Integrated model framework for the evaluation of an SOFC/GT system as a centralized power source

Abstract

SUMMARYNew power generation technologies are expected to reduce various environmental impacts of providing electricity to urban regions for some investment cost. Determining which power generation technologies are most suitable for meeting the demand of a particular region requires analysis of tradeoffs between costs and environmental impacts. Models simulating different power generation technologies can help quantify these tradeoffs. An Internet-based modelling infrastructure called DOME (distributed object-based modelling environment) provides a flexible mechanism to create integrated models from independent simulation models for different power generation technologies. As new technologies appear, corresponding simulation models can readily be added to the integrated model. DOME was used to combine a simulation model for hybrid SOFC (solid oxide fuel cell) and gas turbine system with a power generation capacity and dispatch optimization model. The integrated models were used to evaluate the effectiveness of the system as a centralized power source for meeting the power demand in Japan. Evaluation results indicate that a hybrid system using micro-tube SOFC may reduce CO 2 emissions from power generation in Japan by about 50%.

Thermodynamic modeling of direct internal reforming solid oxide fuel cells operating with syngas

“…Most of the studies in the literature investigate the opportunities of integration of SOFCs with gas turbine cycles [12][13][14]. Integration of SOFCs with gasification cycles [15][16][17] is another promising option.…”

Greenhouse Gas and Air Pollutant Emission Reduction Potentials of Renewable Energy—Case Studies on Photovoltaic and Wind Power Introduction Considering Interactions among Technologies in Taiwan

“…This is because they could disregard the differences in the availability of renewable energy in spring and autumn because PV was the only renewable energy evaluated. 6,7 In this study, considering the Taiwanese wind speed characteristic (i.e., the wind blows mostly in winter to spring), spring and autumn are distinguished although the load patterns are similar to each other. To summarize, in addition to the differences in the regional climate, the evaluated renewable energy technology could influence the way the hourly load curve is modeled in a year.…”

“…The evaluation of power mix changes induced by the introduction of power technology in the future was conducted by Koyama,6 who estimated the reduction potentials of a stationary solid oxide fuel cell/gas turbine (SOFC/GT) hybrid system and examined how various technical options affect such results. Fukushima 7 extended this approach to assess the consequences of SOFC/GT technology development considering technology breakthrough, materials requirement, and interaction with other emerging technologies.…”

A collaborative platform for sustainable building design based on model integration over the internet

“…This model, which is implemented using Mathwork's Matlab, calculates the temporal distribution of centralised power generation dispatch to different power generation options that gives minimum cost together with the power generation installation or expansion costs and operation costs for a given temporal demand profile (Kraines et al, 2002;Xia et al, 2004;Koyama et al, 2004). These calculations are made by solving a linear programming problem subject to technical parameters of the different power generation types that are available for supplying electricity to the grid: nuclear, coal-fired thermal, liquefied natural gas-fired thermal, etc.…”
