Procurement and activation of resources from distribution network for ancillary services will require new grid organisation for ensuring and improving interaction between TSOs and DSOs. EU H2020 project SmartNet proposes five different architectures or coordination schemes (CSs) that each present a different way of organizing this interaction with a specific set of roles taken by the system operators and detailed market design. The study made a comparative evaluation of these CSs based on realistic scenarios for 2030 and implemented in simulations. The following study made a comprehensive screening of more than 40 documents based on a selection of key topics, which are essential for SmartNet and evaluated how the CSs are aligned with the present national and European policy goals and positions of the key industrial stakeholders. The screening was structured according to a set of so-called topics of interest, which the project considers to be essential for definition of well functioning TSO-DSO interaction.
