Wind Turbine Operation in Electric Power Systems

The total capacity of wind turbine generator systems (WTGSs) operating in the world reached 27 600 MW in Autumn 2002. Most of them were located in Germany (10 650 MW), Spain (4100 MW) and Denmark (2500 MW). The EU plan is to achieve a total capacity of WTGS of 60 000 MW by 2010 and 150 000 MW by 2020.
