A guideline to link the off-design performance of a micro-gas turbine to a heavy-duty gas turbine in a test rig that aim to investigate flexibility of GTCC

In the era of coal power station phase-out, natural gas fired combined cycle will drive energy transition towards sustainable generation. a panorama strong requirement for grid flexibility and non-dispatchable renewable penetration, survival thermal plant is strictly linked with operating successfully in compensating fluctuating production through flexible The Italian case taken as reference, considering that penetration may have similar effects also different countries. this direction, test rig to investigate turbine compressor inlet conditioning techniques has been developed at Tirreno Power laboratory University Genoa, Italy. This based on Turbec T100 micro (or microturbine), Mayekawa heat pump phase-change material storage. whole test-rig virtually scaled up, cyber-physical system, emulate real 400MW cycle, governing conditions compressor. microturbine therefore used physical feedback whilst steam bottoming simulated real-time according operation. scope present procedure adopted scaleup heavy-duty GT. advantage using testing options lays possibility make accelerated tests simulate multiple situations compressed time windows.
