"The rapid spread of electric vehicles (EVs) and renewable energy sources is fundamentally transforming the operating logic of distributed energy systems. Microgrid architectures, which integrate solar generation, EV charging and energy storage, are playing an increasingly important role in sustainable energy supply, but at the same time, their management requires complex, competing goals to be managed simultaneously.
The object of my research is the development of such a microgrid energy management system (EMS), with special regard to the integration and gentle operation of second-life Li-ion batteries. The choice of topic is justified by the fact that the simpler rule-based control approaches currently used are not able to take into account grid constraints, electricity market opportunities, EV charging needs and the lifespan of energy storage at the same time. My research aims to eliminate this shortcoming by developing a forward-looking, optimization-based management method, thus contributing to the more efficient and economical operation of microgrid systems."

"The rapid spread of renewable energy sources and the decline of traditional rotary power types are fundamentally transforming the dynamics and operation of the electricity system. Reduced inertia, steeper frequency changes and voltage limit violations are becoming increasingly challenging, while distribution network voltage levels are a bottleneck in the connection of newer generators.
The object of my research is the elaboration of the theoretical and practical concept of multi-frequency virtual oscillator-based control, extending the method to parallel operation on multiple frequencies. The choice of topic is justified by the fact that by consciously injecting harmonic components, the capacity of the basic harmonic component and the network can be increased without increasing the peak value of the voltage. In the course of the research, I investigate the synchronization of network-coupled oscillators and their effect on static and dynamic stability. The theoretical and simulation results will be verified with the help of targeted hardware design and Power Hardware-in-the-Loop laboratory measurements."
