Accompanying the advancement on the Internet of Things (IoT), the concept of remote monitoring and control using IoT devices is becoming popular. Digital smart meters hold many advantages over traditional analog meters, and smart metering is one of application of IoT technology. It supports the conventional power system in adopting modern concepts like smart grids, block-chains, automation, etc. due to their remote load monitoring and control capabilities. However, in many applications, the traditional analog meters still are preferred over digital smart meters due to the high deployment and operating costs, and the unreliability of the smart meters. The primary reasons behind these issues are a lack of a reliable and affordable communication system, which can be addressed by the deployment of a dedicated network formed with a Low Power Wide Area (LPWA) platform like wireless radio standards (i.e., LoRa devices). This paper discusses LoRa technology and its implementation to solve the problems associated with smart metering, especially considering the rural energy system. A simulation-based study has been done to analyse the LoRa technology’s applicability in different architecture for smart metering purposes and to identify a cost-effective and reliable way to implement smart metering, especially in a rural microgrid (MG).

Smart grids are alterations of the traditional power grids where the monitoring and control of the electricity system are faster and easier than before due to their automated self-healing and sensing processes. However, their primary target is two-way communication, which is only feasible if the decentralized generation of power will exist alongside the national grid. In that light, this report first gives a comprehensive description of smart grids and their history. Afterward, it examines the two major groups of challenges to the penetration of the technology; that is technical and regulatory, policy, and economic challenges. Case studies from the U.S., Canada, Korea, California, and Sweden are used to illustrate the discovered trends and challenges to renewable energy sources connected to grids and demonstrate possible solutions. The research design employed in the study is diagnostic since the problem, its history, and solutions are all reviewed in the report. The study's recommendation is policy interventions to solve both the regulatory and technical challenges to the proliferation of gridded renewables.

AbstractThis paper purposes to provide an user-friendly intelligent tool, integrating fuzzy controllers and multi-agent techniques, able to motivate and to support behavioral change of energy end-users, having as main objective to re-define the role of energy consumer in “prosumer” in the context of a reorganized decentralized energy market, now reported to intelligent grids (smart grids). Integration of interactive technologies in a decision support system for microgrids energy management optimizes: functioning from an economical point of view, active control of distributed generation, controlled consumption, loading the storage equipment. The added value of the proposed tool consists of integrating decision theory and artificial intelligence concepts in monitoring and control actions, allowing “prosumers”: to make energy usage data accessible and to demonstrate that energy savings can be achieved without compromising comfort levels.

In recent years, we have witnessed a continuous increase in the number of embedded devices with communication capabilities that are changing the way we live, work and play.  Smart grids, remote monitoring and control of all kinds of consumer devices and industrial equipment, vehicular telematics and e-health devices, are some examples of this revolution.  The communication between those devices (Machine-to-Machine communication) is leading to a complexity explosion and a strongly fragmented market. The goal of our work is to design an architecture for a generic communication system enabling many kinds of services and devices to function together in a distributed M2M ecosystem regardless of the application domain. This paper presents an initial communication architecture design for an interoperable Machine-to-Machine (M2M) system. The architecture of the system itself is divided into three main components: gateways, distributed servers and communication overlay. Gateways are designed to enable interoperability with various external systems that are, for some reason, unable to directly become parts of the M2M overlay. Servers are required to act as central points for relaying messages, providing authorization, enforcing security policies such as channel encryption and so on. Multiple intercommunicating servers, or server federation, is supported and considered an essential part of the interoperable M2M system. The overlay component refers to the logical M2M network, which is built on top of the existing ICT infrastructure.

Today’s scarcity of power generation and complex distribution through the electric power systems can not address the trend of increasing demand and consumption of electricity. The monitoring and control of the electric power systems through wired communications require expenses in material, staff, and usually fail in the effective communication for fault diagnostic and protection. In this article we discuss the possibility for the Wireless Sensors and Actuators to address this challenge and provide an optimization of the management for the electric power systems. By embedding the positive influence over the three major power systems: power generation, power delivery, and power utilization, Wireless Sensor and Actuator Networks (WSANs) emerge as an enhancing technology for the next generation of electric power systems, Smart Grids. In this paper, we present an overview of the functionalities of the WSANs in Smart Grids, their advantages over traditional networks, and their architectural characteristics in a way of supervision and control of the power system, by improving the balance between the power supply and demand, and therefore avoiding energy shortages.

Personal computers (PCs) are a powerful resource in the EM Laboratory, both as a means of automating the monitoring and control of microscopes, and as a tool for quantifying the interpretation of data. Not only is a PC more versatile than a piece of dedicated data logging equipment, but it is also substantially cheaper. In this tutorial the practical principles of using a PC for these types of activities will be discussed.The PC can form the basis of a system to measure, display, record and store the many parameters which characterize the operational conditions of the EM. In this mode it is operating as a data logger. The necessary first step is to find a suitable source from which to measure each of the items of interest. It is usually possible to do this without having to make permanent corrections or modifications to the EM.
