New Features of Automatic Meter Reading System: Based on Edge Computing

Abstract

In this paper, we focus on edge computing in smart grid and have improved the automated meter reading (AMR) system. In addition, to achieve security processing of a large number of intelligent terminals and massive data in real time and efficient responses, this paper presents an open platform which is developed on the edge of the network close to the power terminal devices or data sources, and proposes a security protection framework of smart grid based on edge computing. As a result, this new AMR system can provide real-time services, possess abilities of efficient data processing and applied intelligence, and effectively resist attacks on smart grid. Introduction With the continuous deepening of the reform of the national power system, the power sector has adopted a high-efficiency, low-cost and highly practical meter reading system, namely low-voltage automated meter reading (AMR) system [1]. In recent years, with the advancement of the national “Energy Production and Consumption Revolution Strategy 2016-2030” [2], the sales side is liberalized and the smart power service is promoted. A large number of terminal devices and multiple users on the demand side access the power grid and participate in the interaction. In this context, data flow between electrical devices and control centers, between grid companies and power users in continues to rise [3]. Moreover, with the increasing application range of electrical devices, the time and space distribution of it is more dispersed than the traditional ones, which makes the data collection and analysis face a huge test. In terms of security, the multi-power end-users supply and demand for a variety of interactive electricity, bringing convenience while serious security and confidentiality issues [4]. Therefore, power terminal security protection is unprecedentedly challenged. Related Work Edge computing refers to providing an open platform for connection, computing, storage and application near the network edge of terminal devices or data sources, and providing edge intelligent services for the data of power sensor node devices [5].Based on this, we deploy edge computing models for AMR system as showing in Figure 1, which uses the meter reading concentrator integrated edge computing module to bring some new features. It is geographically close to terminal devices and data sources, able to realize parallel processing and analysis of various acquisition terminals, intelligent devices and power user data in the smart grid at the edge of the information network. The distributed information computing service mode of edge computing with large data volume and fast response can meet the rapid response requirements of equipment and users in smart grid. According to the edge computing architecture [6], the edge security protection architecture is mainly from the aspects of device domain security, network domain security, data domain security, and application domain security.
