Due to widespread construction of AMI(Advanced Metering Infrastructure), various service tends to increase, which are not only remote metering service collection measuring data but also demand management and energy saving using measuring data. In order to support a stable management of such services, it is necessary for measuring data to be processed efficiently. In this paper, we analyze a performance of measured data processing efficiency using duplicated data removal according to AMI construction purpose on real environments.

AMI 기술은 스마트 미터의 검침 데이터를 수집하고 이에 대한 전력사용 정보를 수용가에게 제공하는 지능화된 전력 네트워크 시스템이다. AMI 네트워크는 공개된 통신망에서 양방향 네트워크 기술을 사용하기 때문에 데이터 전송에 대한 데이터의 신뢰성이 무엇보다 중요하다. 일반적인 AMI 통신망 구조에서는 악의적인 사용자의 공격에 노출되어 다양한 종류의 피해 사례가 발생할 수 있다. 따라서 본 논문에서는 AMI 시스템 기기에 대하여 안전한 데이터 송수신을 위한 보안적용 기술에 대하여 기술한다.

As a result of AMI rapidly expanding and distributing its products, variety of services that utilize data on the use of electricity are increasing. In order to make these services more effective, missing metric data needs to be corrected, compensating for which Euclidean similarity is used to find customers with similar usage patterns. Throughout such a process, we propose a method for correcting missing data and provide comparison with the preceding methods.

KEPCO installed AMI (Advanced Metering Infrastructure) metering system for low-voltage customers from 2008. AMI metering system of KEPCO has operated 2.55 million customers and will plan to operate 22 million customers until 2020. KEPCO developed AMI NMS (Network Management System) to operate the meter reading network efficiently. NMS monitors the network status of DCUs (Data Concentration Unit) and modems. NMS provides functionalities of data collection and analysis. It collects property data of network device, network topology information, communication performance information, fault information, and etc. It analyzes collected data and controls network devices by remote access. AMI NMS collects about 370 MIBs (Mangement Information Bases) using SNMP (Simple Network Management Protocol). This paper introduces main functionalities, designed context, and implemented service screen.

In this paper, a simulator adapted in AMI network environment with NS-2 was designed and implemented. The limited AMI operation environment such as processing times of data, network protocol and system performance can be simulated to find out the optimal AMI formations. Consequently, it is simulated under conditions that are closely analogous to the actual networks and each device. In future, the result of simulation would be applied to AMI network, mitigated the waste of resources and much contributed towards the real optimal AMI deployments in utilities.

This paper is a study on development of a new structured AMR/AMI(automatic meter reading/advance metering infrastructure) system. The developed system has a faster reading and is cheaper and easier to install compared to the existing AMR/AMI system. The system can be applied to AMR/AMI for five kinds of meters, electricity, gas, water, hot-water and calorie meter, which are used in most Korean households. Test results show that the developed system is both economical and reliable both in theoretical and practical applications. The resuts also show that the developed system is more suitable than existing system for AMR/AMI applications.

Recently the existing one-way electricity system that combines information and communications technology to develop smart grid technology is made active. The core infrastructure of the smart grid, AMI smart meters to AMR system, the amount of power measured at the top to MDMS transmits data store. Smart meters utilizing information and communication technology to transfer data and power because of the existing security threats are expected, including the additional security threats. It exposes the privacy of consumers and industrial systems, such as paralysis is likely to result in the loss. In this paper to respond to these security threats in the environment smart grid. Also, We propose data transfer methods between smartmeter and MDMS and between home device and MDMS.

취수원에서 정수장과 배수지를 거쳐 수용가에 이르기까지 공급되는 급수량을 결정하는데 있어 각 수용가별 물 사용 패턴은 수요량을 예측하여 취수량을 결정하는데 있어 매우 중요한 지표이다. 생활용수 추정은 용도별(가정용, 상업용, 공업용 등)로 분류하여 경향성이 나타날 수 있도록 과거 사용실적을 바탕으로 장래 용도별 사용량을 추정한다. 이는 경험을 바탕으로 한 것으로 일반적으로 시계열 모형을 이용하는데 수요예측의 실패 가능성이 높으며 효율적인 방법이라 할 수 없다. 이에 본 연구에서는 최근 통신기술의 발달로 양방향 통신이 가능한 AMI(Advanced Metering Infrastructure, 원격검침인프라)센서를 영종도 112블록의 528개의 수용가에 설치하였다. AMI는 스마트 미터에서 측정한 데이터를 원격 검침기를 통해 물 사용량을 자동으로 계측할 수 있다. AMI 데이터를 이용하여 영종도 112블록의 운북동과 운서동의 각 용도별, 요일별, 그리고 도심지와 농가의 실시간 물 사용 패턴을 분석하였다. 분석 결과 운북동과 운서동의 물 사용 패턴은 비슷한 경향을 보이는 것으로 보이나 도시화된 운서동에 비해 운북동의 물사용량이 상대적으로 적고 첨두사용량의 발생시간 또한 빠른 것으로 나타났다. 또한 가정용과 공공용의 경우 시간별 물 사용량이 요일에 따라 일정한 경향이 있으나 상업용과 공업용은 일정한 사용량을 보였다. 향후 112블록의 관망해석에 실시간 물사용 패턴을 적용하여 효율적으로 급수량 결정을 할 수 있을 것으로 사료된다.

In the development of MDMS(Meter Data Management System) based on CIM(Common Information Model), which is international standard in information model and data exchange on power system, the two focused issues are the effective management of data collected in a shorter time period and the way to integrate services supporting legacy system to use the AMI(AMI, Advanced Metering Infrastructure) data. In this paper, we propose MDMS implementation methods and functions in AMI environment which are differ from existing AMR system environments in that the methods support bi-directional service infrastructure. The proposed MDMS in this paper has two unique features, one is the secure of interoperability by utilizing the CIM and ESB, the other is the improvement of field application by implementing system module based on components. On an implementation of smart grid, the result of proposed methods is expected to contribute to the efficient development and operation of CIM-based power system.

In this paper, a system that integrates a home concentrate unit(HCU) in a smart electricity meter to collects water, gas, hot water, and heating usage required for AMI has been proposed. The collected data could be transmitted to the in house display(IHD) and server to provide a more economical AMI system. The developed system is less expensive in the network configuration than the existing system, which could reduce the operating cost, and be easy to install. By applying the developed system, the usage of electricity, water, gas, hot water and heating could be measured and these make it easier to apply AMI system. The main contents of the development are the smart electricity meter and embedding of HCU into the smart electricity meter, and transferring these data to IHD and server to structure the AMI system. The each developed unit has been networked to structure the AMI system to perform the actual meter reading operation and show the result.
