Modeling and Analysis of Transport Processes and Efficiency of Combined SOFC and PEMFC Systems
Rabbani, Abid; Rokni, Masoud - In: Energies 7 (2014) 9, pp. 5502-5522
A hybrid fuel cell system (~10 kWe) for an average family house including heating is proposed. The investigated system comprises a Solid Oxide Fuel Cell (SOFC) on top of a Polymer Electrolyte Fuel Cell (PEFC). Hydrogen produced from the off-gases of the SOFC can be fed directly to the PEFC....

Harmonic Injection-Based Power Fluctuation Control of Three-Phase PV Systems under Unbalanced Grid Voltage Conditions
Zhou, Nian-Cheng; Lou, Xiao-Xuan; Yu, David; Wang, … - In: Energies 8 (2015) 2, pp. 1390-1405
Unbalanced voltage will inevitably cause power and DC voltage fluctuations in a three-phase PV system. The deterioration of power quality will do great harm to the PV panels and the loads, so it is necessary to suppress the power fluctuations. This paper further explores the coefficients control...
