Statistical Method For Energy Loss During Wind Power Curtailment Based On Nacelle Anemometry Data

To assess the energy loss of wind farm during wind power curtailment accurately, a statistical method based on nacelle mast data is proposed. Based on output power of wind power generating unit under normal operation and wind data measured by sample turbine nacelle anemometers, an artificial neural network (ANN) model is established, and using the established model to the time-interval of wind power curtailment, the theory power of wind farm and the energy loss due to wind power curtailment are calculated. And then wind power curtailment is available. The proposed method has the properties of simple principle and good applicability, which has good practical values for engineering application.
