About the programme

The legacy electrical grid infrastructure, built for the electricity transmission and distribution, is aging and incapable of accommodating the profound changes. Flexible ac transmission systems (FACTS) and high voltage direct current (HVDC) transmission systems are increasingly deployed to reinforce the transmission grids interconnecting with large-scale renewable energy sources. New power-electronic-based grid infrastructure, e.g. charging stations for electric vehicles (EVs), solid-state transformers, medium-voltage DC (MVDC) transmissions, power-to-X systems, etc., are also emerging into distribution power networks. This Research Programme intends to develop the next-generation electrical infrastructure for the forthcoming power-electronic-based power systems. On the one hand, the opportunities brought by the emergence of wide-bandgap (SiC and GaN) power semiconductor devices are exploited. Novel hardware topologies of power converters are developed for the power grid infrastructure. On the other hand, the dynamic behaviour of power converters, considering the impacts of miscellaneous control schemes, are also characterized and shaped, in order to address the challenges coming with the proliferation of power electronics apparatus in the future power grids. The electromagnetic compatibility of electronic power grid infrastructure is also focused.
