Converter Topologies for HVDC Grids

• HVDC grids have significant benefits and will likely play an important role in the future energy system. However, protection and fault handling aspects will be different from those of current ac transmission grids and point-to-point HVDC connections. Therefore, new power electronic solutions will be required. Different fault handling strategies are being discussed and the required converter hardware to implement these is identified. Also different converter topologies with the needed properties, mainly dc-side short-circuit handling capability, are described and compared.
