摘要
风力发电是可再生能源发电技术中发展最快的一种,是一种理想的、无污染的洁净能源。但是风力发电具有波动性、间歇性和随机性的特点,大容量的风力发电接入电网,势必会对电力系统的安全、稳定运行带来严峻挑战。对风电场的出力进行短期预报,是解决这一问题的有效途径。在参考阅读大量国内外文献以及作者工作的基础上,首先对风电场出力预报的划分方法进行了探讨;结合我国风力发电发展的实际情况,分析了进行风电场出力短期预报的意义和必要性;然后对风电场出力短期预报的原理、方法以及国内外研究现状进行了总结;最后指出风电场出力短期预报研究中存在的问题和今后的研究方向。
Wind power is the strongest growing form of re- newable energy and an ideal pollution-free electric power. But wind power is fluctuant, intermittent and stochastic. The large capacity wind power connected with the power grid will bring austere challenge to the safety and stabiliza- tion of power system operation Short-term wind power pre- diction is an efficient approach. This paper discussed the partition of wind power prediction. Based on lots of litera- ture and the author＇s work, combined with China＇s situa- tion, the sense and necessity of short-term wind power pre- diction are analyzed. The principle, method and status quo of short-term wind power prediction are summarized. The existent problem and research direction are discussed.
