An adaptive nonlinear controller for DFIM-based wind energy conversion systems / Mauricio, J.M. in IEEE transactions on energy conversion, Vol. 23 n°4 (Décembre 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°4 (Décembre 2008) . - pp. 1025 - 1035 Titre : An adaptive nonlinear controller for DFIM-based wind energy conversion systems Type de document : texte imprimé Auteurs : Mauricio, J.M., Auteur ; Leon, A. E., Auteur ; Gomez-Exposito, A., Auteur Année de publication : 2009 Article en page(s) : pp. 1025 - 1035 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Adaptive  control;  asynchronous  machines;  feedback;  linearisation  techniques;  machine  control;  nonlinear  control  systems;  observers;  parameter  estimation;  uncertain  systems;  wind  power Résumé : An adaptive nonlinear controller for wind energy doubly fed induction machines is introduced in this paper. The proposed controller is based on the feedback linearization technique and includes a disturbance observer for estimation of parameter uncertainties. Estimated uncertainties values are injected in order to construct the control law, improving in this way the system's performance. The controller behavior, when tracking power references, is tested with realistic electromagnetic transients for DC /power systems computer-aided design simulations. In addition, the controller performance is checked in the presence of parameter uncertainties and nearby faults.

An electrical approach to mechanical effort reduction in wind energy conversion systems / Mauricio, J.M. in IEEE transactions on energy conversion, Vol. 23 n°4 (Décembre 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°4 (Décembre 2008) . - pp. 1108 - 1110 Titre : An electrical approach to mechanical effort reduction in wind energy conversion systems Type de document : texte imprimé Auteurs : Mauricio, J.M., Auteur ; Leon, A. E., Auteur ; Gomez-Exposito, A., Auteur Année de publication : 2009 Article en page(s) : pp. 1108 - 1110 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Electric  generators;  machine  control;  power  generation  control;  wind  power  plants Résumé : A strategy for controlling wind farms composed of variable-speed machines is considered in this paper. It is shown that mechanical efforts produced by wind gusts on individual machines can be reduced by means of a supplementary control signal coming from a centralized controller. This is done while the total wind farm power output is kept at the same value as in the absence of the proposed controller.
