The RASSA Initiative - Defining a Reference Architecture for Secure Smart Grids in Austria

The goal of the Reference Architecture for Secure Smart Grids in Austria (RASSA) initiative is to design and establish a technical reference architecture specification in coordination with all relevant stakeholders. This goal is realized across multiple projects. This paper first motivates the need for developing a coordinated smart grids reference architecture for Austria involving all relevant actors, such as infrastructure operators, manufacturers, and public agencies. After a description of most prominent international reference architecture efforts, first results on how to develop a reference architecture serving as a blueprint for further smart grids solutions is described. Necessary coordination and communication efforts to achieve a nationally accepted and internationally aligned process are described. The paper closes with an outlook on a practical application of the principles defined in order to meet stakeholder requirements through target-group-specific involvement.
