Abstract: A SOFC triple combined cycle power generation, consisting of a solid oxide fuel cell and gas turbine combined cycle is revealed to give efficiency improvement while reducing the amount of emissions in power generation. It comes from the fact that the exhaust heat generated from a cycle is further utilized for power generation in the next cycle. Studies concerning its designs and optimizations have been previously investigated, including the characteristics of the system. This study provides a model of a SOFC-TCC system aimed to provide a robust and appropriate load response while maintaining frequency deviation under normal conditions. The green hydrogen generated by PEMEC in the study is powered by the surplus renewable power where after generation, it is then stored in a hydrogen tank. The SOFC-TCC system in the study managed to provide power in response to power demand accurately without any substantial delay. Also, the observed frequency deviation throughout the whole cycle is under the tolerable amount.
