| Abstract |
Estimates are that circa 40GW of offshore wind power capacity is going to be installed throughoutEurope by the end of this decade. In this scenario, a pan-European offshore grid network is needed inorder to efficiently integrate large amounts of offshore wind into the different European countries’transmission networks. In this paper, the dynamic model of multi-terminal HVDC (MTDC)transmission system composed of voltage-source converters is presented. Afterwards, the dynamicmodels are used to compare four different methods for controlling the DC voltage inside MTDCnetworks, viz.: droop control, ratio control, priority control and voltage margin control. Lastly, a casestudy is performed in a four-node MTDC network and the different control strategies are compared. |
