基于三角函数模型的燃气短期负荷预测研究

Study on Prediction of City Gas Short-term Load Based on Trigonometric Function Model

目前国内外燃气短期负荷预测的方法很多,但没有任何一种方法能保证在任何情况下都获得满意的预测结果,因而如何提高预测精度一直是人们追求的目标。针对短期负荷的变化规律,文章应用三角函数法理论建立了预测模型。实例分析表明,该模型预测误差满足工程实际需要。

No one method can produce satisfied forecasting result at any time even though there are many methods for predicting city gas short-term load in home and foreign countries.Therefore, how to improve predictive accuracy is always a target of people seeking.Aiming at the trends of city gas short-term load,a prediction model based on theory of trigonometric function is established.Based on the example,it presents that the prediction error of this model can meet the actual needs of projects.
