Microscale modelling of wind turbines in the New York offshore lease area

Abstract

Abstract Simulations of the New York offshore wind energy lease area are undertaken within the PyWake program using both NOJ wake parameterization and the Fuga model. Seven different wind farm layouts are simulated to evaluate how the potential annual energy production (AEP) and capacity factor (CF) are impacted by the installed capacity (IC) density and the rotation of the wind turbines compared to the control. The control simulations use the east-west, north-south turbine layout with equidistant spacing of 1.85 km (7.7D) that will be used for the Vineyard Wind offshore wind farm south of Massachusetts. Both CF and AEP have an almost linear relationship with IC for the IC densities of 2.2 to 8.1 MWkm−2. Modelled CF are lower using Fuga (48.9% to 53.9%) than from NOJ (51.5% to 54.4%). The rotated turbine layouts have similar CF to the control because the wind direction distribution is dominated by peaks in both the southwest and northwest directions.
