The massive integration of wind power using power converters imposed several challenges to the future power system. One of them is related to the decoupling effect of new power sources from the AC power grid, incapacitating a natural frequency response. This situation negatively affects the system frequency response. The aim of this paper is to evaluate the inertial frequency support provided by variable speed wind generators. Time domain simulations of a test system are used for an evaluation of the inertial response provided by the wind turbines. Two major contributions of this paper are: (i) to highlight the positive effect of the inertial response on the system frequency response considering different load variation conditions; and (ii) to practically identify a limit of the synthetic inertia parameter, beyond that the wind turbine stalls negatively affecting the power system.
