Description
Summary:Tins paper deals with the integration of large offshore wind farms into the power system. Some main technical issues with regard to the connection of offshore wind farms, such as the HVDC and HVAC transmission systems, the general impact of large scale wind power on the power system operation, and the grid code requirement for wind farms, are reviewed and discussed. The focus of this study is on the dynamic behavior of the offshore wind farms and their interaction with the power system. An offshore wind farm (120 MW), which is made up of doubly fed induction generators (DFIG) and connected to the power system by an HVAC cable, was modeled using the simulation tool PSS©NETOMAC. Based on this offshore wind farm model, the dynamic voltage stability of the test system and its conformity with the grid code requirements on low voltage ride through (LVRT) is investigated by simulating a 3-phase short-circuit fault in the test grid.
