AN IoT-BASED POWER CONTROL AND MONITORING SYSTEM FOR LOW-VOLTAGE DISTRIBUTION NETWORKS

Abstract

The Internet of Things (IoT) has become an emerging topic of social, technical, and economic significance in recent years. This paper aims to study, design, test, and implement an electric power control and monitoring system in low-voltage distribution networks based on IoT technologies. This system can be remotely controlled and monitored by using IoT devices via a personal computer (PC) or smartphone which is connected to the Internet network. In order to accomplish this goal, a complete tested system including a smart device application, a cloud-based database, an application programming interface, and a hardware setup is proposed in this paper. The electrical variables consisting of the voltage, current, real power, and energy consumption are measured, displayed, and monitored in real-time. Besides, the demand-side management (DSM) technique is also integrated into this tested system to efficiently manage a site’s energy consumption with the aim of cutting the cost incurred for power supply. Finally, this electric power control and monitoring system based on IoT technologies allows for the whole monitoring data stored in a cloud-based database that can be analyzed and reported for further purposes.
