Integrating fuel cell/electrolyzer/ultracapacitor system into a stand-alone microhydro plant / Gyawali, N. 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. 1092 - 1101 Titre : Integrating fuel cell/electrolyzer/ultracapacitor system into a stand-alone microhydro plant Type de document : texte imprimé Auteurs : Gyawali, N., Auteur ; Ohsawa, Y., Auteur Année de publication : 2011 Article en page(s) : pp. 1092 - 1101 Note générale : energy conversion Langues : Anglais (eng) Mots-clés : Fuel  cells;  hydroelectric  power  stations;  supercapacitors Résumé : This paper explores the control and operational aspects of introducing fuel cell/electrolyzer/ultracapacitor (FC/ELZ/UC) unit into a microhydro power system, replacing the conventional electronic load controller/dump-load unit. FC/ELZ is expected to provide long-term energy balance by utilizing the hydrogen technology, whereas the UC is employed as buffer storage for the transient compensation. System configuration is proposed, control scheme is designed, and the detailed dynamic modeling is developed for each component of the system. Expected behaviors during the sudden load change and hydro input variation are observed by mathematical simulation. Finally, the results of the analysis are summarized with their applicability to real system and the limitation/further scope are indicated.
