Analysis of Cumulative Effect of Temperature in Daily Gas Load Prediction
The relationship between the histori-cal daily gas load and temperature is analyzed,and the characteristics of cumulative effect of temperature on daily gas load are studied.A temperature correction model for predicting daily gas load is proposed based on the cumulative effect of temperature.According to the principle of correlation,a solution method for boundary temperature and maximum cumulative time of influence is proposed,and the temperature is corrected by solving the cumulative effect coefficient of tempera-ture.After temperature correction,the maximum rela-tive error between the predicted daily load and the ac-tual daily gas load decreases,and the average absolute percentage error also decreases,indicating that the method of temperature correction based on cumulative effect of temperature can effectively improve the predic-tion accuracy of daily gas load.
