Design of Smart Microgrid as an Integration of Electrical Systems with Android Application

The increasing demand for electrical energy, coupled with the need for sustainability, has led to the development of smart microgrids that integrate renewable energy sources and traditional grid systems. This paper presents the design and implementation of a smart microgrid system that integrates solar and wind power plants with the national grid (PLN), using an Automatic Transfer Switch (ATS) and a mobile application for real-time monitoring and control. The system optimizes energy distribution between renewable sources and PLN, ensuring a seamless transition in case of power supply interruptions. The mobile application, developed using Flutter and integrated with Firebase and Node.js, enables users to monitor energy consumption, control energy distribution, and manage financial costs. The results demonstrate the system's reliability in energy management, promoting renewable energy use while ensuring system resilience. This solution contributes to Indonesia's goal of achieving Net Zero Emissions (NZE) by 2060.
