The work achieves a low cost demand side management, offers low latency control, and monitoring of user energy profile. The work introduced ACS712ELCTR-05B-T current sensor output, rectifier circuit with voltage divider output while using SIM900 GSM module as SMS IoT communication in bidirectional paths between the metering system and user. PIC16F877A controller is customized with C++ metering computations. The design provides early warning of low credit level from the metering system and recharges automatically via SMS. It allows for a periodic check of consumed energy over a period via mobile phone using SMS. The system allows user to set (program) time duration for on-demand electricity supply in the house and switches off/ON of the supply from proxy for stringent electric energy management and control. Text message is emulated as an IoT communication medium between the user mobile and meter. This paper proposes smart metering infrastructure for early warning demand side energy monitoring and control (DSEMC) using global system of mobile communication short message service.

The scalability of proposed framework is also verified by varying sensors, actuators and devices. Based on the Wilcoxon method, the significance of the increase of efficiency on power consumption is confirmed. The results show that the M2M-DC framework can control energy consumption, achieving higher energy efficiency of 26.35%, regarding the rule set. Some experiments are performed to measure the effectiveness of the system. M2M-DC is a proposed framework that connects the nodes with sensors and actuators to the backend system based on the rule set. To ensure scalability, a framework that rules number of sensors, actuator and devices are required. There are several smart metering solutions have been developed in recent years, however, they are silo solutions that pay a little attention to scalability. Internet of Things (IoT) is a trend technology implemented in many areas, of which the utilization to enhance the efficiency of power consumption is significantly important. This paper proposes machine-to-machine device connectivity (M2M-DC) framework to enhance efficiency of smart metering system by controlling electrical devices in a building. This paper only focuses on the simulation part of this project. It also highlighted the proportional relation between reactive power presence and the increased cost of electricity bills. The simulation results illustrated the proposed system's ability and responsiveness to compensate for the reactive power and correct the power factor. ![]() Furthermore, static and dynamic loads are used to test the system's capability in providing fast response and compensation. The system is simulated using Simulink using a group of blocks and equations for measuring power factor, determining the weightage by which the power factor is improved, determining the firing angle of the TCR branch, and capacitor configuration of TSC branches. In this paper, a Fuzzified Static Var Compensator consists of Thyristor Controlled Reactor (TCR) branch and Thyristor Switched Capacitors branches for reactive power compensation and power factor correction at the load side is presented. SVCs provide fast and smooth compensation and power factor correction. Static Var Compensators are hunt devices used for the generation or absorption of reactive power as desired. The necessity of balancing resistive power generation and absorption throughout a power system gave birth to many devices used for reactive power compensation. As a result, many studies are concerned with reactive power compensation. Reactive power presence in the power system increases system losses delivered power quality and distorted the voltage. DLMS/COSEM protocol is not specific to electricity metering, it is also used for gas, water and heat metering.A power system suffers from losses that can cause tragic consequences. The IEC TC13 WG14 groups the DLMS specifications under the common heading: 'Electricity metering data exchange - The DLMS/COSEM suite'. ![]()
