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.

Join the IES team for the first Connectathon Energy in The Hague/The Netherlands, 17 - 19 April 2018!

IES designs procedures and test tools based on existing IHE modules and functionalities applicable for smart energy systems. Interoperability and conformity tests will be demonstrated for the energy sector for the first time at Connectathon Energy during the IHE Connectathon. Please find the preliminary additional conference programme ‘Energy’ in the invitation flyer.


The one-week IHE European Connectathon 2018 will take place along with Weekonnect, a three-days conference (April, 17th to 19th 2018) on secure and reliable data exchange in healthcare and other sectors. At IHE Connectathon, over 300 developers from software vendors will be testing the interoperability of their health information systems face-to-face.
If you are interested in joining our delegation or want to tell us about your interoperability pain, please contact the team of the Technology Platform via e-mail or telephone. We will keep interested parties up to date regarding the conference programme & registration details.

Defining IES-Interoperability

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.

Part I: Energy

Part II: Interoperability

Part III: Health Care (as reference)


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.

So be bold and ...
