In this study, a dynamic analysis model for integrated gasification fuel cell (IGFC) power generation was developed and the dynamic characteristics of electric power output by the system were investigated. Using the proposed analytical model, the study addressed the frequency deviation of electric power output, the inertia system of gas and steam turbines, the air fuel ratio of the solid oxide fuel cell (SOFC), and load patterns. Moreover, using the model, an example of an electric power load pattern in Japan was examined. Because the supply and demand difference in electric power can be monitored as frequency deviation in a power network, the frequency of each power generator was analyzed. Consequently, the output of IGFC gas and steam turbines could not be controlled in the target range. Therefore, it was necessary to stabilize the quantity of exhaust heat by improving the heat transfer speed of the SOFC. Copyright (C) 2015, Hydrogen Energy Publications, LLC.
