The use of modern, controllable operating equipment can make oversized and expensive grid expansions obsolete while continuing to guarantee the security and reliability of the power supply. The future structure of electricity grids depends a great deal on the equipment that will be connected to the grid in the future and their operation. In our Digital Grid Lab we have tools for optimizing the grid infrastructure which enable us to investigate and visualize various options for strategic network expansion. We offer our customers support in planning the grid of the future.
