SmartNet project: TSO-DSO interaction architectures to enable DER
participation in ancillary services markets
Gianluigi Migliavacca (RSE)
This project has received funding from the European Union’s Horizon 2020
research and innovation programme under grant agreement No 691405
Agenda
 SmartNet project motivations
 Outline of SmartNet
 The simulation platform
 Five coordination schemes and their CBA
 Market architecture design
 Aggregation process
 Some (preliminary) regulatory remarks

• Five key questions:
Which implications on the on-
going market coupling process
“Some actions can have a negative cross-network effect. For instance, TSO use of distributed
resources for balancing purposes has the potential to exacerbate DSO constraints. Equally, whilst
DSO use of innovative solutions, such as active network management, can deliver benefits to
customers, if not managed properly they may in some cases counteract actions taken by the TSO”

 architectures for optimized interaction between TSOs and DSOs in managing the purchase of ancillary services from
subjects located in distribution.
 three national cases (Italy, Denmark, Spain);
 ad hoc simulation platform (physical network, market and ICT)
 CBA to assess which TSO-DSO coordination scheme is optimal for the three countries.
 Use of full replica lab to test performance of real controller devices.
 Three physical pilots are also developed to demonstrate capability to monitoring and control distribution by the TSO
and flexibility services that can be offered by distribution (thermal inertia of indoor swimming pools, distributed
storage of radio-base stations).
