Title: Smart Grids, Super Grids

  • Smart Grids, Super Grids
  • Myth or Reality ?
  • by André MERLIN
  • President CIGRE MEDGRID
  • President Supervisory Board RTE ERDF

Contents
  • New requirements of power systems within the
    European Energy Policy
  • Smart Grids and Super Grids stakes and
    applications in transmission and distribution
    systems

Electricity will play a more and more important
role to meet the three main objectives of the
European Energy Policy
  • To increase the security of supply
  • To reduce CO2 emissions
  • To control energy costs.

  • On the demand side, electricity provides high
    level energy efficiency
  • On the supply side, it provides for the
    development of low carbon energy sources (from
    nuclear, hydraulic, wind, solar, geothermal).

Power generation for EU-27 by 2020
  • 2/3 of the production from low carbon sources
  • 1/3 nuclear
  • 1/3 renewable sources (including hydraulic)
  • of which 13 wind energy (1.9 in 2005).

6
7
13 wind energy in the electricity mix in 2020
implies a production of 500 TWh out of a total
of 4 000 TWh
  • In order to produce such a quantity, 200 to 250
    GW wind farms out of a total of 1000 GW power
    plants, must be installed and connected to the
    European power system.

Looking ahead to 2050
  • When CO2 capture and sequestration (CCS)
    technology is industrially available, it will be
    possible to design a European power system with
    nearly no CO2 emissions.

8

  • SUCH A RADICAL CHANGE IN THE MIX OF POWER
    GENERATION WILL REQUIRE A GREAT EVOLUTION OF THE
    GRIDS.

9
10
Why such a change ?
  • To allow for the large integration of
    intermittent renewable energies
  • To increase the security of supply by mutual back
    up between the power systems of the Member States
    of the EU and with the neighbouring
    interconnected regions
  • To reach a wider integration of the electricity
    markets.

10
11
What does this mean for the future of the grids ?
  • Stonger interconnections within the European
    system
  • An extension of these interconnections beyond the
    present limits (to the South around and across
    the Mediterranean Sea and with the Russian
    electricity system UPS/IPS)
  • A more efficient operation of the electricity
    systems and particularly the distribution
    networks to face the growing complexity of
    systems management.

11
12
Two major strategies for future electricity
systems
  • More powerful networks (Super Grids)
  • More intelligent networks (Smart Grids)

12
13
Super Grids 4 priorities for the development of
the electricity transmission system of the EU
  • An interconnection plan for Baltic networks with
    the European electricity network
  • A Euro-mediterrannean interconnection plan
    (MEDGRID)
  • A Centre - South - East Europe interconnection
    plan
  • An interconnection plan for an offshore submarine
    network in the Baltic and North Sea.
  • Second EU strategic energy review by the
    European Commission (November 2008)

Submarine grid for the North Sea and the Baltic
Sea
By 2020, connect 25 GW of wind farms and
hydraulic plants to the National AC systems in a
first phase and benefit from trading
opportunities.

Regional study centre for coordinated operation
of the system, Coreso is a partnership of RTE,
Elia, National Grid, Terna and 50Herz which aims
to evaluate the safety of the Western system, to
inform and to alert the National dispatchings.

CECRE (Red Electrica) First control room for
renewable energies
  • Provides for maximum integration of renewable
    sources within the electricity system in the
    safest conditions.

Smart Grids Distribution Networks
  • The opening of electricity markets has led to
    the development of the smart meter which is the
    cornerstone of Smart Grids in the distribution
    network.
  • The European Commission targets 80 of smart
    meters in 2020.
  • The network is changing from passive to active
    through the development of decentralized power
    generation from wind or solar installations and
    its structure and operation must be quickly
    adapted.

market Directive of the13 July 2009

  • The  communicating meter  the lever of
    modernisation for the management of ERDF
    distribution networks
  • Improve the knowledge of the network by having
    data more precise and updated real time
  • Better charge of the customers consumption
  • Allow demand side management toreduce energy
    consumption
