Aerodynamic interactions among wind turbines diminish power generation in offshore wind farms. Adjusting a turbine’s yaw angle, deliberately misaligned from the wind direction, mitigates energy losses from wake effects, thereby enhancing overall power generation.
Up to 25.6% power gain achieved through yaw control in a two-turbine array. Turbulence intensity and turbine spacing are key factors in power gain optimization. Spanwise to streamwise distance ratio is critical in determining optimal yaw angles. Aerodynamic interactions among wind turbines diminish power generation in offshore wind farms.
The wind direction characteristics of different wind turbines (WTs) in different wind farms are diverse and some may have obvious differences. The WTs are prone to ‘over-yaw’ and ‘under-yaw’ conditions adopting constant yaw threshold and the same control strategy, which reduces the utilisation efficiency of wind energy.
To incorporate a change in wind direction, the downstream turbine coordinates (x and y) should be modified using a rotation matrix that accounts for the angle difference between the new wind direction and east, and then provided to the model.
Our home solar PV systems and energy storage products are engineered for reliability, safety, and efficient deployment in Polish conditions. All systems include comprehensive monitoring and control with remote management capabilities.
