Decentralized converter controller for multiterminal HVDC grids
Paper i proceeding, 2013

Multiterminal High Voltage Direct Current (MTDC) grids based on Voltage Source Converters (VSC) are considered ideal for the future integration of large scale and highly distributed renewable power generation, as well as interconnection of remote power systems. The control of such grids is challenging as it is necessary to provide accurate power flow control and multiple voltage controlling stations. Existing control techniques either fail to fulfill those requirements or achieve them at a cost of maintaining a communication channel between the local station controllers and a master central control level. This paper suggests a decentralized controller for MTDC grids that ensures accurate power flow control, provides voltage control capabilities to all stations and requires no need for communication between the stations. The validity of the controller was tested in a five-terminal MTDC model proving its functionality.
