摘要
为给贵州省电力规划提供依据,以便制定科学、合理的发输电规划方案,基于贵州省1985～2009年用电量特点,选取趋势外推法、线性回归法和灰色模型法三种电力负荷预测方法预测了贵州省2015～2020年的用电量,并进行对比分析。结果表明,不同的电力负荷预测方法预测精度不同,灰色系统理论具有很强的通用性。
In order to provide the reference for Guizhou province electric power planning to formulate scientific and proper generation and transmission scheme. Based on the power consumption characteristics of Guizhou province during 1985-2009, this paper forecasts the power consumption of Guizhou province during 2015-2020 by using trend extrapolation method, linear regression method and gray model method, and makes comparative analysis. The results show that different power load forecasting method has different prediction accuracy and gray model method has strong compatibility.
