Microgrid dynamic performance improvement using a doubly fed induction wind generator / Shahabi, M. in IEEE transactions on energy conversion, Vol. 24 N°1 (Mars 2009) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 24 N°1 (Mars 2009) . - pp. 137 - 145 Titre : Microgrid dynamic performance improvement using a doubly fed induction wind generator Type de document : texte imprimé Auteurs : Shahabi, M., Auteur ; Haghifam, M.- R., Auteur ; Mohamadian, M., Auteur Année de publication : 2009 Article en page(s) : pp. 137 - 145 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Asynchronous  generators;  distributed  power  generation;  frequency  control;  power  grids;  voltage  control;  wind  power  plants Résumé : This paper describes a control approach applied on a doubly fed induction generator (DFIG) to provide both voltage and frequency regulation capabilities, and hence, an improvement in the dynamic behavior of a microgrid system. The microgrid system is assumed to be a portion of a medium voltage distribution feeder and is supplied by two distributed generation (DG) units, i.e., a gas-turbine synchronous generator and a variable-speed wind turbine with DFIG. A control approach algorithm is proposed for the DFIG unit to improve both voltage and primary frequency controls. Two distinct operation modes, i.e., grid-connected and islanding mode, are used in the proposed approach for proper transfer from normal to islanding operation. Case studies are simulated based on both planned and unplanned islanding scenarios to evaluate the performance of the control approach. The study results show that the proposed control approach for DGs in the microgrid increase the microgrid system's dynamic performance, reduce frequency changes, and improve bus voltages regulation during islanding and autonomous operations.

A new variable-speed wind energy conversion system using permanent-magnet synchronous generator and Z -source inverter / Dehghan S.M in IEEE transactions on energy conversion, Vol. 24 N° 3 (Septembre 2009) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 24 N° 3 (Septembre 2009) . - pp. 714 - 724 Titre : A new variable-speed wind energy conversion system using permanent-magnet synchronous generator and Z -source inverter Type de document : texte imprimé Auteurs : Dehghan S.M, Auteur ; Mohamadian, M., Auteur ; Varjani, A.Y, Auteur Année de publication : 2010 Article en page(s) : pp. 714 - 724 Note générale : Energy Conversion Langues : Anglais (eng) Mots-clés : Invertors--Permanent  magnet  generators--Power  conversion--Power  grids--Synchronous  generators--Voltage  control-Wind  power Résumé : With the growth of wind energy conversion systems (WECSs), various technologies are developed for them. Permanent-magnet synchronous generators (PMSGs) are used by these technologies due to special characteristics of PMSGs such as low weight and volume, high performance, and the elimination of the gearbox. In this paper, a new variable-speed WECS with a PMSG and Z-source inverter is proposed. Characteristics of Z-source inverter are used for maximum power tracking control and delivering power to the grid, simultaneously. Two control methods are proposed for delivering power to the grid: Capacitor voltage control and dc-link voltage control. Operation of system with these methods is compared from the viewpoint of power quality and total switching device power (TSDP). In addition, TSDP, current ripple of inductor, performance, and total harmonic distortion of grid current of proposed system is compared with traditional wind energy system with a boost converter.
