Dynamic Modeling and Simulation of a Hybrid Fuel Cell/Gas Turbine Power Plant for Control System Development

This paper presents dynamic modeling and simulation results for a Fuel Cell/Turbine Hybrid Power System and describes the overall use of modeling/simulation as a tool in the design of advanced controllers for Fuel Cell/Turbine systems. The simulation includes representation of the fuel cell stack integrated with balance-of-plant, including microturbine generator and heat recovery. A conventional control system based on PID controllers is also represented. Motivation for this work is to help sustain and enhance commercial viability of hybrid systems by operating them at maximum possible reliability, efficiency, and load range.Copyright © 2004 by ASME
