This book introduces readers to the fundamentals of the IEC 62559 Use Case Methodology, explains how it is related to the Smart Grid Architecture Model (SGAM), and details how a holistic view for both architecture and requirements engineering can be achieved. It describes a standardized and holistic approach to requirements engineering for smart grid projects based on work conducted in the context of the EU M/490 standardization mandate. Over the last years, this method has been established in Europe as the basic building block of requirements engineering in the utilities sector.  The authors present a canonical, structured approach that users can apply to the Use Case Methodology and the SGAM, as well as open tools for this purpose. The application in various domains outside the smart grid is also discussed, as it can be used for critical infrastructures or system-of-systems domains like Industrie 4.0 and Ambient Assisted Living. Accordingly, the book also presents various architecture models for different fields of application, like EMAM, SCIAM, RAMI 4.0, and MAF.

Within the Smart Grid, the combination of automation equipment, communication technology and IT is crucial. Interoperability of devices and systems can be seen as the key enabler of smart grids. Therefore, international initiatives have been started in order to identify interoperability core standards for Smart Grids.  IEC 62357, the so called Seamless Integration Architecture, is one of these very core standards, which has been identified by recent Smart Grid initiatives and roadmaps to be essential for building and managing intelligent power systems. The Seamless Integration Architecture provides an overview of the interoperability and relations between further standards from IEC TC 57 like the IEC 61970/61968: Common Information Model - CIM. CIM has proven to be a mature standard for interoperability and engineering; consequently, it is a cornerstone of the IEC Smart Grid Standardization Roadmap. This book provides an overview on how the CIM developed,in which international projects and roadmaps is has already been covered and describes the basic use cases for CIM.  This book has been written for both Power Engineers trying to get to know the EMS and business IT part of Smart Grid and for Computer Scientist finding out where ICT technology is applied in EMS and DMS Systems. The book is divided into two parts dealing with the theoretical foundations and a practical part describing tools and use cases for CIM.

​Die Vision von E-Energy, einem IKT-basierten Energiesystem der Zukunft, bedarf einer sicheren, interoperablen IT-Infrastruktur als Basis. Die Architekturentwicklung von Smart Grids geht mit domänenspezifischen Herausforderungen einher und ist ein Bereich der derzeit in den Anfängen der Realisierung steckt. Dieses Buch stellt die Grundlagen für so eine Architekturentwicklung zusammen. Neben grundlegenden Techniken sowie etablierten Vorgehensmodellen des „Enterprise Architecture Management“ und des „Software Engineerings“ werden existierende Arbeiten zu Architekturen des Smart Grid diskutiert. Des Weiteren wird eine abstrakte Referenzarchitektur beschrieben, die als Grundlage für die Entwicklung konkreter Smart Grids dienen kann. Da ein Smart Grid voraussichtlich verschiedene IT-Infrastrukturen vernetzt und bereits jetzt IT-Angriffe bekannt sind, widmet sich dieses Buch insbesondere auch dem Thema der Informationssicherheit speziell für Smart Grids. Des Weiteren werden domänenspezifische Standards wie die CIM-Norm vorgestellt und Methoden zur Prüfung der Standardkonformität beschrieben. Abschließend werden einige Realisierungsbeispiele aus dem E-Energy-Projekt eTelligence für eine Smart Grid-Architektur skizziert und erste Best Practices aufgezeigt.

The first successful finished Smart Grid Prototype Projects deliver new requirements and best practices to meet them. These solutions will be the base for the upcoming norms and standards in the near future. This domain is not only part of one Standard developing Organization (SDO), but also of many different organizations like ITU, ISO, IEC and additionally for the electro mobility part the SAE. This results in many standards which are based on different aspects. Furthermore the European mirror organizations (ETSI,CEN, CENELEC) as well as the German mirror groups of these groups are involved, which are delivering further rules and adaption for the local market. Because of this diversity of organizations involved, it is difficult for the local companies (which includes energy utility, manufacturer and software producer specialized on integration) to identify the relevant trends, standardization groups and technologies necessary. With the EU Mandate M490 to CEN/CNELEC and TESI and the Commission being a driving force (e.g. ftp://ftp.cencenelec.eu/CENELEC/Smartgrid/SmartGridFinalReport.pdf and http://www.cenelec.eu/aboutcenelec/whatwedo/technologysectors/smartgrids.html) standardization becomes more and more important – but it’s complex and not easy to be understood. Here at OFFIS, we provide training but we are always asked for textbooks on our tranings. Based on our modules for the SG tranings, we would estimate the following chapters to be relevant to SG stakeholders in standardization (roughly 16-20 pages per chapter).
