Master's Thesis - Stability and Oscillation Phenomena in Inverter-Based Power Systems

Fraunhofer IEE in Kassel conducts research in the fields of energy economics and energy system technology, focusing on: energy informatics, energy meteorology and geographic information systems, energy economics and system design, energy process engineering and storage, network planning and operation, grid stability and converter technology, as well as thermal energy technology. Around 450 scientists, employees, and students develop solutions for the energy transition and generate around EUR 38 million in revenue per year.

Research Group: Grid Control and Grid DynamicsThe dynamic behavior of power systems with high shares of inverter-based resources (IBRs) is strongly influenced by converter controls and their interaction with the surrounding network. These interactions can give rise to oscillatory modes, adverse coupling between devices, and stability limitations that depend on both converter characteristics and system conditions. The Grid Control and Grid Dynamics research group at Fraunhofer IEE investigates these phenomena using analytical methods, numerical simulations, and models at different levels of complexity.
