The increase in wind generation connected to power systems has caused changes in the power system characteristics. This increase has raised a concern related to the system frequency response after a disturbance, since the wind turbine generators do not present an inherent inertia response. As a result, different system operators around the world require a synthetic inertia from wind farms (WF). In this work, an analysis of the frequency support performed by wind farms, composed of doubly fed induction generators (DFIG) wind turbines, is performed. Simulations are carried out in ANATEM, a CEPEL software, using a modified version of the Western System Coordinating Council (WSCC) test power system. The simulations comprise different operating conditions and allows evaluating the wind farm contribution to improve the system frequency after a disturbance. |
