IES - Integrating the Energy System



Interoperability is essential for the success of the energy transition. The project IES Austria will design a modular process chain to achieve interoperability of standards, a specification of a normalized use of these standards in interoperability profiles and a demonstration of the processes for testing interoperability. The main issue of this project is the cross-sector knowledge exchange in the transfer of one established methodology from the healthcare domain into the electricity distribution sector.


Project targets

Interoperability is essential for the success of the energy transition and contributes to the investment protection for users as well as manufacturers and vendors. A normalized use of technical standards for interfaces and communication protocols is the central requirement for cost-effective system integration. All-over interoperability in the Smart Grid is highly important as the transition takes place gradually and new components must be integrated into an existing system.

Therefore, the focus of the IES project is to adapt and implement an existing, vendor-neutral and cooperative method to achieve interoperability within smart grids

This method – originating from ICT in healthcare - is based on a modular, well-defined process that achieves interoperability by starting with the definition of use cases, followed by cooperatively developing “interoperability profiles” which select, optimise and specify the normalised use of existing technology standards that address the well-defined use cases. These profiles assemble specific “base standards” which together provide complete technical specifications that cover all interoperability issues (e.g. data formats, transport protocols, semantics and security methods).


Technological background

As a basis, the project utilises the CEN-CENELEC-ETSI Smart Grid Coordination Group (SGCG) and SGAM from Smart Grids Mandate M/490 standards and applies the well-established Integrating the Healthcare Enterprise (IHE, ISO/TR 28380) approach for interoperability. IHE established a process for cooperatively developing “interoperability profiles” to address well defined use cases. These profiles assemble specific “base standards” which together provide complete technical specifications that cover all interoperability issues (e.g. data formats, transport protocols, vocabularies, security methods). In the EU Commission Decision 2015/1302 the IHE-profiles were released for public procurement.

In its “European Interoperability Framework (EIF) for European public services”, the European Commission recommends “formalised cooperation arrangements in interoperability agreements”, addressing legal, organisational, semantic and technical interoperability. The IHE and EIF processes (TOGAF-based architectural development provide a valid method to assess and test for interoperability of sector-independent ICT solutions.

Within the SGAM scope (Mandate M490/SGAM), interoperability was also declared a highly important issue. Thus, cross-sectoral knowledge exchange between the project partners with regard to the development of interoperability profiles and the test requirements represents this project's main innovation.


European Commission

This project conforms entirely with the targets of the European Commission and meets the content of their latest press release „Commission sets out path to digitize European industry“ (Brussels, 19th of April, 2016), which covers the strategy to create a Digital Single Market (cross sector, cross border).

In order to achieve this goal of comprehensive ICT standardisation, Europe needs the convergence of essential digital technology building blocks: 5G communication, cloud computing, IoT, (big) data technologies and cyber security to reach interoperability within the clearly named focal areas: Smart Energy, eHealth, Advanced Manufacturing and Intelligent Transport Systems (ITS).

Project results

The process ends with profile implementation and vendor neutral testing, which enables vendors to meet profile conformance and ensures that multi-vendor interoperability is realised. In the tests the methods, e.g. syntax and semantics, but also security, engineering, run time and archival purposes, will be evaluated at different interoperability levels and times (as required for multiple vendor testing).

The transparency of the method and the open platform that is used for technical specifications and profile development will be accessible by technology providers of interoperable products and services. Using this process helps foster investment protection and grow markets with increased competition for product innovation, quality and security.
