ABSTRACT SOLAR PV-WIND TURBINE INTEGRATION IN HYDROGEN PRODUCTION AND ELECTRICITY GENERATION FOR HYDROGEN FUELING STATION AND ELECTRIC CHARGING STATION IN INDONESIA By: Syahril Aditya Ginanjar Student Number (NIM): 23220084 (Master Program of Electrical Engineering) This research examines the integration of solar pv & wind turbines for hydrogen production and generating electricity directly or reconverting hydrogen to electricity through fuel cells. The electricity generated from sunlight and wind is promising for hydrogen production using water electrolysis. The growth of energy system with the use of fuel cell technology requires basic understanding of fuel cell system as well as related power electronics. This research provides an overall system model including solar pv, wind turbine, electrolyzer, storage system, fuel cell systems, and grid integration model using MATLAB Simulink. Particular attention is paid to design 30 % of energy mix from renewable energy in a conventional fossil-based fuel station. The power electronics system makes the electrical output synchronized with the existing power grid. The fuel cell output to the DC link can be transferred to electric charging station with the converter and then to the grid using the three-phase ac grid-inverter. This system has the advantage of being able to generate electrical energy and as a backup energy through a fuel cell with hydrogen storage. From the modeling and simulation, solar PV is required with a total capacity of 200 kWp in an area of 3066.36 m2 and wind turbine with a total capacity of 20 kW in an area of 656 m2. The system consists of Storage Tanks with a capacity of 2 x 6 x 300 liters in an area of 71 m2, Hydrogen Production Unit (onsite) with a capacity of 10 x 5 kW and Fuel Cells Power Plant with a capacity of 10 x 5 kW in a building area of 625 m2, Public Electric Vehicle Charging Station with capacity of 1 x 60 kW, 2 x 22 kW & 1 x 3.5 kW, Hydrogen Filling Station with a capacity of 1 x 70 MPa and system integration with the existing grid with a capacity of 1 x 500 kW. The system built is able to accommodate a total of 69 units of battery-based electric cars and 43 units of fuel cellbased electric cars at ideal gas stations. Meanwhile, at standard gas stations type A (area 1800 m2), the maximum of renewable energy mix that can be achieved is 10.42%, then at standard gas stations type B (area 1500 m2) by 8.55% and at standard gas stations type C (area 1000 m2) by 5.61%. The implementation at all standard gas station is able to serve 41 units of battery-based electric cars and 22 units of fuel cell-based electric cars in a day. Keywords: hydrogen, solar PV, wind turbine, electrolyzer, fuel cell, power converter, grid.
