| Abstract: | The daily power consumption was sectionized according to its characteristics of value changing with time and temperature and corresponding dummy variables were imported.The regressive models of power consumption were established based on that method.Forecasting check took the daily power consumption of Nanjing from 2002 to 2004 as samples.Check results showed that the method was effective. |

| Keywords: | dummy variable daily power consumption forecasting temperature |
