WHAT IS CIGRE?
Conseil International des Grands Réseaux
Électriques (International Council On Large
Electric Systems)

• Founded in Paris in 1921 as a worldwide

• CIGRE addresses issues related to the
  development, operation and management of electric
  power systems as well as design, construction,
  maintenance and disposal of equipment and plants.

3

• CIGRE aims to promote and organize collaboration
  with experts from all around the world, by
  sharing knowledge and joining forces to improve
  the electric power systems of today and tomorrow.

Power supply the CIGRE vision(a global issue)

• Our world is facing a global challenge to
  provide a sufficient and reliable supply of
  energy to the inhabitants of the Planet.
• On one hand the need for energy is increasing,
  and on the other hand the energy resources should
  be sustainable and their environmental footprint,
  essentially the CO2 emissions, should be as low
  as possible.
• Moreover the energy supply should be available
  for all people at affordable prices.

20
The challenges (1/8)

• Renewable energy sources using wind and solar
  energy are intermittent, and they have to be
  integrated on all the levels of the power
  systems, low and very high voltages.

21
The challenges (2/8)

• Fast economic growth requiring more and more
  power supply, and growing environmental awareness
  and requirements.
• Manage the so called energy transition.

22
The challenges (3/8)

• Rights of way to build new transmission
  infrastructures, the incentives given to
  renewable energy sources, the power balancing
  between countries and the need for energy
  storage.

23
The challenges (4/8)

• The distribution of electricity has to consider
  the connection of dispersed intermittent
  generation and the distribution network operators
  have to reconsider the architecture of their
  networks.

24
The challenges (5/8)

• The first challenge for operators is to keep the
  existing power systems with old infrastructures
  operating properly even if they have to face new
  problems due to the fast development of
  intermittent power sources.

25
The challenges (6/8)

• Another challenge is to transmit high amounts of
  power over longer distances to connect remote
  areas where the power is generated, towards the
  consumption areas.

26
The challenges (7/8)

• Intermittency of renewable power generation is a
  third challenge which requires more
  interconnection between areas or more energy
  storage.

2 weeks solar generation
2 weeks wind generation
27
The challenges (8/8)

• Finally the last challenge is to manage the new
  behavior of the consumers which can also be small
  producers.

28
Available technologies (1/6)

• Intelligent and compact substation design offers
  more controllability, more visibility, the
  possibility to build offshore networks, and make
  this equipment easy to transport.

29
Available technologies (2/6)

•  Compact and high capacity overhead lines are an
  answer to the need to increase the power in the
  existing corridors.

30
Available technologies (3/6)

•  Ultra high voltage equipment up to 1100 kV AC
  are available today to satisfy the needs for long
  transmission lines.

31
Available technologies (4/6)

•  Polymer cables are now available up to 550 kV to
  build underground or submarine links.

32
Available technologies (5/6)

•  HVDC is now used up to 800 KV and should be
  available soon for even higher voltages.

33
Available technologies (6/6)

•  Information and communication technologies
  provide adequate tools to satisfy the need for
  more automation, control, simulation, smart
  metering and cyber security.

34
Technologies to be developed (1/2)

• Polymer cables and Gas Insulated Lines for HVDC
  above 300 kV
• HVDC grids, requiring fast protection and DC
  circuit breakers

35
Technologies to be developed (2/2)

• Submarine cables for great depths
• Economic electric energy storage on all voltage
  levels.

36
The future power system

• The future of the power system is a challenge
  for engineers, scientists, economists and
  politicians equally.
• System planners and operators need new
  analytical tools and methods to model the
  increasing uncertainties.

37
The role of CIGRE

• Strategic directions
• Vision of the network of the future
• Organization of the works
