An Analysis of Hybrid Energy Design for Yogyakarta International Airport (YIA)

Abstract The potential for solar and wind energy at YIA Airport is quite large so that it can be used as a renewable alternative energy source. Based on data obtained from BMKG of YIA, the average sun intensity at YIA Airport is 6.21 kWh/m2 while the average wind speed is 3.07 m/s. This potential can be used as solar and wind hybrid energy to meet some of the electricity demand at YIA Airport using photovoltaic modules and wind turbines. Design of the wind turbine refers to research conducted by Mihai Lates and Radu Velicu (2014), which implements a basic savonius type wind turbine with an aspect ratio (α) 2, diameter (D) 3.50 m, number of blades (n) 2. Solar array design uses an off-grid system, then will be hybridized with the wind turbine. Based on the calculation result shows that the required area of the solar array is 2282.87 m2 to produce 2574 kWh/day, while the number of turbines proposed is 143 units to produce 136.90 kWh/day. With this design and based on the calculation, electrical energy will be generated for 13.55% (2710.90 kWh/day) of the total electricity demand at YIA Airport.
