Integrated wind farm layout and control optimization [PDF]

Wind Energy Science, 2020
The objective of this paper is to investigate the joint optimization of wind farm layout and wind farm control in terms of power production. A successful fulfilment of this goal requires the following: (1) an accurate and fast flow model, (2) selection ...

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.

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

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 ...

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 ...

Economic lifetime-aware wind farm control [PDF]

Wind Energy Science
We present the economic lifetime-aware formulation of wind farm control (WFC), a novel approach characterized by two key innovations with respect to the state of the art. First, the optimization is guided by an economic model of profit.

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

Supergen Wind Hub : D3.3 Report on Wind Farm Control Algorithms to Meet Asset Management Requirements [PDF]

, 2019
In this report, the investigation of the dependence of the loads on individual turbines in an offshore wind farm is reported. Three layouts of the wind farm are considered for a wide range of wind conditions, including wind direction.
