Load Forecasting Based on Rough Set of Weather Factors
Zhang Hong-gang · 2004
Weather condition has an increasing influence upon the power load.How to forecast the weather load is an important research subject.In this paper,first Rough Set was employed to process attribute reduction on weather factors that will influence power load;this procedure can find the essential factors in power load.Then these essential factors were used as coordinates to find the nearest historical data as input for time series model.The method can avoid the subjectivity of traditional forecasting methods.It scales the match procedure of historical data so that it's easy to be applied to software realization.The forecasting error is decreased.The method is applicable to power load forecasting.
