Abstract: In this study, the combined impact of atmospheric stability, speed-up and wake effect on the production of pairs of wind turbines in a wind farm located on complex terrain was evaluated considering the full wake effect wind direction. Prior analysis of the climate and atmospheric stability at the wind farm and the power production was carried out. It was found that the downwind turbine performs better than the upwind turbine at dawn and the atmospheric stability does not affect the ratio of power production of the wind turbine pairs. When the wind farm data were compared with the speed-up and wake effects models, it was observed that the effects are reversed, that is, when the speed-up model had small errors the wake effects model errors were large. This behavior was observed in the early hours of the morning while in the daytime the wake effects model had small errors and the speed-up model errors were large, indicating that the two phenomena are dominant at different times of the day.
