| 摘 要： | 扩展短期负荷预测方法利用最新的历史负荷数据，预测当日当前时刻以后若干小时的未知负荷，其预测精度明显高于常规的短期负荷预测。为满足电力市场实时交易对负荷预测的新要求，将这种方法应用于修改历史负荷坏数据和补足当日未知负荷数据，以协助提高短期负荷预测的准确度。文中详细介绍了这两种应用的背景和实现原理，并以实际电力系统的应用结果数据证实了这两种应用方案是有效的和实用的。

| Abstract: | Using the latest historical load data, the extended short-term load forecasting method can forecast the unknown load during several hours after the current hour in that very day. The forecasting accuracy is much higher than those from conventional short-term load forecasting methods. In order to render improvement of the accuracy of short-term load forecasting, this method is applied to revise the bad data in historical load data record and to complement the unknown load data of that very day. The backgrounds and implementation principles for these two applications are presented in detail and the results of practical examples show that the above mentioned application is effective and practicable. |
