摘要
介绍了电力系统负荷预测中的回归分析模型法、灰色系统预测法和趋势外推法的原理,对三种单一预测方法的优缺点进行了比较,研究了结合以上三种方法的组合预测法。使用组合预测法避免了单一预测法的局限性,提高了负荷预测的精度,有利于用电管理。
Introduction was made to the principles of regression analysis model,the grey system forecasting and the trend extrapolation in load forecasting of power system.This paper compared advantages and disadvantages of the three single forecasting methods and studied the combination of the three single forecasting methods.Using combination forecasting method can avoid limitations of single forecasting method,making for management of power use.
