Impact of Wind Power Plants on Power System Dynamic Performance

The dynamics of individual WTGs and the entire wind farms could have a significant impact on the stability of the bulk power system

Rotor angle stability” is not an issue with wind power plants because most WTGs are asynchronous units

No equivalent concept of “rotor angle” or synchronizing and damping torques for such generators

Some studies have revealed that bulk power system “transient rotor-angle stability” is improved if wind power plants, as compared to conventional power plants with synchronous generators, are added at the same location

with WTGs, a smooth and non-oscillatory power delivery is re-established following a disturbance
