Modelling, simulation, identification, and model-based control of integrated fuel-cell-based power plants

摘要

In this contribution, a fuel cell-based power plant which uses water and methane to produce electrical power is considered. While earlier publications deal with the fuel cell only, this contribution takes the whole plant into account. The distributed modelling of the hydrogen producing reformer unit is presented. Methods are developed which allow for a fast and efficient simulation of the model equations. As the other parts of the power plant are of similar dynamical structure, the simulation methods are easily transferable. The identification of parameters for the power plant is performed on the basis of measurements and dynamic simulation. Sophisticated control concepts for the optimal operation of the power plant are proposed. They consider the whole plant and couplings between the various elements to maximise the plant's efficiency.
