Abstract :
We describe methodologies for comprehensive
and reduced-order modeling of solid-oxide-fuel-cell (SOFC)
power-conditioning system (PCS) at the subsystem/component
and system levels to resolve the interactions among SOFC,
balance-of-plant subsystem, and power-electronics subsystem
(PES) and application loads (ALs). Using these models, we analyze
the impacts of electrical-feedback effects (e.g., ripple-current
dynamics and load transients) on the performance and reliability
of the SOFC. Subsequently, we investigate the effects of
harmonics in the current, drawn from the SOFC by a PES, on
the temperature and fuel utilization of the SOFC. We explore
the impacts of inverter space-vector modulation strategies on the
transient response, flow parameters, and current density of the
SOFC during load transients and demonstrate how these two traditionally
known superior modulation/control methodologies may
in fact have a negative effect on the performance and durability
of the SOFC unless carefully implemented. Further, we resolve
the impacts of the current drawn by the PES from the SOFC,
on its microcrack density and electrode/electrolyte degradation.
The comprehensive analytical models and interaction-analysis
methodologies and the results provided in this paper lead to an
improved understanding, and may yield realizations of cost-effective,
reliable, and optimal PESs, in particular, and SOFC PCSs, in general.
Index-Terms : Power-conditioning system (PCS), power-electronics subsystem (PES), solid-oxide-fuel-cell (SOFC).
