基于优化FCM聚类的RELM风速预测
Wind Speed Forecasting of Regularized ELM Based on Optimized FCM Clustering
摘要
Abstract
Accurate wind speed forecasting is of great significance for large-scale wind power integration. In this paper, a new method of short-term wind speed forecasting is put forward based on regularized extreme learning machine (ELM) of optimal clustering and mutual information attribute reduction. Firstly, considering different effects of different attributes on wind speed, mutual information between wind speed characteristic sequence and wind speed sequence are calculated. The attribute features are selected with maximum- correlation minimum-redundancy algorithm. Then, wind samples are clustered with optimized fuzzy C-means (FCM) clustering method. The ELM is optimized and a combined forecasting model of wind speed is constructed. Finally, wind speed prediction experiment is carried out combined with measured data of wind farm. Results show that the method has high prediction accuracy.关键词
