Distribution systems for operating the various systems should be operated organically. Distribution systems for organic operations extend the functionality of the system and system integration for the extension is doing. However, in systems integration for each unique non-standard definition of linkage and exchange systems are used. Non-standard definition of a unique linkage and exchange systems in the maintenance and expansion will result in many negative results. To solve these problems, the system and the exchange of information about the links between systems should define standards. IEC (International Electrotechnical Commission) power to solve these problems in the field of the Common Information Model (Common Information Model, CIM) standard (IEC61970, IEC61968) is defined as the transmission and distribution system integration and standardization for the exchange of information. In this paper, standardized system for building CIM-based distribution automation system should describe the process of building. In addition, the process of establishing a common information model needed (CIM) defined and associated services for a defined set of models is proposed in the standardization process.

With the advent of high technologies such as the 4th Industrial Revolution and artificial intelligence and big data, efforts are being made to solve urban problems and improve the quality of life by applying new technologies in the smart city field. In addition, as carbon neutrality has emerged as an important issue due to global warming, smart city energy platform technologies such as urban energy management, efficiency improvement, and carbon reduction are in the spotlight. In order to effectively manage urban energy, energy resource information such as electricity, water, gas, hot water, heating, etc. must be collected from the management system of various energy utilities and managed on the central platform. The centrally integrated data is delivered to external city management systems that require city energy information through an energy platform. This study developed a CIM profile for smart city energy monitoring required to provide energy data to external systems. Electric data model were designed using the CIM class of IEC 61970, and water, gas, and heat data model were designed in compliance with the UML-based design ideas of IEC 61970.

전력시스템의 배전분야 정보모델 및 데이터교환 국제표준인 CIM(Common Information Model, IEC61968) 기반 MDMS(Meter Data Management System, 미터데이터관리시스템) 개발에 있어서, 가장 중점을 두는 부분은 짧은 주기로 수집되는 데이터의 효과적인 관리와 AMI 데이터를 활용하기 위하여 상위시스템들과 어떻게 통합서비스 할 것인가에 대한 이슈이다. 본 논문에서는 기존의 AMR 환경과 다르게 양방향 서비스 인프라를 제공하는 AMI 환경에서 MDMS 구현 방안과 기능들을 제안한다. 본 논문에서 제안하는 MDMS의 특징은 국제전력표준인 CIM과 통합서비스버스(ESB)를 활용하여 상호운영성을 확보했다는 점과 컴포넌트 기반으로 시스템 모듈을 구현하여 현장 활용도 향상이 가능하다는 점이다. 본 연구의 제안된 결과는 지능형전력망 구현에 있어서 CIM 기반 전력시스템의 효율적인 개발 및 운영에 기여할 것으로 기대한다.

The main purpose of the distribution automation system (DAS) is to achieve efficient operation of primary distribution systems by monitoring and control of the feeder remote terminal unit(FRTU) deployed on the distribution feeders. DAS simulators are introduced to verify the functions of the application software installed in the central control unit(CCU) of the DAS. Because each DAS is developed on the basis of its own specific data model, the power system data cannot be easily transferred from the DAS to the simulator or vice versa. This paper presents a common information model(CIM)-based DAS simulator to achieve interoperability between the simulator and the DASs developed by different vendors. The CIM-based data model conversion between Smart DMS (SDMS) and Total DAS (TDAS) has been performed to establish feasibility of the proposed scheme.

전력거래소는 전력산업 국가전략과제 중 하나로 추진된 한국형에너지관리시스템(이후 K-EMS)의 개발(2005~2010)을 성공적으로 완수하였으며 이를 바탕으로 차기계통운영시스템(이후 차기EMS)의 설계 및 도입(2011~2014)을 위한 작업을 진행 중에 있다. 차기EMS는 EMS를 중심으로 신규 시스템과 기존 시스템이 통합, 연계되어 사용자가 필요한 데이터를 원활하게 제공할 수 있는 서비스 중심 인프라스트럭쳐를 지향하고 있으며 이를 구현하기 위한 주요 기술 중 하나로 전력계통 모델링을 위해 IEC 국제표준규격인 CIM(Common Information Model)을 적용하였다. CIM은 차기시스템의 핵심 설비인 차기EMS와 차기MOS 간 공통 플랫폼을 제공하여 시스템의 신뢰성 뿐 아니라 유지보수 비용 측면에서의 개선을 기대할 수 있다. 차기EMS는 CIM의 적용을 통해 CIM을 채택한 이 기종 시스템과의 연계를 위한 호환성 및 유연성을 가진 시스템으로 개발될 것이다.

Smart grid is called it as a system of systems. There are diverse types of systems in smart grid environment. Therefore, one of key factors to achieve smart grid successfully is interoperability among diverse systems. To secure interoperability, smart grid operating system should be developed complied with standards in terms of the data representation and communication. Common Information Model (CIM) and OLE Process for Control - Unified Architecture (OPC-UA) are the representative international standards in smart grid domain. Each standard defines data representation and communication by providing common information model and the unified architecture. In this paper, we explain a smart grid platform that we have developed to comply with CIM and OPC-UA standards for secure interoperability among numerous legacy systems.

The exchange of information with legacy systems is a main issue in the era of SMARTGRID. Because WAMAC(Wide Area Monitoring and Control) system has monitoring function, as well as control function, it is very necessary for WAMAC to exchange data and information with SCADA(Supervisory Control and Data Acquisition) / EMS(Energy Management System). IEC 61970 CIM(Common Information Model) is an abstract model that represents all the major objects in an electric utility enterprise typically involved in utility operations. In this paper, a proposal that adopting CIM to WAMAC model be submitted so that the integration of various legacy system and application for itself be able to be flexible.

The smart grid, which is an integrated type of the power system and the digital network, requires the integration of a CIM(Common Information Model) standard for information modelling at the power control centers and an IEC 61850 standard for automation at the substation level in order to efficiently exchange the information between system elements. This paper describes the method of data transfer from one standard information model to the other standard unified information model by mapping between the objects of IEC 61850 and IEC61970 CIM standards both in the static and dynamic models, and designs the method of data transfer and information exchange between the topology processing application using unified topology class packages.

An ecconomically competitive automated manufacturing system integrates the various control processes and data used in design, manufacturing, sale and service of products. CIM is a way to achieve such integration through computers and computational techniques in design, planning, and manufacturing. Developing effective CIM architectures is hampered by integration problems. The key to resolving these problems lies in a better understanding of manufacturing function and how it is related to other manufacturing functions. Integration of CIM environment requires coordinated solutions to data management problems for individual application system as well as for exchange of data between these applications. This requires a common framework for data management throughout the CIM environment. This paper discusses the design paradigm as a framework for this purpose. Designing an organizational structure to meet those goals involves 1) analyzing the functions through functional decomposition, 2) developing a data model to coordinate functions. As a result, we propose an object-oriented design methodology for manufacturing information system.

고품질, 고 신뢰도를 지향하는 미래 지능형 전력시스템에 대한 기대와 함께 전력 기기 및 설비의 디지털화에 관심이 집중되면서, 전력시장에서는 전력정보의 양방향 교환 표준을 위한 공통정보모델(CIM : Common Information Model)의 개발 및 활용이 새로운 화두로 부상하였다. CIM은 차세대 전력시스템과 미래형 부가서비스 등의 전반적인 운영측면에서 혁신을 이루는데 사용할 수 있도록 표준화된 데이터교환 모델이다. 이는 전력시스템 내 모든 다양한 객체(변전소, 송전선, 변압기, 차단기, 설비자산, 작업지시, 작업원 등)들이 어떻게 상호 연결되는지를 표현하는 방식이다. 최근 CIM/GID(GID : Generic Interface Definition)에 대한 관심이 고조되면서 CIM/GID를 어떻게 도입하고 활용할 것인가에 대한 논의가 활발하다. 그 활용 방안의 일환으로 개발된 시스템에 대한 상호 운용성 테스트를 수행함으로써 제품 또는 시스템의 표준화 준수 여부와 활용성에 대한 검증이 가능하다. CIM/GID 상호운용성 테스트는 UCA International Users Group에서 가입 회원들을 대상으로 지속적으로 진행되고 있다. 본 논문에서는 미국 클리블랜드에서 2003년 11월 18일$\sim$20일 사이에 진행되었던 5차 CIM/GID 상호운용성 테스트 결과를 토대로 CIM/GID와 CIM XML의 상호 운용성 테스트 방안을 소개하고자 한다.
