Mejoramiento de la estabilidad de frecuencia de un sistema de generación eólica mediante la inclusión de inversores aplicando control robusto

Abstract

The objective of this scientific article is to improve the frequency stability in wind generation systems, by simulating a robust H-infinity control model to obtain a better control of the rotor speed, increasing the frequency stability of the wind system. A robust control of H-infinity is implemented since this controller provides a higher actuation response speed, allowing our system to be regulated as soon as possible. The control will be automatically in a minimum time that will act before the different levels of wind that occurs in the wind turbine, obtaining a reliable and safe system for users. Once the simulation was carried out, it was possible to demonstrate critical cases of studies where different frequency levels were applied, which are produced by the random behavior of wind generation, causing damage to the system where the perfect performance of the H-infinity control model could be observed. Finally, the results that are presented are obtaining a controlled frequency within the established limits and thus be able to have a quality electric power service.
