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
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.
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.
