Wake‐effect aware optimal online control of wind farms: An explicit solution

IET Renewable Power Generation, 2021
Wake effects impose significant aerodynamic interactions among wind turbines. To improve the wind farm operating performance, practical wind farm online control considering wake effects becomes very important.

An active power control approach for wake-induced load alleviation in a fully developed wind farm boundary layer [PDF]

Wind Energy Science, 2019
This paper studies a closed-loop wind farm control framework for active power control (APC) with a simultaneous reduction of wake-induced structural loads within a fully developed wind farm flow interacting with the atmospheric boundary layer.

Reinforcement learning for wind-farm flow control: Current state and future actions

Theoretical and Applied Mechanics Letters, 2023
Wind-farm flow control stands at the forefront of grand challenges in wind-energy science. The central issue is that current algorithms are based on simplified models and, thus, fall short of capturing the complex physics of wind farms associated with ...

Model Based Open-Loop Wind Farm Control Using Active Power for Power Increase and Load Reduction

Applied Sciences, 2017
A new wind farm control algorithm that adjusts the power output of the most upstream wind turbine in a wind farm for power increase and load reduction was developed in this study. The algorithm finds power commands to individual wind turbines to maximize

Expert Elicitation on Wind Farm Control

Journal of Physics: Conference Series, 2020
Abstract Wind farm control is an active and growing field of research in which the control actions of individual turbines in a farm are coordinated, accounting for inter-turbine aerodynamic interaction, to improve the overall performance of the wind farm and to reduce costs.

A tutorial on control-oriented modeling and control of wind farms [PDF]

2017 American Control Conference (ACC), 2017
Wind turbines are often sited together in wind farms as it is economically advantageous. However, the wake inevitably created by every turbine will lead to a time-varying interaction between the individual turbines. Common practice in industry has been to control turbines individually and ignore this interaction while optimizing the power and loads of ...

Comparison of wind farm control strategies under realistic offshore wind conditions: turbine quantities of interest [PDF]

Wind Energy Science
Wind farm flow control is a strategy to increase the efficiency and therefore lower the levelized cost of energy of a wind farm. This is done using turbine settings such as the yaw angle, blade pitch angles, or generator torque to manipulate the flow ...

A control-oriented dynamic wind farm model: WFSim [PDF]

Wind Energy Science, 2018
Wind turbines are often sited together in wind farms as it is economically advantageous. Controlling the flow within wind farms to reduce the fatigue loads, maximize energy production and provide ancillary services is a challenging control problem due

A wake detector for wind farm control

Journal of Physics: Conference Series, 2015
The paper describes an observer capable of detecting the impingement on a wind turbine rotor of the wake of an upstream machine. The observer estimates the local wind speed and turbulence intensity on the left and right parts of the rotor disk. The estimation is performed based on blade loads measured by strain gages or optical fibers, sensors which ...
