The Hammerstein model configuration, which includes a nonlinear static block followed by a linear dynamic block, is applied to model the static and dynamic characteristics of a micro-turbine. The parameters in the model can be extracted from the measurements of physical engines or from the simulations of physics-based models. In this paper, a nonlinear model is used to assist in the dynamic performance of the micro-turbine when connected to the grid as a distributed generator. Copyright (c) 2005 John Wiley & Sons, Ltd.
