Abstract:

Abstract:The higher prediction accuracy is,the more helpful is to improve the availability of facilities and the validity of economic dispatches.
Through the load characteristics analysis of Huaiyin area in 2013,the effects of load characteristics and different data pre processing methods are analyzed.The results show that stabilizing the abnormal data is the most directive and efficient method.The original data of daily amount of samples had little effect on the predicted results.The prediction accuracy will be improved greatly when the load forecasting of the working days after major holidays is predicted by deleting the original data in the weekends and major holidays Adjustment of data sequence of the same day types can also be appropriate to increase the prediction accuracy when load is stable in spring and autumn.
