Optimal closed-loop wake steering – Part 2: Diurnal cycle atmospheric boundary layer conditions [PDF]
Wind Energy Science, 2022 The magnitude of wake interactions between individual wind turbines depends on the atmospheric stability. We investigate strategies for wake loss mitigation through the use of closed-loop wake steering using large eddy simulations of the diurnal cycle ...

Wind farm power optimization through wake steering. [PDF]
Proc Natl Acad Sci U S A, 2019 Global power production increasingly relies on wind farms to supply low-carbon energy. The recent Intergovernmental Panel on Climate Change (IPCC) Special Report predicted that renewable energy production must leap from 20 % of the global ...

From wake steering to flow control [PDF]
, 2017 Abstract. In this paper, we investigate the role of flow structures generated in wind farm control through yaw misalignment. A pair of counter-rotating vortices are shown to be important in deforming the shape of the wake and in explaining the asymmetry of wake steering in oppositely signed yaw angles.

Design and analysis of a wake steering controller with wind direction variability [PDF]
Wind Energy Science, 2020 Wind farm control strategies are being developed to mitigate wake losses in wind farms, increasing energy production. Wake steering is a type of wind farm control in which a wind turbine's yaw position is misaligned from the wind direction, causing its ...

A simulation study demonstrating the importance of large-scale trailing vortices in wake steering [PDF]
Wind Energy Science, 2018 In this paper, we investigate the role of flow structures generated in wind farm control through yaw misalignment. A pair of counter-rotating vortices is shown to be important in deforming the shape of the wake and in explaining the asymmetry of wake ...

The value of wake steering wind farm flow control in US energy markets [PDF]
Wind Energy ScienceWind farm flow control represents a category of control strategies for achieving wind-plant-level objectives, such as increasing wind plant power production and/or reducing structural loads, by mitigating the impact of wake interactions between wind ...

Sensitivity analysis of wake steering optimisation for wind farm power maximisation [PDF]
Wind Energy Science, 2023 Modern large-scale wind farms consist of multiple turbines clustered together, usually in well-structured formations. Clustering has a number of drawbacks during a wind farm's operation, as some of the downstream turbines will inevitably operate in the ...

Wind Farm Wake-Steering Exploration During Grid Curtailment [PDF]
2020 American Control Conference (ACC), 2020 Wind farm wake steering is an active topic in the wind community. Yaw-induced wake steering in wind farms has shown significant increases in total wind farm power output. Unfortunately, sensor uncertainty and model uncertainty often make pure model-driven approaches less effective.
