Empowering energy conservation: A prototype of household energy consumption monitoring based on Internet of Things

Abstract One of the obstacles to control household energy consumption is unavailability electricity instruments/tools to monitor electricity energy consumed by appliances causing a lack of awareness of household energy saving. Energy meter installed on buildings only show electricity consumption in total. This study aims to design and create a prototype system that can monitor and control the electrical appliances usage utilizing the Internet of Things (IoT)-based electronic devices where electricity usage data is stored in Firebase real-time database. The methods carried out are arranged in several stages, starting from data collection, design, configuration, and implementation. The tools used in this research will utilize the ESP8266 as the microcontroller, the PZEM-004T as current sensor and the Blynk as the web server. The tool will send current voltage (Volt (V)) and capacity (Watt (W)) data and then converted to energy and also the costs incurred from electricity usage based on the basic electricity tariff of National Electricity Company (PLN) and the results can be seen directly through IoT (i.e. smartphone, PC, laptop). The accuracy of power measurement by the system is 97.4% compared to measurement used by watt-checker. The results of this study show that an electrical power monitoring system makes people easier to monitor electrical power consumption by appliances used. The pilot measurement shows that a unit system can monitor electricity usage for four units of electronic equipment i.e. water pump, Television, fridge, electrical iron, rice cooker, etc. precisely and succeeded to control and increase energy saving awareness to reduce electricity consumption at the end.

An Electrical Power Inventory and Monitoring System

The Inventory Management and Monitoring System is a software that is helpful for the various business sectors that operate in stores, products, and services where storeowners, products and services proprietors keep the records of sales and purchases, supply and demand, and risk and opportunities. A mismanaged inventory means disappointed customers, too much cash tied up in warehouses, slower sales, and sometimes detrimental to the work relation environment, investments and businesses, and most probably financial losses. Inventory control problems often result in record and physical count discrepancies which may ultimately lead to higher than preferred inventory levels. Conversely, accurate inventory records result in lower inventory investment and are the foundation for forecasting, ordering, tracking, vendor evaluation, dead stock, and administration plans and decisions. The researcher observed that most of the application of the inventory system was sales and products. Through this study, the researcher applied inventory in terms of electrical maintenance relations which includes electrical supplies, devices and equipment, services, and electrical power consumption. An Agile software development methodology was used in developing the system. The inventory archive maintenance system was developed using Java, HTML, CSS, PHP, PhpMyAdmin, and MySQL. The Inventory System includes Messaging, Supplies Inventory, Job Orders, Repair Records, and Wattage Consumption. Integration of disciplines made the study finished and the user’s manual was produced for guides and references for the use of the system.

Design and Implementation of Electric Power Patrol Monitoring System Based on Beidou and Mobile Network

Most existing communication technologies used for power inspection systems cannot seamlessly cover the inspection line range. Therefore, the real-time transmission of inspection information and the safety of personnel are difficult to guarantee. Based on current research on electric power inspection and the industry’s urgent need for real-time and accurate location information of inspectors, this paper designed and developed an electric power patrol and monitoring system using the Beidou satellite system in conjunction with mobile networks. The problem of patrolling information in blind areas where ground communications cannot be reached in real time is effectively solved through a seamless switching design between Beidou short messages and mobile networks. The short message broadcast and high-precision position information return of inspection personnel were also realized by applying the Beidou multi-mode data transmission module as independently developed. The system took advantage of the user and function-oriented conceptual design and the Browser/Server (B/S)-based architecture design, as well as the combination with the SpringMVC + Spring + MyBatis (SSM) to improve the quality of the development process. Some key functions, such as real-time position display, track playback, user information management, and other functions, are interactive with the implemented visual user interfaces, which fundamentally helps the power monitoring department provide remote visual supervision services. The test results of the core module showed that the system could be used as a supplement to the power inspection and supervision industry, especially for deep mountain valleys, dense forests, and other areas without stable communication signals.

A dominance based rough set classification system for fault diagnosis in electrical smart grid environments

Nowadays, power grid monitoring systems are shifting towards more disseminating and distributive operations. The diagnosis of faults using knowledge discovery techniques has become an essential component of the process, accounting to the challenges faced by the electrical power monitoring systems. The system's operators employ various energy management techniques which play important roles in the overall management, reliability and operational sustainability of smart grid utilities. Sometimes, these systems are disrupted by events like a short circuit in the system or any external incursion that could pose a threat to the public safety as well as to the critical infrastructure of the grid. This paper aims at providing a robust system for fault diagnosis using the status of an intelligent electronic device and circuit breakers which can be tripped by any kind of fault. To protect the system from vulnerabilities and different kinds of faults, a multilayered fault estimation classifier, based on the Dominance based rough set is proposed. This technique provides an effective solution to the system's operator for the proper diagnosis of the faults and intrusions by classifying the state of the system. In addition to this, the operator can take preventative measures to protect the system from further damage.

가정용 전력 모니터링을 위한 전력신호 분석 알고리즘 개발

This paper presents an algorithm identifying devices that generate observed mixed signals that are collected at main power-supply line. The proposed algorithm, which is necessary for low cost electric power monitoring system at appliance-level, that is non-intrusive load monitoring system, divides incoming mixed signal into multiple time intervals, calculating difference-signals between consecutive time interval, and identifies which device is operating at the time interval by analysing the difference-signals. Since the features of one device can remain when the time interval is short enough and the features are independent and additive, well-known classification algorithms can be used to classify the difference-signals with features of N individual devices, otherwise features might be necessary. The proposed algorithm was verified using data mixed in a laboratory with individual devices`s data collected from field. When maximum 4 devices operate or stop sequentially and when features satisfy the requirements of proposed algorithm, the proposed algorithm resulted nearly 100% success rate under the constrained test condition. In order to apply the proposed algorithm in real world, the number devices shall increase, the time interval shall be smaller and the pattern of mixture shall be more diverse. However we can expect, if features used follow guidelines of proposed algorithm, future system could have certain level of performance without the guideline.
