초록
A process for optimizing the layout of a wind farm considering the dynamic characteristics of a floating wind turbine was developed. Mathematical modeling of the rotor and wake of the floating wind turbine was performed. For the single wake analysis of a floating wind turbine, the GDW model in FAST was replaced with an unsteady vortex lattice method and a nonlinear vortex correction method. The corrected method was combined with the GCL model to perform multiple wake analysis. Ten 2MW Tjaereborg wind turbines were used for optimization. In this study, COBYLA and NSGA2 were used as the optimization algorithms that considered the annual energy production, installation cost, and grid installation cost as a cost model. The optimization was performed 2 cases by setting AEP and LCOE as objective functions. For each case, AEP increased 6% at and LCOE decreased 3%.
