Abstract [en]

This paper discusses the load following capabilityof fuel cell-driven power plants. A linear model of a Solid OxideFuel Cell power plant is obtained and utilized for the designof robust controllers which enhance tracking response of theplant and reject disturbances originating from the distributiongrid. Two robust controllers are synthesized applying the Hmixed-sensitivity optimization and their performance is validatedby means of nonlinear time-domain simulations. The obtainedresults indicate that the disturbances can be successfully attenuated;however, the tracking response annot be signiscantlyimproved without a modification of the design of the fuel cellpower plant. The paper is concluded by a brief discussion onthe physical Limitations on the fuel cell output power ramp andpossible solutions are outlined.
