Aiming at the forecast of reactive power in the power distribution network,this paper selects an appropriate GM (1,1)model,and adopts αparameter modification and residual correction to improve the traditional scale.A series of numerical examples prove that the improved model raises prediction accuracy effectively and is of practical value.%针对配电网中无功数据的预测问题做了研究,选取了合适的GM(1,1)预测模型,并采用了α参数修正、残差修正等方法对传统规模性进行了改进。通过一系列的算例分析,证明了改进后的模型有效的提高了预测的准确度,并具有一定的实用价值。
