Load combination forecasting based on power grid with environmental characteristics
Abstract：The characteristics of underground power load in coal mine were analyzed.Based on these characteristics,the appropriate individual forecasting models were selected.It was proposed a combination forecasting method based on combination index induced IOWA operator.In this method,forecasting values of individual model with higher accuracy were substituted for historical data by Dempster synthesize rule.The defect that data are unknown during actual forecasting period was overcome.The concept of equal dimension information was introduced in this model.The forecasting results can be reflected the development law of load by this concept reasonably.Combination forecasting model based on combination index induced IOWA operator is suitable for forecasting underground power load in coal mine.And the forecasting accuracy can be improved.
