The Smart Operator is a module the size of a paperback book, comparable to a small computer. It is installed in local substations and collects all essential data from the low-voltage grid that the households are also connected to: how much electricity is currently available? How much demand is there? Are storage capacities available, like batteries or an electric vehicle connected to a charging point? How much load can photovoltaic panels on the roof supply?
Energy used to flow in one direction only. The electricity generated in power stations flowed down a one-way street through the grids to consumers. With the transformation of the energy sector there is now an increasing volume of “oncoming traffic”. More and more households do not just consume electricity, they also produce it. A photovoltaic system on the roof or a micro-cogeneration plant in the cellar makes this possible. The growing share of decentralised power generation from renewable energy sources requires the grids to be adapted and expanded. Because the electricity yield from wind and solar energy is changeable and cannot be planned precisely. Electricity grids thus need to become more flexible in order to remain stable despite those fluctuations.
