A mathematical model for the dynamic simulation of low size cogeneration gas turbines within smart microgrids

The paper describes the mathematical model that has been developed to simulate in off-design and transient conditions the operation of a 65 kWel cogeneration microturbine installed within a smart microgrid. The dynamic simulation model is characterized by a flexible architecture that permits to simulate other different size single-shaft microturbines. The paper reports the main equations of the model, focusing on the architecture of the simulator and the microturbine control system; furthermore the most significant results derived from the validation phase are reported too, referring to the microturbine installed in the Smart Polygeneration Microgrid of the Savona Campus at the University of Genoa in Italy.
