Abstract

The progression of the energy transition leads to a steady increase of power plant installation that are based on renewable energy sources in Germany. Together with the growing demand for sector coupling and the electrification of end-user applications in fossil-dominated sectors, these transformation processes are causing far-reaching changes in conventional power generation and consumption. To ensure a secure operation of the grid, congestion management plays a key role within the German transmission grid. Today, the flexibility to adjust active and reactive power generation is primarily provided by conventional power plants located at the transmission grid level. In the future, however, it is foreseeable that a large part of the available flexibility options, especially new types of electrical applications, will mainly be located at the distribution grid level. Consequently, the question arises as how the access of these flexibility options by the transmission system operators should be coordinated with local distribution system operators. In the context of this dissertation, different fundamental design concepts are therefore evaluated against each other with respect to operational congestion management. The exemplary investigations show that those concepts are particularly suitable which enable the realization of synergy effects across different voltage levels and can thus contribute to a reduction of the necessary interventions by individual grid operators.
