Aggregated control of VSC HVDC systems and offshore wind farms
2013 IEEE Power & Energy Society General Meeting, 2013 This paper discusses the aggregated active power control in a Voltage Source Converter High Voltage Direct Current(VSC HVDC) system, interconnecting one offshore wind farm and two asynchronous onshore grids. Existing control strategies have all been developed for point-to-point connections and need a revision when an operation with more than two ...
