Control and Simulation for Hybrid Solid Oxide Fuel Cell Power Systems

Abstract

Hybrid solid oxide fuel cell (SOFC)-gas turbine (GT) power system provides a promising solution for powering the future aircraft. This electrical power generation technology can achieve both the high efficiency and very low emission. However, two independent energy sources in the system, SOFC and GT, require more dedicated power management strategy. A novel power tracking control method is proposed in this paper to address the issue of power partitioning between two energy sources. In order to analysis and verify the control strategy in the hybrid SOFC system, a detailed system simulation platform is developed. The simulation results demonstrate that the power tracking control can effectively control the load power distribution between two channels.
