Abstract :
Major technical issues related to increased reliance on distributed generation systems (DGS). In distribution systems including lack of: appropriate dynamic models reliable control approaches, efficient dispatch methods, and control strategies to facilitate the connection of distributed generation resources to distribution networks. Among available types of DGS, fuel cells show particular promise as they can operate on multiple fuels with low emissions, high efficiency, and high reliability. This paper presents a simplified dynamic model for SOFC. Moreover, constant-power and constant-current control strategies are modeled and analyzed through dynamic simulation of FC-grid interconnection. Dynamic limits of FC variables are considered presented model and unique electrical properties of PCs are discussed.
