摘要

考虑春节对不同行业的影响，提出了一种考虑春节因素影响的月度售电量预测结果修正方法，首先利用历史春节日期距1—3月第一天的天数和历史各行业1—3月的售电量占第一季度售电量的占季比进行曲线拟合，然后利用预测年份春节日期距1—3月第一天的天数和拟合函数计算预测年份1—3月售电量占季比的预测值，最后利用各月占季比预测值对国家电网公司1—3月的售电量预测结果进行修正，得到春节因素修正后的售电量预测结果。实证研究结果表明，本文提出的售电量预测结果修正方法能够有效地降低第一季度售电量预测误差。

Abstract

The effects of Spring Festival on electricity sales of different trades were considered and an adjustment method for electricity sales forecasting result was proposed.Firstly

the month-quarter ratio of historical electricity sales in each trade of every month in the first quarter and the distance between Spring Festival and the first day of every month in the first quarter was used to create a functional relationship.Then

the distance between Spring Festival and the first day of every month in the first quarter of the target year was used as input and the predicted month-quarter ratio of electricity sales of each trade of every month in the first quarter of the target year was calculated according to the functional relationship.The adjusted electricity sales forecasting result can then be computed by using the predicted month-quarter ratio and the electricity sales forecasting of each trade of every month in the first quarter of the target year before adjustment.The adjustment result shows that the proposed method can effectively lower the error of electricity sales forecasting in the first quarter.
