For future wide area grids, which are needed to make further offshore wind farms accessible, a reliable and stable multi terminal high voltage direct current (HVDC) grid is proposed. Using HVDC avoids the transfer of large amounts of reactive power related to a conventional high voltage alternating current (HVAC) grid and any onshore AC grids can be efficiently linked together over long distances. This work shows an approach of controlling multiple voltage source converter (VSC) stations using a fictitious, model based machine set for each converter station. The dynamic behaviour of this multi-terminal HVDC system is analysed in simulation.
