This paper investigates the stability and control of offshore wind farms employing medium-voltage ac collection and high-voltage dc (HVDC) transmission to the onshore power grids. Type-IV (full power conversion) turbines and HVDC rectifier based on voltage-source converters are assumed. Output impedance models of the wind turbines and input impedance models of the HVDC rectifier in the positive- and negative-sequence are developed using the harmonic linearization method. An impedance-based… CONTINUE READING
