两种风速短临预报方法对比研究
Short-term wind speed forecasting study based on two methods
摘要
Abstract
There two groups of experinents of 10-seceond's magnitude and 15-minute's magnitude wind speed short-term forecasting have been done by using BP neural network method and least square regression method on 4 stations with different topography.The study found that both magnitude of 10-seceond and 15-minute forecasting experiments show:①The method of least square regression is better than BP neural network for 01# and 04# station with larger wind speed.The error is less and forecast satisfaction ratio is larger of least square regression method than that of BP neural network.②For 02# and 03# station with smaller wind speed,the forecast effect is similar between these two methods.In other words,there is no advantage of BP neural network method,which with complex algorithm,in very short-term wind speed forecasting,such as magnitude of 10-second or 15-minute forecasting.Therefore,the algorithm characteristics,the topography,geomorphologieal,climatic characteristics and period of validity should be full consideration,and the comparison test of forecasting should be performed before the method be selected.关键词
