Abstract

Through the analysis of wind power, reasonably adjusting the power is the key to stable operation of wind power generation. In this paper, first the wind power curve is studied on the basis of the least square method, so that the variation rules of wind power can be determined, and on the basis of a given reasonable threshold, the outliers and abnormal coefficient can be identified.secondly, we expand the data dimension and calculating the 15-day average of every time . Thus there is a new data set , and using the same method above can quickly locate the outliers existing range. Finally, time series iteration method is used to establish outliers identification model, and the points of wind power are found. Finally, the actual value on the abnormal point based on the outlier fitting model is estimated. Thus effective regulation of wind power can be achieved.
