摘要

In this communication, offshore wind energy is studied around the East of Scotland, where, among other farms, the pioneering floating wind farm Hywind-Scotland is located. SIEMENS 160/6 turbines have been implemented in this farm, and we have thus used this turbine for our study. The main purpose is to compute the Capacity Factor (CF) changes due to air density variations in the study area. The impact of seasonal air density changes has been assessed as percentage reduction, but individual extreme cases have also been considered at Hywind-Scotland farm. Temperature, pressure, and wind speed data from the reanalysis ERA5 have been used for that. As a results, in winter, the CF increment due to low temperatures and denser air reaches values around 3% and summer-winter difference can reach the 4%, that is, 0.52 GWh of energy production for one SIEMENS 160/6.
