Presentation of the Traffic Light System Design for Local Flexibility Markets at the SAEE Conference

On the 22nd of November, the School of Economics and Business in Ljubljana hosted the SAEE conference on energy economics. As part of the session Analysis and Development of Energy Markets and Systems, Janez Gregor Golja from UL presented the paper “Design of a Traffic Light System for the Effective Operation of a Local Flexibility Market within the STREAM Project.”
The presentation detailed the design concept of the Traffic Light System (TLS) developed within the STREAM project. Janez explained the four TLS stages and how they enable the effective operation of local flexibility markets while ensuring grid stability. The presentation highlighted the TLS’s integration within the STREAM ecosystem, focusing on its interaction with key tools, sMART and sGRID.
To provide the necessary context for understanding the TLS stages, two key concepts were introduced: the distinction between planning and operational limits in distribution grids and the use of connection agreement solutions in the orange stage. These concepts clarify the logic behind the TLS stages and their application in managing grid flexibility and congestion.
The presentation concluded with a practical example of TLS operation, demonstrating its functionality in real-world scenarios. This example helped illustrate how the TLS can proactively address grid congestion and support the development of local flexibility markets.
