摘要： Disclosed are a hybrid power generation facility and a control method thereof. The hybrid power generation facility includes a gas turbine including a compressor configured to compress air introduced from an outside, a combustor configured to mix the compressed air with fuel and to combust the air and fuel mixture, and a turbine configured to produce power with first combustion gas discharged from the combustor, a GT (gas turbine) generator configured to generate electric power using a driving force generated by the gas turbine, a boiler including a combustion chamber and configured to mix the first combustion gas supplied from the turbine of the gas turbine with air and fuel supplied from the outside, a steam turbine through which steam generated in the combustion chamber passes, a ST (steam turbine) generator configured to generate electric power using a driving force generated by the steam turbine, and an energy storage system configured to be charged based on a decrease rate of power demand of a grid and a maximum decrease rate of power supply from the GT generator and the ST generator.

摘要： A supercritical CO2 generation system including a compressor configured to compress a working fluid; a first heat exchanger that exchanges heat with the working fluid passing through the compressor; a high temperature turbine that expands the working fluid passing through the first heat exchanger and connects to a power generator to produce power; a second heat exchanger that exchanges heat with the working fluid passing through the compressor; a low temperature turbine that expand the working fluid passing through the second heat exchanger and connects to the power generator to produce power; a third heat exchanger between the first heat exchanger and the high temperature turbine that exchanges heat with the working fluid recuperated by the first heat exchanger; and a cooler that cools the working fluid passing through the high temperature turbine and the low temperature turbine and supplies the cooled working fluid to the compressor.

摘要： A hybrid power generation system using a supercritical CO2 cycle includes a steam power generation unit including a plurality of turbines driven with steam heated using heat generated by a boiler to produce electric power, and a supercritical CO2 power generation unit including an S—CO2 heater for heating a supercritical CO2 fluid, a turbine driven by the supercritical CO2 fluid, a precooler for lowering a temperature of the supercritical CO2 fluid passing through the turbine, and a main compressor for pressurizing the supercritical CO2 fluid, so as to produce electric power. The steam power generation unit and the supercritical CO2 power generation unit share the boiler. The hybrid power generation system may improve both the power generation efficiencies of the steam cycle and the supercritical CO2 cycle by interconnecting the steam cycle and the supercritical CO2 cycle.
