TL;DR: In this paper, an overview of the four parts of AMI technology (i.e., smart meter, wide area communication network; meter data management system, MDMS; and home area networks, HAN) and its benefits for smart-grid development is presented.
Abstract: Advanced Metering Infrastructure(AMI) is the totality of systems and networks for measuring, collecting, storing, analyzing, and using energy usage data.This paper provides an overview of the four parts of AMI technology(i.e.smart meter, wide area communication network;meter data management system, MDMS;and home area networks, HAN), the AMI effect, and its benefits for smart-grid development.Through system-wide communication networks AMI will link consumers and power utilities together and provide foundation for future distribution automation and other smart-grid functionalities.The system-wide measurement and visibility enabled by AMI will enhance the utilities' system operation and asset management process.It is recommended that the utilities should take advantage of AMI technology development and implementation to plan and build a common-integrated communication network and IT system in order to realize business transformation and to shape the power system towards a smart-grid.

TL;DR: The domestic and world-wide development of energy internet is reviewed, and a solution of the infrastructure for cyber-energy integration is proposed with energy routers.
Abstract: Energy is the material basis of human development. Energy Internet,which is considered as a possible solution of energy sustainability,is becoming a hot research topic and mainstream technology. Discribing the definition and features of energy internet,this paper proposes its basic architecture,and discusses the information and energy infrastructure development by introducing WAN,LAN and infrastructure. The domestic and world-wide development of energy internet is reviewed,and a solution of the infrastructure for cyber-energy integration is proposed with energy routers. The typical application scenario of the energy router is given to illustrate the cyber-energy fusion.

TL;DR: In this paper, the authors discussed the objectives, features, main technical composition of the modern power grid and its implementation sequence, and the costs and benefits of smart-grid development are depending on its execution sequence.
Abstract: The objectives, features, main technical composition of the modern power grid and its implementation sequence are briefly discussed.The four major objectives of smart-grid development are to achieve safe and stable operation of power grid, to enable distributed generation with great efficiency, to improve the utilization of the grid's assets, and to provide power for consumers with higher efficiency, reliability and quality.These objectives can technitically reach through the smart grid with close cooperation of the AMI, ADO, ATO and AAM.The costs and benefits of smart-grid development are depending on its implementation sequence, and thus the first step of smart-grid development is generally AMI while ADO is proposed to test in areas of high power quality requirement.It is suggested that even at the planning stage of a urban power grid, its long-term development should be taken into account as the flexible and reconfigurable distribution-network topology and the integrated energy and communication system architecture(IECSA) are the foundation of any smart-grid.

TL;DR: Wang et al. as mentioned in this paper proposed a nonintrusive residential load monitoring and decomposition (NILMD) method for electricity consumption details monitoring, which has advantages of simplicity, low-cost, high reliability and easiness to be rapidly popularized and used over the intrusive method.
Abstract: Nonintrusive residential load monitoring and decomposition(NILMD) technology is a novel method for electricity consumption details monitoring.Residential load details monitoring is of great significance for power utilities optimizing power grid planning,operation and management,consumers saving electricity consumption and fee,and the whole society improving the consciousness of ecological civilization,and fulfilling it into practical action.As to residential load details monitoring,the nonintrusive method has advantages of simplicity,low-cost,high reliability and easiness to be rapidly popularized and used over the intrusive method.To begin with the fundamental basis for realizing NILMD — load signature,this paper briefly discusses the basic principle,load decomposition model and solving method.NILMD technology is expected to develop into the core technology of a new generation of smart meter.Since the residential load composition is the most complicated,this technology is also available for the consumption details monitoring of industrial and commercial loads.

TL;DR: In this article, an integrated scheme for dealing with ice storm is proposed with three aspects: building up a monitoring system for important transmission lines that can activate for risk analysis of damage and thus can enhance the anti-icing capability of power grids, upgrading the design standard of transmission lines in the potential heavy ice region, and employing various measures for different areas, such as classic antiicing/deicing methods reviewed in this paper, or novel technology being developed for this purpose.
Abstract: The worldwide ice storm cases impacted seriously on power transmission systems are presented.Furthermore,with a review of literatures related to anti-icing/de-icing technology for power grids,an integrated scheme for responsing ice storm is proposed with three aspects.Firstly,to build up a monitoring system for the important transmission lines that can activate for risk analysis of damage and thus can enhance the anti-icing capability of power grids.Secondly,to upgrade the design standard of transmission lines in the potential heavy ice region,and to employ various measures for different areas,such as classic anti-icing/de-icing methods reviewed in this paper,or novel technology being developed for this purpose.Finally,to set up a decision support system to help effectually make the resource in conformity to restore the grid for quick power supply when serious ice storm befalls.
