Smart Grid – The evolution of the future gridKarl Elfstadius, ABB Smart Grid

Smart Grid enables a change to a sustainable energy system

New political targets, with main focus on• Reduction of CO2 emission • Energy efficiency• Renewable power generation• Reliability and security

Consumption

Source: SvK

Production

Wind and Solar requires more balance power

Integration of renewable energy sourcesChallenge: Availability of emission free balance power

Smart Grid enables balance by increased transmission capacity and integrated active consumers

Smart Grid enables peak load shaving by active consumers

Use more efficient production units

Use less costly production units

Use units with less emission

Improved utilization of the grid capacity

More available balance power

New rules for the electricity market

Modified network regulation

Benefits for network operator and energy supplier

Develop business models that transfers part of the profit to the consumers

Smart Grid componentsHVDC Light – new technology for DC-connections

East West Interconnector 500MW

+- 200 kV cabel (sea & land)

Customer: Eirgrid, in service 2012
