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 secure interoperability among different IT systems
- an open use-case based method to specify integration profiles from standards and practice
- a prototype interoperability assessment demonstration fostering agility and cooperation
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.

IES-Interoperability in Smart Energy Systems means the ability of two or more ICT systems to use and exchange both computer interpretable data and human understandable data and knowledge.
Five aspects characterise IES-Interoperability:
- Legal interoperability (e.g. laws, policies, standards & regulations conformity)
- Semantic interoperability (meaning and interpretation of content)
- Syntactical interoperability (data formats)
- Technical interoperability (e.g. machine to machine communication)
- Operational interoperability (delivering right information at right time and in right format)
IES will develop interoberability profiles including specifications for a normalised use of established standards (e.g. IEC 61850), so ...
What is an interoperability profile?
Interoperability profiles include a general section on the respective topic, called "Business Domain Overview", as well as precise technical specifications within the "Technical Framework".
--> Download the latest version of our Technical Framework for data exchanges in Virtual Power Plants.
The Technical Framework consists of two Volumes:
- Volume 1: Business Overview and Business Use Cases
- Volume 2: Integration Profiles, Description of Transactions and Actors/Subactors
What is the objective?
The objectives of the IES-project and its integration profiles are to
- provide a simple tool in order to determine if a new business use case based on real world problems can be solved using an already existing intergration profile
- create a new integration profile using a structured and predefined process, in case the new business use case cannot be solved using an already existing profile
- implement the profiled interfaces
- create reusable profiles.
Each part of the Interoperability Profile will be briefly presented below.
Business Domain Overviews
Our business domain overviews serve as information sections and as a starting point for your participation in our project. Klick on each topic to get an idea of the challenges adressed in the project and our solutions for how to solve the interoperability issue within the energy system.
Technical Framework, Example: Virtual Power Plant (VPP)
A technical framework follows a defined document structure. It desccribes new business use cases, yet DOES NOT represent a new standard. It does, however, describe the normalised used of an existing standard, such as IEC 61850 or IEC 60870-5-104.
Example: VPP-related Business Use Cases on interoperability issues
This section introduces the business use cases that have been specified for the domain "virtual power plant" using the IEC 62559 Use Case Methodology.
You can find 10 different business use cases following the entire operational pocess of a virtual power plant, from "Establish the VPP" to "Fix imbalances in the electric power system directly by the DSO".

Where are we headed?
IES' rolling process
The IES-method represents a rolling process, which restarts every year after the newest profiles were tested at Connectathon-Energy. Each summer, new profiles will be defined and developed until the IES-Plugfest in automn. They will then be further specified and will finally be tested for interoperability as well as conformity with the corresponding standard at the yearly Connectathon-Energy.
What is a Connectathon and why is it our goal to participate?
According to IHE, "a Connectathon provides a unique opportunity for vendors to test the interoperability of their products in a structured environment with peer vendors. Participants test against multiple vendors using real world scenarios following [IES] Integration Profiles specifications."
IHE-Europe published a Whitepaper on Connectathon, which explains in detail what the Connectathon is and how it is done.
We are still in the first round of the rolling process and are thus working towards our first Connectathon. In 2018, we will be part of the Integrating the Health Care Enterprise Connectathon before we will start our own Connectathon-Energy in 2019.
