Abstract : One of the most common methods, to resolve the energy crisis, is utilizing renewable and clean
fuels. Continuously, the presentation of the multi-generation systems has been a great revolution in the energy
field through the increment of the total efficiency of the energy systems. In this study, an integrated energy
system,includingsolid oxide fuel cell (SOFC), gas turbine (GT), and multi-effect distillation (MED)unitswas
simulated, by the Aspen plus software,in order to produce200 kW net electrical power and desalinated water.
The hydrogen,used by the SOFC plant, was produced by the methanol reforming process, in a reformer, which
heated up to 260 °C by solar energy. Parabolic dish collector was applied to absorb the solar irradiation.
Buraydah city, in Al-Qassim region,Saudi Arabia was selected to study,and A dish collector was designed by
MATLAB software, based on the maximum available solar direct irradiation, which was equal to 815 W/
m2.The energy and exergy efficiencies of the SOFC/GT integrated system were obtained as 44.5% and 62.4%,
respectively.Integrating the an MED plant with the SOFC/GT increased the totalexergy efficiency of the system
by 2%. Finally, the effect of fuel utilization and current density factorson the thermodynamic performance of the
proposed system was investigated through sensitivity analysis. Also, an appropriate model was proposed to
improvethe system performance.
Keywords - Integrated energy system;methanol reforming;parabolic dish collector;solid oxide fuel cell;
