中文摘要	影响电力负荷预测的因素较多,其中小水电出力的强不确定性对多小水电地区负荷预测准确率的影响尤其明显。文章首先分析了小水电发电负荷的特性及主要相关因素,根据小水电的规律性,提出了小水电负荷预测的有效方法。考虑到不同负荷成分的差异性,提出了多小水电地区负荷预测的两阶段还原法,将网供负荷分解为全社会负荷与小水电负荷,根据各自特点选择不同的适合的方法预测,再还原为网供负荷预测结果。实例验证了文中方法的正确性和有效性。文中的工作对于多小水电地区网供负荷或小水电负荷预测具有重要现实意义与实用价值。; There are many factors impacting power load forecasting, in which the impact of strong uncertainty of small hydropower output on forecasting accuracy of the region with abundant small hydropower is especially evident. In this paper, firstly the characteristics of small hydropower generation load and main correlation factors are analyzed; then according to the regularity of small hydropower, an effective method for small hydropower load forecasting is proposed. Considering the diversity of different load components, a two-phase reduction method for region with abundant small hydropower is put forward, which divides the loads supplied by power network into whole social load and small hydropower load, which are forecasted by different appropriate methods according to their respective features, and then the forecasting results of different load components will be incorporated into the forecasting results of loads supplied by power network. A case is given to demonstrate the correctness and effectiveness of the proposed method. Results of this research are available for reference to forecasting of small hydropower load and forecasting of network-supplied load in region with abundant small hydropower.; 高等学校博士学科点专项科研基金资助项目(200800030039)~~
