Abstract

This article discusses community service activities on Gili Iyang Island, Sumenep, Madura, which focus on implementing appropriate technology in sensing the potential of renewable energy sources. Gili Iyang Island itself is an area that actively encourages the use of renewable energy. In this activity, maintenance and monitoring of data on AirFeel are carried out, including device checks and monitoring data accuracy levels through periodic calibration. Airfeel is used as a weather station to measure the potential of renewable energy, especially wind and solar energy. The potential for wind energy is considered from the speed and direction of the wind, while the potential for solar energy is considered from the level of solar irradiation. These parameters allow Airfeel to determine the optimal location for renewable energy generation based on weather conditions. Additionally, the DJI Phantom 4 Pro RTK drone was used for 3D Mapping Photogrammetry. This technology aids in creating three-dimensional maps that are considered in the planning and development of renewable energy power plants at the location. Implementing these two technologies can contribute to future planning for developing other renewable energy sources in Gili Iyang Island.

Abstract

This paper proposes a bidirectional DC-DC converter designed for photovoltaic charging systems. The converter aims to efficiently charge batteries while maintaining stable DC voltage and current output. It can convert DC power from solar panels to charge the battery and deliver DC power from the battery to the connected DC bus. The control method for the converter utilizes PI control to achieve a constant output current and voltage. The simulations were conducted using MATLAB/Simulink software, optimizing the converter’s topology, parameters, and controls according to the requirements of the PV charging system. Simulations validated the converter’s performance under various conditions, including input power fluctuations caused by changes in sunlight intensity. The results demonstrate that the bidirectional DC-DC converter effectively operates in charging and discharging modes, maintaining a stable 24V voltage in the DC bus and providing optimal charging performance for the battery.
