| Abstract | The abstract provides a clear and brief statement of the content of the resource. | This report summarises an investigation into the impact of offshore wind farm design parameters (power density and inter-array spacing) on energy yield for generic projects, using the TurbOPark wake model. |
| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The influences of build-out density, buffer distance between projects, and seabed utilisation were examined by assessing the 21 individual configurations summarised in Table 1. In each study, a 1 GW wind farm comprised of a 7 x 7 array of 20.4 MW turbines is used as a basis. The wind farm layouts considered for each sensitivity are discussed further in Sections 2.1.1 â?? 2.1.3. Increases in wake loss with decreasing turbine spacing are well understood using conventional wake models. In this study, to revisit this question considering more recent developments in these methods, a single 1 GW wind farm is modelled in isolation for typical build-out densities in the range of 3 to 8 MW/km2. As shown in Figure 1 and Figure 2, this was achieved by varying the turbine spacing uniformly in both Northing and Easting directions between 10.9 and 6.7 rotor diameters, respectively. Density values throughout this report are based on the area enclosed by the square perimeter of the wind turbine locations. To examine the sensitivity of farm-to-farm wake loss to separation distance between wind farms, two 1 GW wind farms of 6 MW/km2 build-out density were modelled with a separation between 2 and 20km as shown in Figure 3 and Figure 4, respectively. Turbine spacing is measured between the nearest turbine rows of the respective wind farmsand the farms are spaced along the North â?? South axis. The case with 2km turbine spacing (run ID 7) is equivalent to a single contiguous 2GW wind farm (for a build-out density of 6 MW/km2). It is expected that the absolute production of this configuration of wind farms would depend, to an extent, on the alignment of the wind farms with respect to the prevailing wind direction. However, different layout orientations are not considered in this study as the separation distance rather than direction is expected to be dominant. For more information, see the report. |
