“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”
Where it all began…A smarter way of thinking
October 15, 2014 Stefano Zanin - Marketing
José Manuel BarrosoFormer President of the European Commission
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 andstrengthen its competitiveness:
EU Climate-Energy objectives for 2020
October 15, 2014 Stefano Zanin - Marketing
• 20% reduction in EU greenhouse gas emissions
• 20% of EU energy consumption from renewable resources
• 20% improvement in the EU energy efficiency
To achieve the 20-20-20 goal it is necessary to ensure sustainability, safety andcompetitiveness.
Existing power networks must evolve and become “smart”.
Evolution towards “greener” sources
EU first started to move towards the growth in production from renewablesources, encouraging every Member State to adopt specific legislation topromote energy production from wind power, solar plant, hydroelectric andbiomass.
In Italy the growth has concerned mainly wind powerand solar plant total amount of installed energy is about 20%of total installed production capacity but could theoretically cover almost 40% national demand in electric power
October 15, 2014 Stefano Zanin - Marketing
Overview of current Italian situation

Characteristics of renewable power plants
• Wind Power: typically large installation of relevant power, both on-shore andoff-shore, mainly connected directly to HV transmission grid
• Solar Plant: from very low to medium power size, mainly connected to LVnetwork (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 hashighlighted a new issue to face Distributed Generation

The scenario is evolving…
October 15, 2014 Stefano Zanin - Marketing
Traditional Network
• Centralized control suitable for passive network
• One-way energy flows, passive Grid
• Limited interaction between control centers and peripheral nodes
• Fixed base trading of energy market
Smart Grid
• Distributed control of the equipment in an active network
• Bidirectional energy flows, active Grid
• Full interaction with loads, distributed generation, storage systems
• Demand-Response policy in real-time energy market
… 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 goalensuring grid stability…
October 15, 2014 Stefano Zanin - Marketing
• Communication system “always on”, real-time communication, data frame
• Supervision system enabling new functionalities
• Protection and control IED ensuring the supply of power in a reliable way
Main features of a Smart Grid
October 15, 2014 Stefano Zanin - Marketing

Main functions for ASSEM MV network
• When a earth fault occurs the line protection on the top of the feeder keepsthe 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 61850 Goose messaging
