IoT-Based Smart Energy Metering System (SEMS) Considering Energy Consumption Monitoring, Load Profiling and Controlling in the Perspective of Bangladesh

Abstract

Electricity usage is directly connected to the socio-economic growth of a society. As a developing country, the increased demand for electricity supply in Bangladesh has increased the emphasis on the need for accurate and reliable energy measurement methods. The estimation of the electricity consumption from households, institutions and industries is a must for a government to profile the country’s power capabilities and to plan for new installations if needed. From the perspective of the developing countries, mining authentic information about the ratio of the electricity consumption to its production is a matter of dilemma due to the conventional metering and billing system for the consumed electricity. In this paper, we have proposed a design which eradicates many of the drawbacks of the current system by integrating the energy measurement technology with IoT. Xtensa dual-core 32 bit microprocessor, Class 1 single phase energy measuring device, MODBUS, Wi-Fi, GSM/GPRS as communication protocols, MQTT as server, and MySQL as database system have been used in the proposed system. In this paper, real-time energy data monitoring, load control and emergency alert scheme have been demonstrated. Besides, the daily load-wise electricity consumption has been estimated throughout a week to analyze the fluctuations of three different loads considering their electricity consumption (kWh) and the balance credited (3.75BDT/kWh) on a daily basis. The output of this research has been found electrically, statically and economically very significant, which can be implemented as the next generation IoT based Smart Energy Metering System (SEMS) in the perspective of Bangladesh.
