increased loading of power grids
The electrical energy system is under enormous pressure of expectations: on the one hand, it should be the first closed energy system to be completely decarbonised, on the other hand, most probably a considerable additional proportion of final energy consumption will be provided by electricity, for example for transport, heating, and industry. As a result, both the grid expansion and the future higher technical utilisation of the electricity grids will play a role in the overall solution. At the transmission grid level, this has already been taken into account with the development of the first hybrid grid structures in combined AC and DC grids (“embedded HVDC”). In the future, such new network topologies at all voltage levels in conjunction with weather and situation-dependent network operation will change many planning and operating principles and have an impact on both the need for network expansion and the amount of renewable energy that can factually be integrated.
