| 摘 要： | 在讨论传统的组合预测方法的基础上,对相对误差准则下的线性组合预测进行了研究和推广。分别以"相对误差平方之和最小"、"相对误差之和最小"和"最大相对误差最小"为准则,给出了9个线性组合预测模型,其中有6个线性组合预测模型是新提出的,并且讨论了模型的解法。以美国加州电力日均价为例,给出了9种线性组合预测模型的预测结果,验证了新模型的精确性和优越性。 |

| Abstract: | On the basis of traditional combination forecast models,the linear forecast models based on relative error criteria are researched.Based on the least sum of the relative error,the least sum of square of the relative error and the least maximum of the relative error,the nine linear combination forecast models are put forward,six of which are novel,and the algorithms solving the nine models are discussed.Taking the California history daily electricity price as a study case,the prediction results are given by the nine linear forecast models.The proposed models have preferable precision and superiority to the traditional models. |
| Keywords: | combining forecasting relative error linear programming electricity price |
