Among renewable energy sources wind energy is having an increasing influence on the supply of energy power. However wind energy is not a stationary power, depending on the fluctuations of the wind, so that is necessary to cope with these fluctuations that may cause problems the electricity grid stability. The ability to predict short-term wind speed and consequent production patterns becomes critical for the all the operators of wind energy.This paper studies several configurations of Artificial Neural Networks (ANN), a well-knowntool able to estimate wind speed starting from measured data. The presented ANNs, t havebeen tested through data gathered in the area of Trapani (Sicily). Different models have beenstudied in order to determine the best architecture, minimizing statistical error. Simulation results show that the estimated values of wind speed are in good accord with the values measured by the anemometers.
