Solid oxide fuel cells (SOFCs) are modular and flexible in relation to the fuel in use, and have the capability to be used for combined heat and power applications at high efficiency. Due to the advantages, SOFCs are emerging as an attractive energy generation option. As a generation resource, SOFCs could be used as a distributed one connected with a large power system and also could be planted in...
Combining solid oxide fuel cell and gas turbine (SOFC/GT) system is a promising concept for future clean and efficient power generation. An SOFC/GT system exploits the complementary features of the two power plants, where the GT recuperates the energy in the SOFC exhaust stream and thereby boosting the overall system efficiency. Through model based transient analysis, however, it is shown that the...
Among different types of fuel cells, solid oxide fuel cells (SOFCs) show great potential applications due to many advantages such as low emission, high efficiency, and high power rating. On the other hand, SOFC systems are beneficial because they can convert fuel such as natural gas which is supplied by popular systems in many countries into electricity efficiently using internal reforming. In facts,...
This paper reports the study of dynamic behaviour of an integrated distributed generation (DG) system comprising wind turbines (WTs), solid-oxide fuel cell (SOFC) and microturbine (MT) under variable loading profile. WTs coupled to permanent magnet generators (PMGs) are combined with the SOFC and the MT to meet the total load demand. The fluctuations in the output of the WTs due to wind speed variations...
Solid oxide fuel cell (SOFC) is widely accepted for clean and distributed power generation use, but critical operation problems often occur when stand-alone fuel cell is directly connected to the electricity grid or the DC electric user. In order to address these problems, in this paper a data-driven fuzzy identification method is applied to the dynamic modeling of an integrated SOFC and capacitor...
