PERFORMANCE ANALYSIS OF FLAT WINGLET DEFLECTOR ON HYBRID SOLAR PV-WIND TURBINE SYSTEM: CASE STUDY ON TWISTED SAVONIUS TURBINE
Abstract
The harnessing of clean energy from solar and wind constitutes the foremost renewable energy source in Indonesia. The amalgamation of these energy modalities holds the promise of heightened energy efficiency coupled with reduced maintenance expenditures. This investigation endeavors to synergize wind turbines with photovoltaic (PV) solar panels in a hybrid configuration, capitalizing on the turbulent effluent from the wind turbine system as a cooling medium for the solar PV panels. Further studies are needed regarding the Solar PV-Wind Turbine hybrid cooling system, as a system needs to be designed to optimize the direction of airflow from the turbine as a cooling medium for the solar PV panels without compromising the turbine's performance. Experimental-scale modeling is implemented in this study, introducing a flat winglet deflector configuration to refine and optimize the airflow dynamics traversing the turbine, directed towards enhancing the performance of the integrated solar PV-Wind Turbine hybrid system. The results showed that the installation of solar PV panels and the addition of a flat winglet deflector configuration could improve the performance of the turbine. The highest Cp and Ct values obtained were 0.18476 and 0.66404 with an increased value of 21.74% and 20.56% respectively. Using the Taguchi method, the most optimal configuration for Cp is obtained for installing a PV solar panel with a height of 10cm with AoA for installing a flat winglet deflector of 5°. In the ANOVA analysis conducted, it is known that AoA has an effect of up to 71.57%, while the panel height has an effect of 24.69% with an error percentage of 3.73%.
