Inertial And Primary Frequency Response Model Of Variable-Speed Wind Turbines
Increase of converter-connected renewable power generation such as variable-speed wind turbines (VSWTs) decreases the system inertia constant which in turn reduces the frequency stability of the power system. Thus, it will be necessary to include these renewables in the inertial response and primary frequency control of future power systems. In this paper, the participation of VSWTs in frequency support is studied. First, the importance of inertial response and primary frequency control is discussed. Then, the linearized model of VSWT with inertial and primary frequency response capabilities is presented and compared against the nonlinear model. Finally, this model is integrated in a system frequency response model that consists of various power plants. Different operational scenarios are simulated to investigate the impact of wind turbines with and without emulated inertia and primary frequency response on frequency stability.
