On-line identification of simplified CHP models

The main goal of this paper is to get a simplified equivalent dynamic model of a co-generator when it is operated in the grid-connected mode. The gas-fueled co-generator installed at the PrInCE Lab microgrid is adopted and modelled in the real-time as a dynamic model of the second order. Parameters of the proposed model are derived through an input-output identification methodology based on the Lyapunov Theorem applied to the Sensitivity Theory (LTST). The correctness of proposed model has been tested experimentally.
