Design Of Smart Automatic Transfer Switch (ATS) Electrical Energy Monitoring System As An Energy Efficiency Effort Based On The Internet Of Things (IOT)

Abstract

The design of the Smart Automatic Transfer Switch (ATS) Electric Energy Monitoring System as an Energy Efficiency Effort Based on the Internet of Things (IoT) aims to improve the efficiency of electrical energy use by utilizing IoT technology. The system is designed to automatically switch electricity sources between the main provider, such as PLN, and backup sources, such as generators or solar power plants (PLTS), when there is a disruption in the main electricity supply. The stable availability of electrical energy is essential in daily life. However, interruptions in electricity supply can cause significant negative impacts. Therefore, the development of a system that can monitor and manage energy sources efficiently is crucial. The integration of IoT technology in the ATS system enables remote monitoring and control, allowing users to access real-time information on energy status and consumption through mobile devices or the web. The process of designing this system includes several stages, namely planning, design, assembly, and testing. The technologies used include Node MCU ESP32 microcontroller, current sensor, and web-based monitoring application. The system can detect the availability of electricity supply and perform automatic switching with a fast response time, thus minimizing downtime in the event of a disruption. The test results show that the system can improve the efficiency of energy usage and can switch energy sources within 5-7 seconds, which is crucial for maintaining the continuity of power supply. The data collected during the test shows that the use of IoT technology in ATS not only improves energy efficiency but also provides convenience in the management of electrical resources. The design of this IoT-based Smart ATS shows great potential in improving electrical energy efficiency, as well as providing an effective solution to the problem of unstable electricity supply. With further implementation, this system can be a useful model for energy management in various sectors, especially in the context of using renewable energy.
