The aim of the project is to develop a dynamic model for a combined electricity/H2 infrastructure in Thuringia and to use various grid operation scenarios to validate how the necessary flexibilization can be implemented technically, organizationally and in terms of energy law against the backdrop of national decarbonization targets.can be implemented technically, organizationally and in terms of energy law. In addition to statements on necessary regulatory adjustments, the result is the development of a combined operational management concept for interconnected and island operation as well as grid reconstruction, including recommendations for implementation.
