Conference:Experimental research and DER integration
in the EU Energy System
Milano, October 10th 2013c/o RSE
The FP7 Grid4EU Demonstration Project within the EEGI roadmap:
a focus on the Italian Demo experience
Lilia Consiglio, Enel Distribuzione SpA
Enel: a world dimensionFocus on major areas of presence
• Lead by 6 DSOs (covering more than 50% of the metered electricity customers in Europe)
• 27 partners (Utilities, Energy Suppliers, Manufacturers, Research Institutes)
• Duration: 4 years (November 2011 - Jan 2016)
• Total Cost: 53M€ ca (Max EC grant 25.5 M€ ca)
• Project Coordination: ERDF• Technical Director: ENEL Distribuzione• Chairman of General Assembly: IBERDROLA
Grid4EUA European smart grids project
• Increasing network hosting capacity of Renewable Energy Sources
• Implementing active, more efficient participation of customers to
electricity markets (Active Demand)
• Implementing active control of Distributed Energy Resources (DER)
• Secure energy supply - Network reliability
• MV / LV network Supervision & Automation
• Improving peak load management through increased interactions
between network operation and electricity customers
• Electric Vehicles, Storage
• Micro Grids & islanding

The development of RES in ItalyConnections to Enel Distribuzione’s network
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
The Italian DemonstrationObjective description
Milano, RSE 10 Oct 2013
Conference: “Experimental research and DER integration in the EU Energy System"
Project is located in Forlì – Cesena(Emilia Romagna, Italy)
2 HV/MV substations, 20 MV lines,110+ MV substations andabout 35,000 LV customers impacted
High penetration of RES, mostly photovoltaic(about 105 MW)
Low consumption area
Back-feeding phenomenon from MV to HV

Conference: “Experimental research and DER integration in the EU Energy System"
HV/MV Substation "Cesena Ovest"
HV/MV Substation “Quarto"
MV/LV Substation “Smistamento"
Site description (2/2)
The realization of an advanced control system communicating with the renewable generators, HV/MV & MV/LV substations and storage facility.
The realization of an “always on”, IP standard-based communication solution connecting all the relevant nodes in the network (wireless, wired and PLC)
The installation of a storage facility (1 MVA / 1 MWhapprox.) connected to a MV power line

Anti-islanding DemandResponse
Use Cases
• VR identifies optimal network working conditions (V and I inside allowed ranges)
• VR relies on different controllable resources: – HV/MV substations On Load Tap Changer (OLTC) and capacitor banks– Reactive power injection/absorption by Distributed Generation– Energy Storage System (ESS): active and reactive power injection/absorption
• Energy Storage System State of Charge (SoC) is managed according to load and generation forecasts
• Objective function: to minimize the overall cost of control actions
The advanced voltage regulator (VR)Developed by RSE
Test Network (MV bus-bar, 2 feeder)• 139 MV and MV/LV nodes (15 e 20 kV) • Total load P = 15.51 MW e Q = 7.58 Mvar• 19 generators, total generation capacity P = 9.48 MW Q = 4.165 Mvar
(PV; Mini-Hydro, Biomass, etc).
More than 32 test cases defined• Load profiles (summer/winter, working days/not working days)• Storage connection• Controllable generators (only Q)• Priority of less expensive solution(“costs”)
