The Future Distribution Substation from Siemens, with an integrated IoT connection, is Siemens solution for preparing your distribution grid for the challenges of the transition to a new energy mix. The smart secondary substation represents future-viable power distribution. It focuses on digitalization, decarbonization, and decentralization.
Medium- and low-voltage power grids need to handle changes due to the increasing integration of distributed infeed of renewable energy and growing electromobility in private transportation. While more and more of the necessary connection capacity can be provided through grid expansion, the effects of changing energy flow direction, load fluctuations, and voltage range compliance can only be managed with intelligent solutions.
