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.

CIGRE, 2015

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.

CIGRE, 2015

21

Fast economic growth requiring more and more power supply, and growing environmental awareness and requirements.

Manage the so called energy transition.

The challenges (2/8)

CIGRE, 2015

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.

CIGRE, 2015

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.

CIGRE, 2015

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.

CIGRE, 2015

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.

CIGRE, 2015

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

CIGRE, 2015

27

The challenges (8/8) Finally the last challenge is to manage the new

behavior of the consumers which can also be small producers.

CIGRE, 2015

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.

CIGRE, 2015

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.

CIGRE, 2015

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.

CIGRE, 2015

31

Available technologies (4/6)

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

CIGRE, 2015

32

Available technologies (5/6)

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

CIGRE, 2015

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.

CIGRE, 2015

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

CIGRE, 2015

35

Technologies to be developed (2/2)

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

levels.

CIGRE, 2015

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.
