Abstract

Abstract. Layout design and wake steering through wind plant control are important and complex components in the design and operation of modern wind power plants. They are currently optimized separately, but with more and more computational and experimental studies demonstrating the gains possible through wake steering, there is a growing need from industry and regulating bodies to combine the layout and control optimization in a co-design process. However, combining these two optimization problems is currently infeasible due to the excessive number of design variables and large solution space. In this article, we present a method that enables the coupled optimization of wind power plant layout and wake steering with no additional computational expense than a traditional layout optimization. We developed a geometric relationship between wind turbines to find an approximate optimal yaw angle, bypassing the need for either a nested or coupled wind plant control optimization. It also provides a significant and immediate improvement to wind power plant design by enabling the co-design of turbine layout and yaw control for wake steering. A small co-designed plant shown in this article produces 0.8 % more energy than its sequentially designed counterpart. This additional energy production comes with no additional infrastructure, turbine hardware, or control software; it is simply the outcome of optimizing the turbine layout and yaw control together, resulting in millions of dollars of additional revenue for the wind power plants of the future.
实现下一代风力发电厂的控制协同设计
摘要布局设计和通过风电场控制的尾流转向是现代风电场设计和运行中重要而复杂的组成部分。它们目前是单独优化的,但随着越来越多的计算和实验研究表明尾流转向可能带来的收益,工业界和监管机构越来越需要在共同设计过程中结合布局和控制优化。然而,由于设计变量数量过多和求解空间大,将这两个优化问题结合起来目前是不可行的。在本文中,我们提出了一种方法,该方法能够实现风电场布局和尾流转向的耦合优化,与传统布局优化相比,无需额外的计算费用。我们开发了风力涡轮机之间的几何关系,以找到近似的最佳偏航角,从而绕过了嵌套或耦合风力发电厂控制优化的需要。它还通过实现涡轮机布局和尾流转向偏航控制的共同设计,为风力发电厂的设计提供了显著而直接的改进。本文所示的一个联合设计的小型工厂生产0.8 % 比按顺序设计的同类产品更有能量。这种额外的能源生产没有额外的基础设施、涡轮机硬件或控制软件;这只是优化涡轮机布局和偏航控制的结果,为未来的风力发电厂带来了数百万美元的额外收入。
