The continuously increasing complexity of modern and sustainable power and energy systems leads to a wide range of solutions developed by industry and academia. To manage such complex system-of-systems, proper engineering and validation approaches, methods, concepts, and corresponding tools are necessary. The Smart Grid Architecture Model (SGAM), an approach that has been developed during the last couple of years, provides a very good and structured basis for the design, development, and validation of new solutions and technologies. This review therefore provides a comprehensive overview of the state-of-the-art and related work for the theory, distribution, and use of the aforementioned architectural concept. The article itself provides an overview of the overall method and introduces the theoretical fundamentals behind this approach. Its usage is demonstrated in several European and national research and development projects. Finally, an outlook about future trends, potential adaptations, and extensions is provided as well.

Abstract-The complexity of today's power systems is continuously increasing due to the paradigm shift towards Smart Grids. This leads to a large number of use cases that need to be covered by holistic future energy systems of which power grids are just one subsystem. However, providing information about those use cases in a structured way in order to obtain a common basis for information exchange has often not been considered in the past. Covering this gap has led to the development of use case templates in the IEC and the Smart Grid Architecture Model in the EU Mandate M/490. Furthermore, regarding the usability of these two approaches, the SGAM Toolbox and the Use Case Management Repository have been developed as appropriate tool support. In this paper, a third component for visual analysis purposes is introduced. The overall goal of the approach proposed in this paper is to integrate these three components into a comprehensive toolchain that supports the whole process from use case development to visualization in compliance to the findings of EU Mandate M/490.

Abstract-The Smart Grid Architecture Model (SGAM) is widely used for modelling, requirements engineering and gap analysis. In this paper, a formal method for engineering security requirements with SGAM is proposed. Asset security classes, risks and vulnerabilities are modelled formally and a method for deducing security requirements from these entities in the context of an SGAM model is developed. A reference implementation of this method is presented, which allows the automated extraction of security requirements from SGAM models. This set of requirements can serve as an initial starting point for a thorough security analysis. Experience from practical application demonstrates the usefulness of the proposed approach.
