摘要
由于风电具有很强的随机性和波动性,因此大规模风电并网会对电力系统的运行和稳定性造成很大的影响。如何准确预测区域风电场的功率已经成为当今电力系统亟待解决的研究课题。现有的风电功率预测方法未考虑空间相关因素,预测体系有待进一步完善。基于空间相关性的风电功率预测是一种考虑了本地信息和空间相关信息的综合预测方法。文中给出了基于空间相关性的风电功率预测的定义、概念和基本特点,分别从统计模型、物理模型、空间降尺度过程和空间升尺度过程4个方面详细阐述了基于空间相关性的风电功率预测的实现方法,并对空间相关性在风电功率预测方面应用的最新国内外研究进展作了系统的分析评述。最后,针对该领域尚存在的问题与不足,总结了今后的发展方向和需要进一步探索的研究内容。
