Enhanced Calibration of Steady-State Wake Models for Innovative Helix Control in Wind Farms
Exploring the Influence of the Helix Approach on Model Parameters Calibration
The global demand for renewable energy is driving the rapid growth of the wind energy sector, with wind farms increasingly preferred over stand-alone turbines due to their operational and economic benefits, such as reduced deployment costs, operational efficiencies, and minimized

Closed-Loop Wake Meandering Control of Downstream Wind Turbines
Enhancing the time-varying meandering effect using phase synchronisation
The offshore wind energy sector has experienced remarkable growth in recent years, driven by increasing demand for renewable energy sources and technological advancements. As wind farms expand and turbine sizes increase, challenges associated with wake effects and turbine interac

Optimisation of the Absolute Sine for Dynamic Induction Control
Power Maximisation of a Wind Farm Through Infinite and Finite Horizon Control
The clustering of wind turbines in a wind farm results in overall efficiency losses as downstream wind turbines operate in the wake of their upstream neighbours. Wind farm flow control (WFFC) strategies have emerged to reduce these wake effects with the goal of maximising overall

An investigation into DIC using free vortex wake methods
Identifying the optimal dynamic induction control law to trigger effective wake mixing in a two turbine system
Wind farm control is an area of research that looks to maximise the performance of individual but most importantly the collective performance of wind farms. The performance of turbines located in a wind farm is heavily dependent on the effects of turbine wakes, and improving the

Identification of a dynamic center line model and its implementation in FLORIDyn
A comparison between MOESP and DMDc system identification
Wind energy plays an essential role in the transition to a sustainable future and wind turbines allow us to utilize it. Wind turbines are often installed in close proximity to make the best use of the given space and to save costs. This also has the disadvantage that the turbines
