基于改进 KNN 算法的风电功率实时预测研究
Wind power real-time prediction research based on the improved KNN algorithm
摘要
Abstract
Integration of large-scale wind power into the power grid will greatly influence grid planning and construc-tion, analysis and control, and energy quality.Accurate short-term wind power forecasting can provide a reliable basis for safety dispatching and stable operation of the power system containing large-scale wind power generating units. This paper studied wind power short-term prediction methods.With the chaos theory as the basis, the parameters for phase space reconstruction were calculated, and a wind power real-time prediction method based on the improved KNN( K-Nearest Neighbor) algorithm was proposed.Multiple evaluation indexes were applied to evaluate the forecast results, and the effectiveness of the model was verified with the measured data of a wind farm in the west of Jilin as the sample.关键词
