Abstract: In this article, the performance of a micro gas turbine (mGT) and a supercritical CO2 (sCO2) system fuelled by a biomass gasifier and with similar nominal net power output is compared. Both plants include a bottoming organic Rankine cycle system to maximise the electrical power output. Using a component-oriented, off-design modelling approach a sensitivity analysis is performed by varying the main operating parameters. In addition, the integrated systems are also evaluated in combination with a network of residential apartments to assess their adaptability to variable users' thermal and electrical demands.
