The load forecasting plays a most important role in the safe operation of the power grid. A bigger error in forecasting will bring huge risk to the power grid company in both long and short terms, so the precision of the load forecasting should be improved and the error reduced. The combined forecasting can improve the forecasting precision effectively, however, its weight is relatively difficult to set. Applying the Shapley value method, the weight of every member can be determined according to the distributed error. The calculation example shows that the combined forecasting model determined by the Shapley value method can dramatically reduce the forecasting error.
