Özet

Solid oxide fuel cell (SOFC) is being developed for a wide variety of applications because of their high efficiency, reliability, and fuel adaptability. In this paper, a grid connected SOFC system is presented by using PSCAD software. The power conditioning unit (PCU) is used for simulation studies and also the transformer is used for electrical isolation. The simulation studies of the SOFC dynamic model are investigated for three case studies. In the first simulation study, the SOFC dynamic model is connected to constant and variable DC loads without PCU. The second simulation study is performed for three phase AC load conditions. The AC performance of SOFC is tested under an AC load through the transmission line of 400V at the length of 10 km. The last simulation study is implemented for the grid connected SOFC system. In the grid connected case study, a three bus system, which includes an infinite bus, a load bus and a fuel cell bus, is formed under AC load conditions. The results show the fast response capabilities of the grid connected SOFC system in different case studies and various load types. (C) 2014 AIP Publishing LLC.

Solid oxide fuel cell (SOFC) is being developed for a wide variety of applications

because of their high efficiency, reliability, and fuel adaptability. In this paper, a

grid connected SOFC system is presented by using PSCAD software. The power

conditioning unit (PCU) is used for simulation studies and also the transformer is

used for electrical isolation. The simulation studies of the SOFC dynamic model

are investigated for three case studies. In the first simulation study, the SOFC

dynamic model is connected to constant and variable DC loads without PCU. The

second simulation study is performed for three phase AC load conditions. The AC

performance of SOFC is tested under an AC load through the transmission line of

400 V at the length of 10 km. The last simulation study is implemented for the grid

connected SOFC system. In the grid connected case study, a three bus system,

which includes an infinite bus, a load bus and a fuel cell bus, is formed under AC

load conditions. The results show the fast response capabilities of the grid

connected SOFC system in different case studies and various load types.
