Within the Electrical Energy & Computer Architectures (Electa) research division and EnergyVille, the research team led by prof. Jef Beerten focuses on the combined modelling and control of power electronic converters and power systems, with a focus on DC systems. The group of PhD students and postdocs consists of about people. Within the team, we have a research associate position available on the subject of modelling and stability analysis of future converter-based power systems.
The massive integration of renewable energy sources in the power system worldwide is pushing the transmission systems to their limits. Power electronics-based network components are playing a major role in this energy transition. They offer the possibility to control power flows and increase the reliability of the network under variable working conditions. On the transmission level, High Voltage Direct Current (HVDC) technology is the candidate for reinforcing and upgrading the system. Long-term visions encompass rolling-out an offshore grid in the North Sea combined with so-called "electricity highways", energy corridors with power ratings that are an order of magnitude higher than existing line ratings.
Despite their advantages, converters can get unstable when the network conditions change, as a certain control loop (e.g., the phase-locked loop or the voltage controller) might adversely interact with other converter controllers in the system, or the non-passive behaviour of converters might result in the excitation of transmission network resonances. With the increasing penetration of power electronic converters in the power system, it becomes crucial to carry out detailed system studies to ensure that the converters do not result in system instability. These detailed system studies require accurate component models representing the dynamic response of the converter hardware and its controllers.
Within the team we have a research associate position available to aid the ongoing and upcoming industrial research projects from the aspect of modelling and stability analysis. The projects deal with realistic transmission system problems related to power electronic converters, and will require extensive model development of multiple test cases. In addition to the modelling work, several controller design approaches will be investigated, and stability studies will be carried out to ensure that the operation of the power electronic converters do not result in any instabilities.
Interested candidates should have a good understanding of power electronics control and stability. A strong interest and affinity in power system dynamics and simulations is essential.
