MUNOZ, Eduardo; AYALA, Edy  e  POZO, Nicolás. Fuzzy PI Control Strategy to Doubly Fed Induction Wind Turbine for Power Maximization in Presence of Disturbances. Revista Técnica energía [online]. 2021, vol.18, n.1, pp.1-10. ISSN 2602-8492.  https://doi.org/10.37116/revistaenergia.v17.n2.2021.428.

This research proposes a control methodology applied to a Wind Power Generation Systems (WEGS) for Maximum Power Point Tracking (MPPT) technique based on a Fuzzy observer and complemented by a PI controller using the Direct Speed Control (DSC) method. This approach permits commanding the rotor side reference current through the variations of torque and electrical power in a Doubly Fed Induction Generator (DFIG) model. Consequently, the speed of the generator is controlled in order to obtain a rapid response of the maximum Power Coefficient (). The construction of this strategy starts with direct measurements of the electrical and mechanical variables using computational tools such as FAST and Matlab-Simulink for the wind turbine model simulations. This DSC strategy presents a rapid performance of the tracking considering the dynamics of a 1.5MW wind turbine and this strategy has been compared to a traditional PI controller improving the extraction of the output power.
