The Smart Grid LAB in Hesse – Active Maximization of Annual Us-age Time of Electrical Grids Using Flexibilities while Ensuring Data Security and Resilience at the Same Time

Renewable based energy systems are electricity focused and employ mostly non-controllable and dispersed energy sources. Compared to conventional, controllable steam or gas turbines they are much more dynamic. This causes two challenges. First, the new electrical system has significantly higher, volatile, and intermittent power. Under this premise the balance between production and consumption must be kept at any time. The second technical challenge is to bridge the spatial gap between permanently varying local surplus and lack of energy. These two challenges request the application of digitalisation tools. Data and information are becoming key. The system becomes smart and multimodal, which means the concerted use of different final energies. In this context also electrical grids are transformed into smart grids. The internet of things (IoT) penetrates the electrical infrastructure. Sensors, data transmission, data processing and actuators allow a much more efficient use of the existing infrastructure. Operational technology (OT) and informational tech-nology (IT) are converging. Up until now the focus of most smart grid projects was put on data processing and algorithms. The Smart Gird LAB Hesse goes further. A real low voltage smart grid for the street of the future with customi-zable prosumers including all IT- and OT-components is built, and an appropriate control algorithm implemented. The impact of non-authorized data and information misuse is analysed and relevant strategies for data and information security are developed. The future oriented concept of “smartness” must not create new risks for the security of supply.
