Ancillary services from distribution networks: the view of the project SmartNet
The three-years long project SmartNet aims at comparing possible architectures for optimized interaction between TSOs and DSOs, including exchange of information for monitoring and for acquisition of ancillary services (reserve and balancing, voltage regulation, congestion management), both for local needs and for the entire power system. Different coordination schemes for the interaction between TSO and DSO are compared on the basis of three national cases (Denmark, Italy, Spain) in order to analyse the impact of DERs’ operation on the dispatching, market layout and sequencing, signals exchanged between TSO and DSO, ICT requirements and regulatory implications. The objective is to develop an ad hoc simulation platform which models all three layers, i.e. physical network, market and ICT, in order to analyse three national cases (Italy, Denmark, Spain). Subsequently this simulation platform will be scaled to a full replica lab, where the performance of real controller devices is tested.
In addition, SmartNet includes three physical pilots testing specific technological solutions:
technical feasibility of key communication processes (monitoring of generators in distribution networks while enabling them to participate to frequency and voltage regulation),
capability of flexible demand to provide ancillary services for the system (thermal inertia of indoor swimming pools, distributed storage of base stations for telecommunication).
Finally, policy provisions necessary to enable needed TSO-DSO interaction are assessed and compared with present national and European regulation.
The present session aims at collecting the main findings of the project at half way of its activities and promoting a debate on the issue of TSO-DSO interaction, that is now one of the key discussion topics at European level.
