansion of the transmission grid and the management of the electricity system in Berlin, Brandenburg, Hamburg, Mecklenburg-Western Pomerania, Saxony, Saxony-Anhalt and Thuringia. As transmission system operator active in the Central European market, 50Hertz is responsible for the secure integration of renewable energy, the development of the European electricity market and for guaranteeing the security of supply. 50Hertz has currently integrated a share of over 50 per cent of volatile renewable energy into the transmission system and is therefore a world leader in the system integration of renewables.

Short description of the project contribution

Innovative Process Platform

50Hertz conceptualises, develops and operates the ‘Innovative Process Platform’ with the higher purpose of creating decentralised flexibility through small-scale conventional and renewable generating units or switchable and shiftable loads while also studying how they can be used to support the grids and systems. This involves the following challenges:

  • Enabling the integration of decentralised flexibility in the processes for grid congestion management.
  • Further development of the operating reserve processes so that the particularities of virtual power plants or aggregators can be taken into account and, as such, to make the operating reserve market more accessible to these new providers.
  • Improvement of the forecast methods for solar power, especially by processing smart meter data from installations with corresponding private consumption.

All these subtasks present questions that can only be answered in coordination between various players. In addition to the close cooperation with the WindNODE partners, we therefore also collaborate with other associated partners.
