| 摘 要： | 由于电力系统负荷具有很多不确定因素 ,用单一预测模型进行预测时 ,其预测精度不高。为提高预测精度 ,完善预测方法 ,提出组合预测模型 ,对电力系统负荷预测的多种预测模型进行组合优化 ,用最小二乘法确定其权重 ,得到权重的解析表达式 ,使组合预测理论进一步得到完善。

| Abstract: | Because of too many undefined factors in the electric power systems,the forecasting results using the single signal forecasting model are unsatisfactory.To get a better accuracy and improve the forecasting method,the combined forecasting model is proposed.By using the LMS method,the weight number expression is gained. |

| Keywords: | electric power load combined forecast model weight number least square method |
