Needs, challenges and opportunities of TSO-DSO coordination

There is a trend across the world, towards utilizing more distributed energy resources (DERs) and an increased involvement of "active consumers" in energy supply.

The transition from a system comprised primarily of dispatch-able generators to a system increasingly reliant on intermittent power sources increases the variability, uncertainty and thus also the need for flexibility.  DERs and “active customers” can provide more flexibility and thus more services to both Distribution System Operators (DSOs) and Transmission System Operators (TSOs).   This shift toward distributed and renewable electricity supply poses challenges to both the TSO and DSO; however, it also encourages exploitation of less utilized coordination synergies to achieve mutual benefits.

The coordination between TSOs and DSOs is of utmost importance for the grid to obtain the full value from services potentially provided by DERs such as, congestion relief, reactive power, voltage control and frequency reserves.

The public workshop will explore the needs, challenges and opportunities of TSO-DSO coordination from a broader perspective accounting for technical, market and regulatory aspects and different views from national/international TSOs, DSOs, and smart grids projects.


The participation is open to the public and free of charge, but a registration is necessary.  Please, register until Friday, 20 September 2019, at …
