CIGRE’s Role in the Dynamic Change of the Electric Power Sector

AORC meeting, Guangzhou, Sept. 3rd, 2013

Sufficient Supply of energy – a global problem

• Need for energy is increasing• Resources should be sustainable • Environmental (carbon) footprint should be as low as possible

• Energy supplyshould be available

for all people ataffordable prices


Electricity offers solutions

• Shift of the fuel mix towards sustainable sources:– Most efficient use of fossil fuels– Renewable generation(hydro,wind,PV,etc.)– Electrification of consumers which used to burn fossil fuel (transport, heat pumps)

– Increase of consumers efficiency

• Mass free ‐ transport and distribution of energy

increase of overall energy efficiency


Key Problems• Fast expansion of the system needed in many countries

• Increasing intermittency of generation on all voltage levels

• Fading acceptance of infrastructure by people in many countries

• Rights of Way (ROW) difficult to achieve • Subsidized solar energy competes with conventional peak power production new investment of gas/pumpstorage becomes difficult


High capacity transportfrom remote areas

Intermittancy needs greater installed capacity and/or

storage and greater interconnection

New consumers and millions of small producers require complex and intelligent

system architecture ("smart grid")

An adequate Transmission and Distribution system is crucial


1000 kV lineChina

Examples

•China: 1000 kV AC supergrid800 kV DC

•Russia: Grid upgrading

•Brazil: 765 kV AC, 800 kV DC

•India 1200 kV AC, (pilot project running)

•USA 765 kV supergrid(planned)

•Europe ? HVDC Grid ?

The Vision of a Global Grid


Technology is available

• Intelligent and compact substation design(control, visibility, offshore, easy transport)

• Compact/ high capacity overhead lines• UHV 1100 kV AC• Polymer Cables up to 550 kV• HVDC up to 800 kV (1100 kV)?• Powerful ICT Tools

(Automation, Control, Simulation, Smart Metering, Cyber Security)

• Microgrids


Long Distance Transmission by HVDC:

• Standard +/- 500 kV• China / India +/- 800 kV (+/- 1100 kV dc)

•Line commutated converters, up to 6500 MW, •Thyristors

•Voltage source converters/multi level converters

up to 1200 MW with cableup 2400 MW with OHL


The Smart Grid Evolution


Key Technologies still needed (examples)

• Polymer cables/GIL for HVDC higher than 300 kV• HVDC switchgear / HVDC grids• Submarine Cables for great depth• Economic Electric energy storage at all voltage levels
