本研究探討以氣溫輪廓的概念融入以類神經網路為核心的負載預測程式,配合近幾年的每小時歷史負載資料、每小時歷史氣溫資料、每日最高、最低溫及假日等資料,來預測台電短期負載,並分析此負載預測結果的準確性及特性。分析結果發現,採用氣溫輪廓後的負載預測結果,準確度明顯較沒有使用氣溫輪廓的負載預測結果高很多。除使得在氣象局雖未提供未來一周24小時氣溫預測資料時,能採用歷史24小時氣溫值協助負載預測外,更提高負載預測的準確度。期能應用本負載預測方法於電力公司相關運轉工作。
This thesis is used to investigate the short term load forecasting of Taipower system using temperature profiles and neural networks. The historical hourly load data, historical hourly temperature values, highest and lowest temperatures of each day, and holiday indices are used. It wants to obtain one-week short-term load forecasting values and the results are compared with the actual values. From the research results, the forecasting values using temperature profiles are more accurate than that without temperature profiles. The historical 24-hour temperature values also could be used even if the forecast temperature values are not given. The load forecasting results are better than ever. It is hoped that the results in this thesis could be helpful to Taipower.
