Investigation of PV and Wind Hybrid System for Building Rooftop

Abstract

Solar and wind are clean energy sources with significant potential to alleviate grid dependence. This study aims to investigate the use of wind energy resources with the support of solar energy through hybrid technology for a high-rise building in Pathumthani Province, Thailand. Further, a computational fluid dynamics (CFD) simulation to determine the optimum location for wind turbine installation is conducted. The study used a hybrid model on the HOMER software to simulate the outputs of electricity, and the latter were evaluated with on-site experimental data. The CFD simulation indicates the result of some wind turbine installation points on rooftop where the surrounding small buildings and terrain can increase both the magnitude and velocity vector direction. The results of the HOMER simulation of the power production indicate that approximately 47% of the power was generated from the Photo Voltaic(PV) solar system, approximately 8% from the wind turbine system, and 45% supplied by the local grid. The renewable fraction of this system is therefore approximately 0.524. The experimental data indicate that 42.38% of the annual power production is from the PV system, and 5.87% is from the wind turbine system, indicating the potential to reduce the annual dependence on grid electricity by 51.75%.
