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 PhD position available on the subject of modelling of AC/DC underground transmission grids to assess converter-related interactions and design optimal control.
The energy transition requires a strong increase in the transport of electricity at high-voltage level over greater distances. This need cannot be met with the current transmission networks and substantial additional capacity is required, which can only be achieved through the construction of new connections. To make these connections socially acceptable they should be placed underground as much as possible. This need to build underground high-voltage grids will result in 3 changes in the future transmission network:
1. More AC underground cables in the AC network;
2. More DC connections to transport large powers over long distances (underground);
3. The roll-out of a new backbone network, an internal meshed HVDC network that efficiently and reliably integrates distributed energy sources.
However, a major challenge is the control of power electronic converters in systems which contain a large share of AC and DC cables. To provide a solution to this problem, the objectives of this project are:
4. The identification of converter control limitations in transmission grids with high share of underground AC/DC cables.
5. The development of the required control algorithms for HVDC converters to facilitate a high share of underground cables in transmission grids and to enable the efficient operation of these grids.
6. The development of tools and models that allow to integrate multiple HVDC converters of different vendors and assess the impact of grid-forming control
Interested candidates should have a good understanding of modelling and control of power electronics converters. A strong interest and affinity in power system dynamics and simulations is essential.
