User-Defined Pitch Controller and Variable Wind Speed Turbine Aero-Dynamics Model in PSS/E

As a broadly used power system analytical simulation platform in the world, PSS/E has considerable advantage in the research of model simulations. However, the wind turbine generator (WTG) model in PSS/E ignores the variation of wind speed and cannot be used to study the impact of wind power volatility on power system. Based on the principle analysis for the PSS/E 2nd-generation generic wind turbine model, a variable wind speed WTG model is established by using the PSS/E user-defined function in this chapter. The effectiveness and correctness of these models are validated and proved in study cases. The research in this chapter enriches the transient model library in PSS/E and is benefit to the study of the wind generation influence on the operation and stability of the power system.
