Windfarm layout optimization with a newly-modified multi-wake model based on aerodynamic characteristics of floating wind-turbines

The aerodynamics of a floating wind turbine was analyzed, and the results were applied to a wake model by introducing a modified NOJ model. In addition, the effect of the 6-DOFs characteristics on the wind farm optimization is examined by comparing the platform type (fixed and floating) and wake mod...

Summary:The aerodynamics of a floating wind turbine was analyzed, and the results were applied to a wake model by introducing a modified NOJ model. In addition, the effect of the 6-DOFs characteristics on the wind farm optimization is examined by comparing the platform type (fixed and floating) and wake models (NOJ model and modified NOJ model). The unsteady vortex-lattice method (UVLM) is used to analyze the aerodynamic characteristics of a floating wind turbine. The relationship between the 6-DOFs motion and power performance is validated through theoretical analysis. This study proposes a modified NOJ model to consider the multiwake effect of a floating wind farm. The results demonstrate that the conventional layout optimization method has an error in the layout position and power performance due to the characteristics of a floating wind turbine. Therefore, 6-DOFs motion and its influence should be considered for accurate floating wind farm optimization.
