摘要
鉴于时负荷的日周期性及周周期性，基于灰色系统理论，提出一种周期比值灰色预测模型，对未来２４小时负荷进行预测。该方法新颖独特、使用方便，可以对未来２４小时负荷进行预测，经后验差检验其精度达到一级。
In view of weekly periodicity and daily periodicity of hourly load,a periodic ratio grey model for hourly load forecasting has been set up with grey system theory.The future hourly load with in 24 hours can be forecasted with the model.With the periodicity being viewed sufficiently,satisfactory accuracy can be obtained.
