The Italian demonstration
Increase the Medium Voltage (MV) network's hosting capacity for Distributed Energy
Resources (DER, in particular solar), introducing Active Control and Demand Response of
MV generators, controllable loads and storage
Context
Key Figures and Highlights
Connected Power [MW]
Around 60%
connected
to the MV
network
The project involves:
• 2 HV/MV Subs
• +100 MV Subs
• +20 MV Feeders
• +5 MV Generators
• About 35.000 LV
customers impacted
Power [MW]
The main driver of the Italian demonstration is the
development
of RES (Renewable Energy Sources)
registered over the past few years in Italy.

Electric Energy Storage System
(EESS) - Functionalities
Enel has installed, closed to the MV substation “Smistamento”, a storage system
(1 MVA – 1 MWh), that can be connected to several feeders.
A variety of applications provided by electricity storage systems can be identified along the
electricity value chain, from generation support over transmission and distribution support to
end-consumer uses.
Eurelectric view of the EESS functions*
DEMO 4 is focusing on a subset
of such applications:
 Voltage Control
 Capacity Grid Support
 Losses Management
* Source Eurelectric

Network Topology
The network topology
allows the EESS to be
connected to 5 different MV
feeders (belonging to 2
Primary Substations)

First lessons learnt
 EESS is able to contribute effectively to the voltage regulation; it can
help HV-MV power flow control too (according to EESS capacity)
 The optimization horizon can cover from minutes to several days
(reliability of forecast), with a reasonable computation time
 The commissioning phase represent an important and challenging
activity:
 Software is the risky side of the project (Integration with other systems –SCADA –;
Cyber Security for maintenance accesses; Heterogeneous degree of knowledge
among actors)
 Electromechanical side of the project is less critical due to the DSO’s high level of
expertise
 Personnel Training and new tools are needed for network optimal operations
 It is necessary a TLC infrastructure capable to support information delivery

Civil Work
1 MW Storage : Lessons Learned
 The installation and commissioning of the storage asset is a new
process.
 It requires a lot of work regarding administrative, security and
training.
 One of the main lessons learned is the importance of safety
procedures.
 The work must involve every stakeholder: manufacturers, DSO
control and operation teams, fire-fighters, municipality, site owners…
 This asset has been in operation for more than one year.
