Two lidars have been applied to measure wind speeds in the wind farm. Two clusters of wind turbines in different layout patterns were chosen for the experiments. One cluster was the upstream-and-downstream pattern, which was used to investigate the upstream turbine’s wa ...

Abstract:
... A profound westward shift in atmosphere–ocean variability in the tropical Pacific is observed when 2000–2017 is compared to 1979–1999. This westward displacement is associated with changes in oceanic Kelvin wave activity along the equator, especially a remarkable reduction in the eastern Pacific (175°–145°W). This coincides with a weakening of low-level westerly winds in this region, and a westwar ...

Abstract:
... The efficiency of a vertical axis wind turbine (VAWT) can be improved by placing a shield or deflector upstream of the turbine to reduce the negative torque on the blade. However, previous studies mainly focused on fixed shields or deflectors, and the performance of the VAWT was significantly affected by the wind direction. Considering this, this paper proposed a novel passive-pitch shield (PPS) w ...

Most WF controllers proposed in the literature assume a time-invariant inflow, whereas important quantities such as the wind direction and speed continuously change over time in reality. Furthermore, properties of the inflow are often assumed known, which is a fundamentall ...
