| Abstract |
Estimates are that circa 40 GW of offshore wind power capacity is going to be installed throughout Europe by the end of this decade. In this scenario, a pan-European offshore grid network is needed in order to efficiently integrate large amounts of offshore wind into the different European countries’ transmission networks. In this paper, the dynamic model
of a multi-terminal HVDC (MTDC) transmission system composed of voltage-source converters is presented. Afterwards, the dynamic models are used to compare four different methods for controlling the DC voltage inside MTDC networks,
viz.: droop control, ratio control, priority control and voltage margin method. Lastly, a case study is performed in a fournode MTDC network and the different control strategies are compared during steady-state and an onshore three-phase fault. |
