The problem of determination to weighting coefficient is a key and difficulty for combination forecast. The result of the forecast will be straightly influenced if the selection of the weighting coefficient is illogicality. A new method of combination forecasting applied in electric power system is showed in this paper. It is based on the rough sets theory, and the weighting coefficient of all the forecast methods is distributed, so that the calculation of the weighting coefficient will be more impersonal and simple, and the result of the forecast will be more exactly. In this paper, two samples were used to check the accuracy of this method, the Percent of errors were 1.76% and 2.3197%. Compared with another method for combination forecasting- artificial neutral network, the Percent of errors were 16.213% and 35.7084%, respectively
