“Europe 2020 is the EU's growth strategy for the coming decade.

In a changing world, we want the EU to become a smart,

sustainable and inclusive economy. These three mutually reinforcing priorities should help the EU and the Member States

deliver high levels of employment, productivity and social cohesion”

José Manuel Barroso

President of the European Commission

Where it all began… A smarter way of thinking



The 20-20-20 targets represent an integrated approach to climate and energypolicy that aims to combat climate change, increase the EU’s energy security

and strengthen its competitiveness:

A 20% reduction in EU greenhouse gas emissions

Raising the share of EU energy consumption

produced from renewable resources to 20%

A 20% improvement in the EU energy efficiency

To achieve the 20-20-20 goal it is necessary to ensure sustainability, safety and

competitiveness.

Existing power networks must evolve and become “smart”.

EU's Climate/Energy objectives for 2020



Evolution driven by new needs

EU first started to move towards the growth in production from renewablesources, encouraging every Member State to adopt specific legislation to

promote energy production from wind power, solar plant, hydroelectric and

biomass.

In Italy the growth hasconcerned mainly wind

power and solar plant



Characteristics of renewable power plants

Wind Power typically large installation of relevant power, both on-shoreand off-shore, mainly connected directly to HV transmission grid

Solar Plant from very low to medium power size, mainly connected to

LV network (residential and small size industrial plants) and MV

distribution grid (large photovoltaic plants)

Growing of production on LV and MV side of the electrical network has

highlighted a new issue to face Distributed Generation

The grid is becoming active the usual energy flow characterizing passive

network no longer applies:

GENERATION TRANSMISSION DISTRIBUTION END USER



TRADITIONAL NETWORKS

Centralized control suitable for

passive network

One-way energy flows

Limited interaction between

control centers and peripheral

nodes

Fixed base trading of energy

market

SMART GRIDS

Distributed control of the

equipment in an active network

Bidirectional energy flows

Full interaction with loads,

distributed generation, storage

systems

Demand-Response policy in real-

time energy market

The scenario is evolving…



… how reacting?

Power grid operators, especially Distribution System Operator, has twopossibilities to approach and face this issue:

Large investments in infrastructure to upgrade the grid and guarantee

reliability and security of energy supply

Using innovative and “smart” technology in order to compensate the

deficits of an “old” paradigm and preserve network assets

Obviously, the second one is the only cost effective way to reach the goal

ensuring grid stability



Communication system allowing the efficient and real-time exchange of huge

data flows

Supervision system enabling new functionalities (voltage and frequency

regulation, self healing capabilities,…)

Automation, monitoring and control systems ensuring the supply of

power in a constant and reliable way

Main features of a Smart Grid



Selta: the “smart” choice

SELTA is the ideal partner for utilities that want to approach smart paradigm,

thanks to its relevant know-how covering several fields:

automation of HV/MV stations, with control, monitoring and protection

equipment compliant with the IEC 61850 and IEC 61131-3 standards

remote control, protection and regulation for transmission substations,

distribution substations and end users’ power plants

SCADA and Distribution Management Systems

Automation, monitoring, control



SELTA communication solutions ensure capillarity, excellence in performance,

reliability and information security using different kinds of communication

means, such as:

“Access” equipment for cable and fiber optic (flexible multiplexers, DSLmodems, bonding terminals)

Solutions leaning on Wi-Max, as well as 3G and LTE mobile networks

Power line carrier (PLC) transmission systems for HV and MV power lines

Selta: the “smart” choice Communication systems



Pilot projects and funded experimentations

Grid4EU – “Increase the MV network’s hosting capacity for DER, introducingactive control and demand response of MV generators, controllable loads and

storage”: project funded by the EU FP7 committee (the Seventh Framework

Program for EU Research), coordinated by ERDF (France) and managed by

Enel (Italy) regarding technical choices

POI-P3 – improvement of the distribution network according to the SmartGrid principles, carried by Enel Distribuzione, italian DSO

ASSEM – experimental project funded by the AEEG (Energy and Gas

Authority) for studying and developing new active MV network for multiutility

company located in San Severino Marche (Italy)

Deval – experimental project funded by the AEEG (Energy and Gas Authority)

for studying and developing new active MV network for multiutility company

operating in Valle d’Aosta (Italy)

DG Distributed Generation (Active User side of Substation)

DS Distribution Substation (MV)



Main functions for ASSEM MV network

When a earth fault occurs the line protection on the top of the feeder keeps

the breaker closed, thanks to Petersen coil supporting the fault current

Fault detector systems sense the direction of the current, share the value

between neighboring devices, and find the origin of the fault

The portion of the grid affected by the fault is automatically isolated

Short Circuit fault can be managed as well, thanks to the boost in

communication process given by Goose messaging (61850)
