IEA ISGAN Annex 6: Electricity Transmission and Distribution Systems (working period 2021-2022)

ISGAN Annex 6 deals with the possible system-related challenges in the development of future smart grids. Austria is leading Task 4 Interaction of Transmission and Distribution Networks. The main topic in the current work program relates to flexibility topologies within transmission and distribution grids. The results and analyses will be published on the one hand in a discussion paper and in condensed form in a video. Communication and dissemination activities will be targeted and conducted to different stakeholder groups.

Short Description

In Austria, the goal has been set to provide 100 % electricity from renewable resources by 2030 (on balance). This goes hand in hand with the need to integrate more renewable energy sources into the grid. A tripling of the installed wind capacity and a tenfold increase in photovoltaics is assumed. The additional capacities will be integrated into both the distribution and transmission grid.

It is expected that managing the complex interactions between volatile generation and flexible consumers across all voltage levels will become an essential part of an evolving active energy system. This results in an increased need for interaction between transmission system operators and distribution system operators, which is the focus of Task 4, which is led by Austria. For these interactions to be successful, it is necessary that both DSOs and TSOs form a cooperative alliance in which both stakeholders maximize the potential benefits of these interactions. Consequently DSOs have a greater chance of avoiding network reinforcements, reducing facility concurrency through flexibility, and obtaining more information about facilities providing system services.

In addition, TSOs receive higher market liquidity for balancing services, redispatching, etc. and a lower price for using these flexibilities. These interactions often present many challenges due to the complexity of technological, economic and regulatory barriers.

The results of the project will be a video with a high-level summary of the results and a more detailed report with more technical details.

Additionally, deliverables of other project participants will be worked on. Results from the work in the Annex will be prepared in key messages (policy messages) for the Clean Energy Ministry and RTI recommendations for Austria in the area of interaction between transmission and distribution grid operators will be given.
