Accurate wind turbine power curves lay solid foundation for wind turbine performance evaluation and wind power forecasting, and then serve the planning and operating a low carbon energy system including renewables and electric vehicles. In order to improve the model accuracy, this paper presents the concept of quantile power curve and a quantile loss function based neural network algorithm, for establishing the proposed quantile power curve model. Based on the operational data of three wind turbines in a wind farm in China, a case study is carried out to validate the proposed model. The results show that the proposed quantile power curve model has good reliability.
