Large integration of wind power: the Spanish experience

There are over 11000 MW of installed wind power in the Spanish Electrical System. This amount of installed power, compared with a load peak around 43700 MW, has a big impact on system operation. The already collected real-time experience and the events experienced have created an interesting background for the integration of wind energy without jeopardising the actual levels of quality and allowing the achievement of the national and European environmental targets. This paper describes the actual situation of the integration of wind power in Spain and reports the experience and the developments put in place for a harmonized integration of wind energy.
