Italian Divertor Tokamak Test Facility [Special Technical Session]
This special technical session is connected with Track 4.5
Dr. Pietro Zito, ENEA, Italy
DTT facility is part of the general European programme in fusion research. Its specific role is to cover gap on the power exhaust for DEMO. Main tasks are: to test alternative divertor solutions; to improve heat exhaust. This tokamak will be built and installed in Italy at Frascati ENEA laboratories, with superconducting Toroidal Field and Poloidal Field magnets system capable of confining high temperature plasmas (plasma current up to 5.5 MA and magnetic field 6 T) for 100 s flat top plasma current, with heating and current drive power up to 45 MW coupled to plasma.
The toroidal field magnetic system is composed by 18 toroidal superconducting magnets that confines the plasma into the vacuum vessel. They are connected in series and fed by a Toroidal Field Power Supply (rated current 50kA and rated voltage 100V), including a crowbar protection system and three Fast Discharge Units (FDU) for quench protection. Furthermore, 12 high current poloidal power supplies (rated current 30kA and rated voltage 1kV) feed 6 central solenoid and 6 poloidal field superconducting magnets, including FDUs and Switching Network Units (SNU) connected in series for the breakdown of plasma. Finally, the heating and current drive systems are composed in particular by the Electron Cyclotron Resonance Heating (ECRH), the Ion Cyclotron Resonance Heating (ICRH) and the Neutral Beam Injection (NBI) and they are all crucial systems for DTT to be DEMO relevant.
In this framework, we encourage the submission of papers dealing with (but not limited to) the following topics:
- Large / medium size tokamak and its main systems
- Superconducting magnets;
- High current power supplies;
- High voltage power supplies;
- High Voltage AC power cable connection;
- HV/MV Sub-Station to power both pulsed and stationary electric power systems;
- Power supply for vertical stabilization of plasma;
- Quench protection systems;
- Static Var Compensation (SVC) and Filtering systems;
- Additional heating and current drive systems.

Distributed Ledger Technology as Key Enabler for Distributed Energy Generation Community (DEGC) [Special Technical Session]
This special technical session is connected with Track 4.6
Dr. Giuseppe De Marco, Evolvere SpA
Nowadays, the problem of optimization of smart grids, composed of myriads of micro-virtual power plants, is of great concern, from the point of view of the grid authority which must tackle both the variability of injected energy and the management of energy transactions. In this regard, the performance figure of any solution must account for costs versus benefits.
Part of the costs are due to the information infrastructure needed for communities of such virtual power plants (VPP), usually made of many so-called prosumers, i.e. users equipped with Renewable Energy Sources (RESs) as Photovoltaic (PV) systems with or without electric storage hardware (batteries). In this context, it has been proven that the DLT can be a viable key enabler for simplifying the management of energy transactions among members of such communities. However, many aspects have to be carefully analysed, such as:
- energy efficient consensus protocols for safe insertion of transactions record;
- easy of management from the central management of communities, known as Aggregator;
- analysis of security risks or attack models in such contexts.
This Special Technical Session is aimed at attracting researchers from academia and industry to present best practices and original solutions grown in the context of the management of distributed energy generation.
The topics may include, but are not limited to the following:
- DLT technology: Protocols, Energy Analysis, Best Practices, User Cases, Attack Models;
- Environment impact and energy net-balance analysis of DLT and related technology;
- DLT and Software: Current state-of-the-art of software engineering crafted for the on-field implementation of DEGC;
- DLT and IoT/IoE: how the DLT can be integrated within the technology around Internet of Things and Everything;
- Smart Contracts for Energy Systems;
- Transactive Energy Systems and DLT;
- Legal Aspects in Blockchain Applications in Energy Systems;
- EnergyCoins: Crypto currency in the context of energy transactions among members of DEGC;
- Automation of Energy transaction in Machine-to-Machine contexts;
- Beyond DLT: alternatives to blockchain.
