Study on Load Forecast of City Gas with Unstable Time Series Model
Jiao Wen-ling · Gas & Heat · 2003
Based on theory of time series analysis, this the sis introduces establishing the unstable time series model process with the properties of unstable time series for the city gas load, and puts forth the improvement method of forming model on a foundation of Box and long autoregression of white noise, and establishes unstable time series model for the city gas load with Fourier series model to describe the cyclical variation regularity and AR model to describe the stable time series.
