预测一天的负荷，共预测24个点，间隔为一个小时，将预测的负荷与实际负荷相比较，求出其误差率，将满足要求的模型用于未来负荷预测(The daily load is predicted with a total of 24 points and an interval of one hour. The predicted load is compared with the actual load and its error rate is calculated. The model meeting the requirements is applied to the future load forecast)
