A Novel Mobile and IOT Enabled Application for Smart Energy Meter

Smart Energy Meters have significantly helped in easy reporting of energy consumption and the measurement of the same, since their introduction. They have replaced mainstream method of the house to house energy consumption data recording, but they are still reading with a lot of data inconsistencies between participating parties (energy suppliers and consumers). The purpose of this research is to develop a mobile web application with Internet of Things (IOT) and short message service (SMS) for consistent, transparent recording, monitoring of energy consumed, amount billed, infrastructure theft and meter control. Arduino, sensors and relay modules are some of the hardware components used with communication application programming interface (API) accessed through the Wi-Fi module. The communication between the hardware and the server is the response based on different commands, which includes turning on and off, setting threshold, requesting consumption and even paid for consumed power. The app will enable the consumer monitor their current energy consumption through the web and android interface and remotely turn the meter on and off. Stored data can be retrieved at any time.

Design and Development of a Power Quality Based Digital Energy Meter

In power distribution systems of many countries, service lines are directly connected to the consumer meters without any load management system. Conventional meters lack in internal power quality measurement, and utility also cannot measure the power factor and other values during the month. This study aims to design a smart kit that aids conventional single-phase energy meters and calculates the power values of all phases by measuring the voltage, current, and power factor on the load side; and the calculated power values will be sent to the cloud data base Voltage and current are measured by a current transformer (CT) and a potential transformer (PT) connected on both the incoming side and the load side in order to avoid meter bypassing. A program-based algorithm has also been developed to calculate the power factor and other power quantities. This IoT-based energy meter uploads the measured quantities to an online database, and the same are also displayed on an LCD meter. An Android™-based application is also developed for user-end control. Consumers can observe the resultant values, switch loads remotely, and pay electricity bills through the same application. When the power factor of any consumer is less than the standard value, the system will automatically notify utility company about the affecting load.

Design and Implementation of a Smart Energy Meter Using a LoRa Network in Real Time

Nowadays, the development, implementation and deployment of smart meters (SMs) is increasing in importance, and its expansion is exponential. The use of SMs in electrical engineering covers a multitude of applications ranging from real-time monitoring to the study of load profiles in homes. The use of wireless technologies has helped this development. Various problems arise in the implementation of SMs, such as coverage, locations without Internet access, etc. LoRa (long range) technology has great coverage and equipment with low power consumption that allows the installation of SMs in all types of locations, including those without Internet access. The objective of this research is to create an SM network under the LoRa specification that solves the problems presented by other wireless networks. For this purpose, a gateway for residential electricity metering networks using LoRa (GREMNL) and an electrical variable measuring device for households using LoRa (EVMDHL) have been created, which allow the development of SM networks with large coverage and low consumption.

Development of Stand-Alone DC Energy Datalogger for Off- Grid PV System Application Based on Microcontroller

This article presents a microcontroller-based direct current (DC) energy data logger developed by adapting low-cost ATmega328 by measuring the PV system DC and voltage characteristics while simultaneously recording the measured value over time to compute the energy production Watt-hour (Wh). The prototype logger has been tested on a live 1 kW standalone PV system where the voltage sensor detects PV series array output voltage ranging between 0–50 VDC by a voltage divider sensing circuit. For accurate sensing of the current output measurement from the PV array, 50A ACS756 hall effect IC was integrated as the current sensor. The data was measured and saved in text format with comma-separated values (CSV) in an SD card, read using Microsoft Excel software. The liquid crystal display (LCD) showed the actual value of the recording process’s current, voltage, power, and duration in minutes. The recorded data has been compared to the standard laboratory digital multimeter for calibration manually to justify the measurement value. The error is minimized to 0.6% average by varying the constant float value in the programming code. The advantage of developing this logger is that the development cost is much cheaper than the standard commercial PV energy meter, can be reproduced for other DC application energy measurements, and easily modify the voltage and current range to suit the application. Apart from that, this logger also provides high accuracy performance, and its independent characteristic is practical for off-grid or off-site PV system use.

A comprehensive study on energy meters and power tampering attempts

Electricity is the basic need of today’s scenario. In the 21st generation, growth and development is totally dependent on electricity. Thus, measurement of consumption of electricity becomes much more important. Energy meter used to measure consumed electricity by building or electrical equipment of various end users. This paper focuses on review of energy meters and power tampering attempts. It will highlight the development of meters from electromechanical meters to smart meters. The need of an era is to develop a more reliable and intelligent smart energy meters. This paper also discussed type of power tampering efforts in energy meters for power theft. The concept of smart meters for removing the power tampering efforts is also discussed.

GSM Based Smart Energy Meter System

This project aims to develop a smart energy meter which has many advantages like monitoring and controlling the energy meter at anywhere and at any place. Our project also called as pay first and then use it because here the user first has to pay the bill after that only they can consume the electricity. We know that each user has different kind of load demands and based on it we can recharge in number of units (KWh). The energy we are consuming and based on those pulses from the energy meter, microcontroller decrements the number of units and displays on LCD the remaining units we can use. The load gets disconnected when the units become zero and it is reconnected when the user recharges it. Our project will be very useful for the electricity board and also the user because this project gives the live update about the energy usage of the user through the message. GSM (Global system for mobile communication) will help to send and receive this information to the user. This system helps us to identify the energy losses of the electricity board to a large extent.
