  • Load Following Response of an SOFC Triple Combined Cycle System with Green Hydrogen Generation and Utilization Installed in Core Substations

抄録

<p>An SOFC triple combined cycle power generation, consists 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 investigated, including the load-following response of the SOFC- TCC system. The hydrogen fuel consumed will be provided by a hydrogen generation system of proton exchange membrane electrolyzer (PEMEC). The SOFC- TCC system is interconnected with a substation of renewable energy for green hydrogen prodcution, where surplus energy from the renewable is utilised to power the electrolyzer. The system shows adequate load-following response of G/T ans S/T. Whereas SOFC load-following response of SOFC needs to be improved for it directly affected the system’s frequency, specifically frequency deviation. The hydrogen generated by the PEMEC is insufficient to fuel the whole system which leads to consideration of other hydrogen generation and/or supply method.</p>
