Impact of the VSC HVDC Connection of Large Offshore Wind Farms on Power System Stability and Control

Abstract

The impact of the wind power on the power system stability and control is already notable. With the increase of their power (single offshore wind farms will reach over 1000 MW) their impact will increase too. In this paper the use of voltage source converter HVDC transmission technology for the connection of the large offshore wind farms to the power system will be presented. The modelling of VSC HVDC and its control parameters and loops has been detailed. The impact of such connection on the power system stability and control has been analysed on a test power system.
