Field-scale Computational Fluid Dynamics applied to wind velocity profiles of photovoltaic plant: Case of the QEERI solar test facility, Doha, Qatar

Abstract

The scale of a photovoltaics (PVs) field exists between the regional scale and the scale of the air flow on a single PV panel. Field-scaled wind conditions are defined and used in the current study. They are designed after the case of QEERI solar test facility in Doha, Qatar, using a modeling approach based on Computational Fluid Dynamics. The modeling and simulation of such standardized ‘wind’ conditions are defined using on-field wind data collected at 2 m and 5 m. The statistics behind the experimental wind measurements are then used to calibrate the air velocity and the atmospheric boundary layer turbulence conditions for the proposed field model. The main purpose of the approach is to characterize general wind speed profiles expected in the PV arrays' vicinity, due to district buildings. Particularly, further studies can proceed with heat analyses and investigating the air flow influenced by the PV arrays and modules within the field itself. Due to the temperature effect that impacts the PV modules' performance, such approach can help predict PV plants performance under similar harsh weather conditions.
