Public ISBD [article]  inIEEE 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  grids  voltage wind 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.
