Control System for Smart Home Energy Management

Abstract

The Increasing energy demand for residential load is often associated with a lot of energy waste due to lack of a good energy management system. In this work, we propose an intelligent energy management system (EMS) which is designed to control the electrical energy source from solar energy and the power plant from PLN resources both automatically and manually based on the Internet of Things. This control system can be controlled remotely during the process of connecting and disconnecting backup power sources that can be accessed through smartphone devices. Based on the test results of the control system of displacement of energy sources, the DC voltage sensor accuracy value is 99.44% and the PLN voltage measurement has an accuracy of 98.31%. In the control system transfer to a backup power source with manual control has an average duration of time of 0.74 seconds while the automatic control has an average duration of time of 0.98 seconds to 1.33 seconds and for automatic control with priority reading the battery capacity of 12.75 Volts can do transfer from the PLN power source to the backup power source and transfer to the PLN source if the voltage is less than 10.5 Volts with a 100% success rate.
