Lidar measurements of yawed-wind-turbine wakes: characterization and validation of analytical models [PDF]
Wind Energy Science, 2020 Wake measurements of a scanning Doppler lidar mounted on the nacelle of a full-scale wind turbine during a wake-steering experiment were used for the characterization of the wake flow, the evaluation of the wake-steering set-up, and the validation of ...

Initial results from a field campaign of wake steering applied at a commercial wind farm – Part 1 [PDF]
Wind Energy Science, 2019 Wake steering is a form of wind farm control in which turbines use yaw offsets to affect wakes in order to yield an increase in total energy production.

Experimental results of wake steering using fixed angles [PDF]
Wind Energy Science, 2021 In this article, the authors present a test of wake steering at a commercial wind farm. A single fixed yaw offset, rather than an optimized offset schedule, is alternately applied to an upstream wind turbine, and the effect on downstream turbines is ...

A numerical study of tilt‐based wake steering using a hybrid free‐wake method
Wind Energy, 2020 This study investigates the potential of using tilt‐based wake steering to alleviate wake shielding problems experienced by downwind turbines. Numerical simulations of turbine wakes have been conducted using a hybrid free‐wake analysis combining vortex ...

Addressing deep array effects and impacts to wake steering with the cumulative-curl wake model [PDF]
Wind Energy Science, 2023 Wind farm design and analysis heavily rely on computationally efficient engineering models that are evaluated many times to find an optimal solution. A recent article compared the state-of-the-art Gauss-curl hybrid (GCH) model to historical data of three

Vertical wake deflection for floating wind turbines by differential ballast control [PDF]
Wind Energy Science, 2022 This paper presents a feasibility analysis of vertical wake steering for floating turbines by differential ballast control. This new concept is based on the idea of pitching the floater with respect to the water surface, thereby achieving a desired tilt ...

A Reinforcement Learning framework for Wake Steering of Wind Turbines [PDF]
, 2023 Ideally, optimum power for a single turbine is obtained when the wind-turbine is aligned with the wind direction. However in multi-turbine wind-farm set-up, wake effects lead to decreased power production from downstream turbine [1, 2, 3, 4, 5]. Hence, a
