摘要
通过对原始数据的定性分析,提出了利用缓冲算子对历史负荷序列进行作用,有效地控制灰色模型的发展系数,较好地解决了负荷预测偏差较大的问题。实例表明了运用序列算子作用后生成的缓冲序列建模,预测的精度和适应性都大大提高了,该方法在负荷预测中有较强的实用性和推广性。
Through the qualitative analysis of original data, the developing modulus is effectively controlled because of the buffer operator acting on the historical load list, and the precision of load forecast is improved, the application area of grey model is enlarged. It shows that this algorithm is of fairly highly practical value and can be popularized.
