Voltage control and active power management of hybrid fuel-cell/energy-storage power conversion system under unbalanced voltage sag conditions / Hajizadeh, A. in IEEE transactions on energy conversion, Vol. 25, N° 4 (Décembre 2010) 

Public ISBD [article]  in IEEE transactions on energy conversion > Vol. 25, N° 4 (Décembre 2010) . - pp. 1195 - 1208 Titre : Voltage control and active power management of hybrid fuel-cell/energy-storage power conversion system under unbalanced voltage sag conditions Type de document : texte imprimé Auteurs : Hajizadeh, A., Auteur ; Golkar, M. A., Auteur ; Feliachi, A., Auteur Année de publication : 2011 Article en page(s) : pp. 1195 - 1208 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Distributed  power  generation;  electric  current  control;  energy  storage;  fuel  cell  power  plants;  hybrid  power  systems;  power  control;  power  conversion;  power  distribution  control;  power  supply  quality;  supercapacitors;  voltage  control Résumé : This paper concentrates on the control of hybrid fuel-cell (FC)/energy-storage distributed generation (DG) systems under voltage sag in distribution systems. The proposed control strategy makes hybrid DG system work properly when a voltage disturbance occurs in distribution system, and it stays connected to the main grid. To distribute the power between dc power sources and stabilize the dc-link power, a Lyapunov-based neuro-fuzzy control strategy has been developed. This controller determines the supercapacitor power that should be generated according to the amount of available energy in dc-link. Also, current control strategies for the FC converter (boost) and supercapacitor converter (buck-boost converter) are designed by proportional-integral and sliding-mode control consequently. Moreover, a complementary control strategy for voltage source converter based on positive and negative symmetrical components is presented to investigate the voltage sag ride-through and voltage control capability. The hybrid system is studied under unbalance voltage sag condition. Simulation results are given to show the overall system performance including active power control and voltage sag ride-through capability of the hybrid DG system.
