Controlling the Operation of Wind Farm is crucial for maximizing energy production and minimizing turbine fatigue through advanced wake management strategies. Leading innovators like Siemens Gamesa, GE, Vestas, and Wobben Properties pioneer methods such as dynamic turbine repositioning, farm-level wake modeling, and pitch angle adjustments to counter wake effects and boost annual energy production (AEP). These patented approaches enable cooperative control systems that optimize power output, reduce turbulence, and lower costs, as detailed in seminal patents for floating and onshore wind farms.

Title: CONTROL SYSTEM FOR POSITIONING AT LEAST TWO FLOATING WIND TURBINES IN A WIND FARM

Inventor: ESBENSEN THOMAS [DK]; HOEGH GUSTAV [DK]; LAUGESEN KASPER [DK]

Summary of the Invention

The described control system is based on the idea to use a wake control such that floating wind turbines may be moved and/or repositioned along with a changed wake propagation direction for an improved park power output. A translation and/or a rotation of a floating wind turbine is/are used for actively repositioning of the floating wind turbine out of each other's wake. Hence, an active wake repositioning may be providable. This may result in an increase in a wind farm power production along with lower fatigue loads. Therefore, a lower level cost of energy may be possible. An increased overall power production within a wind farm along with lower fatigue loads due to a lower turbulence level may result in a reduced fatigue load such that a structural design may be optimized and therefore costs may be reduced.

Title: Wind Turbine Rotor Control

Inventor: SCHOLTE-WASSINK HARTMUT [DE]

Summary of the Invention

The embodiments described herein include a wind turbine system with a wind rotor and a control system which is configured to control the azimuthal position of the wind rotor during normal operation of the wind turbine. Accordingly, a load balance of the rotating wind rotor and/or a power uptake of the rotating wind rotor may be improved. More specifically, a time variation of an air velocity profile in the rotor plane of the rotating wind rotor is estimated by the control system and a time variation of an azimuthal position of the rotating wind rotor is adjusted to the time variation of the air velocity profile. Accordingly, a wake interaction between wind turbines of a wind farm may be reduced and thus the overall load balance and/or overall power uptake of the wind farm may be improved.

Title: CONTROL SCHEME FOR CLUSTER OF WIND TURBINES

Inventor: MIRZAEI MAHMOOD [DK]

Summary of the Invention

According to an aspect of the present invention there is provided a method for controlling a first wind turbine cluster to improve wake recovery of the wind that flows through that cluster, which may therefore improve the consistency of air flow for a downstream cluster of wind turbines. The method comprises quantifying a wake effect of the first wind turbine cluster on the operational performance of a second wind turbine cluster, identifying a triggering condition based on the quantified wake effect, and, in response, controlling one or more operational parameters of the wind turbines in the first wind turbine cluster so as to improve the wake recovery of the first wind turbine cluster. Advantageously, improving the wake recovery of the first wind turbine cluster reduces the wake effect of the first wind turbine cluster on the second wind turbine cluster.

Title: METHOD FOR OPERATING A WIND POWER INSTALLATION, CONTROLLER FOR OPERATING A WIND POWER INSTALLATION, AND WIND FARM

Inventor: BOTT STEFANIE [DE]; BRÜCK ARJUN [DE]

Summary of the Invention

According to a first aspect, provided is a method for operating a first wind power installation comprising a rotor having a rotor blade that is adjustable with a pitch angle, which generates an electrical power and in the wake of which a second wind power installation is located in at least one wake wind direction, comprising the step of: operating the first wind power installation in a substantially wake-free normal mode with a first pitch characteristic, and operating the first wind power installation in a wake-loaded wake mode with a second pitch characteristic, wherein the first pitch characteristic represents a first profile of the pitch angle and the second pitch characteristic represents a second profile of the pitch angle as a function of the electrical power, wherein the pitch angle of the second pitch characteristic is greater than the pitch angle of the first pitch characteristic for at least one range of the electrical power. It is therefore a particular finding of the present application that, in contrast to previous strategies, it is not the wind power installation in the wake that is operated differently, but rather the wind power installation causing the wake. The method therefore makes it possible to maximize the annual energy production of the second wind power installation, in particular while complying with constraints, such as compliance with maximum thrust coefficients or wake-influenced turbulence intensities.

Summary of the Invention

There exists a need for a method enabling to control a wind farm, even a large wind farm (more than 20 turbines) in a more precise way to optimize the energy produced by the wind farm. The method according to the invention may comprise one or more of the following features considered alone or in any combination that is technically possible: the state of each turbine is relative to at least one angle of rotation of the turbine among the yaw, the pitch and the tilt, the angle of rotation being preferably the yaw; for each turbine, the actions are chosen among the following actions: stand still, clockwise rotation of a certain angle relative to the current position and anticlockwise rotation of a certain angle relative to the current position; the training environment comprises a simulator enabling to calculate, for each time step, the wake effect for each turbine and the energy produced by each turbine as a function of the configuration data, of the experience data and of the actions determined for the turbines.
