| 摘 要： | 利用灰色理论中累加生成方法能够削弱负荷中随机成分的特点，以及人工神经网络可以逼近任意函数的能力，对具有任意变化规律的数据序列进行拟合和预测．实验结果表明，基于灰色理论和神经网络的最优组合模型的平均相对误差为1．307％，比BP神经网络预测和灰色理论模型预测的精度更高，具有明显优势． |

| Abstract: | The accumulated generating method of gray theory can weaken the random ingredients of the load,and artificial neural networks can be adjacent to any function,a sequence which changes arbitrarily is fitted and forecasted.The experimental results show that the average relative error based on gray theory and neural network model for the optimal combination is1.307%,and this method has obvious advantages in forecast precision over BP neural network forecast and gray theory model forecast. |
| Keywords: | BP neural network gray theory load forecasting |
