ABSTRACT
At present time the Wind Energy Converter Systems has a very promising and important role in the future of the Spanish electric generation. Spanish authorities has special projects to install in all regions of the country more than 15000 MW of wind power capacity in 2006. The integration of a significant amount of wind power will cause a serious impact on the efficiency, operation and control of the Spanish power system, which must be analised using sophisticated tools. In the Load Frequency Control, high wind power penetration expected into system generation mix may compromise the efficiency of operation of overall system, causing frequency variations and, even, the system might be lead to collapse. These variations must be efficiently compensated by generator regulators to avoid large frequency excursions. For the successfull control of frequency it is necessary to have accurate short-term forecast of wind power generation a few seconds to a few minutes ahead. Forecasts of wind power output are introduced in a regulator model of synchronous generator with the objective to reduce frequency variations in a power system.
