Analysing Frequency Support from DFIG-based Wind Turbines - Impact of Parameters and Initial Conditions

Enabling the type-III and type-IV wind turbine generators to participate in grid frequency control couples them to the electromechanical modes of the grid. In this paper we have investigated how initial wind speed, rotor-side controller parameters, PLL parameters and pitch angle controller parameters influence the virtual inertial response and primary frequency response of the total power controlled DFIG-based wind turbine generator.
