风光发电功率与用电负荷预测是保障电力系统安全稳定运行的重要工作.随着新能源渗透率与需求响应负荷的不断增加,电力系统源荷两端的不确定性均日益增强,不仅为预测工作带来了新的挑战,也对预测精度提出了更高的要求.当前关于风、光、荷预测的综述论文主要集中在单一对象,少数同时涉及上述两到三个对象,但仅在文章中对不同对象的预测方法分别进行综述.为应对源荷两端不断增加的不确定性对电力系统的冲击,一些学者同时对上述两到三个对象进行预测,然而目前尚无相关综述文章.论文提供了针对当前风光发电功率与用电负荷预测方法的全面综述.首先从相关文献发表数量、年份、国家、机构等多方面入手对现有预测文章进行概述,而后全面回顾了当前风光荷预测方法,总结分析了各方法的优缺点,并首次整理了同时包含风光荷至少两种对象的预测文章.此外,作者对直接影响短期风光发电功率预测精度的数值天气预报风速/辐照度的修正方法进行了综述.最后探讨了预测工作当前所面临的挑战和未来的研究方向.研究成果可为风光发电功率和用电负荷预测研究提供参考.“,”Wind power, solar power, and electrical load forecasting are essential works to ensure the safe and stable operation of the electric power system. With the increasing permeability of new energy and the rising demand response load, the uncertainty on the production and load sides are both increased, bringing new challenges to the forecasting work and putting forward higher requirements to the forecasting accuracy. Most review/survey papers focus on one specific forecasting object (wind, solar, or load), a few involve the above two or three objects, but the forecasting objects are surveyed separately. Some papers predict at least two kinds of objects simultaneously to cope with the increasing uncertainty at both production and load sides. However, there is no corresponding review at present. Hence, our study provides a comprehensive review of wind, solar, and electrical load forecasting methods. Furthermore, the survey of Numerical Weather Prediction wind speed/irradiance correction methods is also included in this manuscript. Challenges and future research directions are discussed at last.
