Energy-reliability optimization of wind energy conversion systems by sliding mode control / Munteanu, I. in IEEE transactions on energy conversion, Vol. 23 n°3 (Septembre 2008) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 23 n°3 (Septembre 2008) . - pp. 975 - 985 Titre : Energy-reliability optimization of wind energy conversion systems by sliding mode control Type de document : texte imprimé Auteurs : Munteanu, I., Auteur ; Seddik Bacha, Auteur ; Bratcu, A.I., Auteur Année de publication : 2008 Article en page(s) : pp. 975 - 985 Note générale : Energy conversion Langues : Anglais (eng) Mots-clés : Power  generation  control;  power  generation  reliability;  torque  control;  variable  structure  systems;  wind  power;  wind  turbines Résumé : This paper describes a manner in which the energy-reliability optimization of wind energy conversion systemspsila operation can be achieved by means of the sliding mode control. The proposed approach aims at designing a tradeoff between maximizing the power harvested from wind by a horizontal-axis-grid-connected variable-speed doubly-fed-induction-generator-based wind power system and minimizing its mechanical stress. An appropriate sliding surface has been found in the speed-power plane, which allows the operation more or less close to the optimal regimes characteristic. Thus, by torque controlling the generator, an energy-reliability optimization of the wind turbine behavior is performed. The proposed control law is validated by both off-line and real-time simulation; the latter on a dedicated experimental rig, based upon the hardware-in-the-loop simulation concept. The results show that the control objective is fully accomplished.

Hardware-in-the-loop-based simulator for a class of variable-speed wind energy conversion systems / Munteanu, I. in IEEE transactions on energy conversion, Vol. 25 N° 2 (Juin 2010) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 25 N° 2 (Juin 2010) . - pp. 564 - 576 Titre : Hardware-in-the-loop-based simulator for a class of variable-speed wind energy conversion systems : design and performance assessment Type de document : texte imprimé Auteurs : Munteanu, I., Auteur ; Bratcu, A.I., Auteur ; Seddik Bacha, Auteur Année de publication : 2010 Article en page(s) : pp. 564 - 576 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : machine  control;  permanent  magnet  generators;  power  grids;  rotors;  synchronous  generators;  wind  power Résumé : This paper focuses on the design, building, error evaluation, and performance assessment of a physical simulator for a variable-speed wind energy conversion system (WECS). Such simulator, dedicated to control algorithms validation, must replicate the dynamical behavior of the WECS physically in real time. To this end, software parts, which model subsystems of the plant, and hardware parts, taken as they are from the plant, are closed-loop connected, thus implementing a hardware-in-the-loop (HIL) simulator. The simulator interacts with a software-simulated environment-in this case, the wind velocity-in order to run experiments under controllable conditions. Controllers to be tested interact directly with the hardware part of the simulator, thus better approaching the behavior of the real-world WECS. A complete grid-connected generation chain employing a horizontal-axis fixed-pitch three-bladed rotor permanent-magnet-synchronous-generator-based WECS is chosen as example for the design and performance assessment of an HIL simulator, both in frequency and time domain.
