Rancang Bangun Sistem Pembangkit Listrik Tenaga Hybrid Angin dan Surya dengan Sistem Monitoring Berbasis IoT

Abstract

Electrical energy has become a major requirement in every activity. Along with the increase in population and economic activities, the demand for electrical energy has also increased. The distribution of electrical energy in Indonesia has not been comprehensive to all corners of the archipelago. The potential of solar energy can be utilized as an alternative energy source that is available throughout the year and is cheap. This research aims to determine the feasibility of a hybrid (solar-wind) generation system that can be used as a source of electrical energy for the community. In addition, this research is expected to be a solution to the lack of electrical energy supply for people who are not connected to the PLN network and offer a more economical renewable energy investment solution. A hybrid power (solar-wind) monitoring device that can view electrical output data has been designed and implemented. The tool used is a current and voltage sensor. This sensor responds to current and voltage. This tool can monitor strong current and voltage via the internet (IoT) which monitors data remotely. The test results show that this system is able to monitor current, voltage, and power with a sufficient level of accuracy. The PZEM- 004T sensor has an accuracy of ±0.5% for voltage, current, power, and energy measurements, while the ACS712 sensor has an accuracy of ±1.5% for current measurements. The average voltage generated on the solar panel is 183.983 volts while the average voltage generated by the windmill is 203.8 volts while the average power generated is 185.5 watts and the current generated is 1.02 Amperes.The IoTbased monitoring system enables real-time data visualization and helps in the analysis of hybrid power generation system performance.
