论文摘要
随着过去几十年中的风电场的数量越来越多,并且大型数据集的可用性,对风向流量建模的研究(优化风电场设计和运行的关键组成部分之一)正在转向数据驱动的技术。但是,鉴于大多数当前数据驱动的算法是针对规范问题开发的,那么真实风电场中流体流的巨大复杂性为数据驱动的流动建模带来了独特的挑战。其中包括高雷诺数量湍流的高维多尺度,地球物理和大气效应,唤醒流量的发展以及结合了风力涡轮的特征和风链布局等。此外,理想情况下,数据驱动的风电流流量模型应具有一定程度的普遍性。前者对于避免对最终用户的模型缺乏信任很重要,而后者最受欢迎的策略是将已知物理学纳入模型。本文回顾了有关纯粹由数据驱动和物理引导的方法涵盖的有关风网流建模的最新研究集合。我们对他们的建模方法,目标和方法进行了详尽的分析,并特别关注审查作品中使用的数据。
With the growing number of wind farms over the last decades and the availability of large datasets, research in wind-farm flow modeling - one of the key components in optimizing the design and operation of wind farms - is shifting towards data-driven techniques. However, given that most current data-driven algorithms have been developed for canonical problems, the enormous complexity of fluid flows in real wind farms poses unique challenges for data-driven flow modeling. These include the high-dimensional multiscale nature of turbulence at high Reynolds numbers, geophysical and atmospheric effects, wake-flow development, and incorporating wind-turbine characteristics and wind-farm layouts, among others. In addition, data-driven wind-farm flow models should ideally be interpretable and have some degree of generalizability. The former is important to avoid a lack of trust in the models with end-users, while the most popular strategy for the latter is to incorporate known physics into the models. This article reviews a collection of recent studies on wind-farm flow modeling covering both purely data-driven and physics-guided approaches. We provide a thorough analysis of their modeling approach, objective, and methodology, and specifically focus on the data utilized in the reviewed works.
