Abstract:
Monthly forecast equations of daily average meteorology electric loads are obtained by using the electric loads and weather data from June to August i n 2004 and 2005. The feasibility that the daily variation of total loads is repl aced by daily variation of meteorology loads to forecast daily total loads is st udied. The weather types are divided into five kinds and the ratio of the hourly loads to the daily average loads is calculated for each kind. The hourly electr ic loads equal to the product of daily total loads multiplied by hourly ratio in the corresponding weather type. Testing forecast is made during 2006, the resu lts show that average relative errors of daily and hourly average electric load forecasts are 2.0% and 2.9%, respectively. The variation of daily electric load s with large fluctuation is well predicted.
