Integrated solar combined cycle (ISCC) systems coupled with direct steam generation (DSG) are more promising in terms of system efficiency and electricity cost than current solaronly power generation systems, as ISCC–DSG offers the advantages of higher net thermal efficiency and lower costThus, on a plant level, a cogeneration combined cycle can have 1) operational flexibility, as given by the minimum load level, ramp rate and cycling characteristics of the plant [10]; and 2) product flexibility, by regulating the steam flow in the steam cycle to vary the ratio of district heating, electricity and/or other products (eg Flexible operation of a combined cycle cogeneration plant A

The world’s first combinedcycle power plant, a 75 MW facility in Austria, started operation in 1961 By the time of its retirement in 1974, and thanks to combined cycle efficiency improvements, NGCC had established itself as “the most efficient and lowcost route to electricity production,” according to an article in International Turbomachinery The steam tables show that the enthalpy of the turbine inlet steam is 14741 Btu per pound of fluid (Btu/lbm) Thermodynamic calculations based on a 10% increase in entropy indicate that the exiting enthalpy from the turbine is 9150 Btu/lbm (steam quality is 80%) Thus, 14741 9150 (= 5591) Btu/lbm of energy is converted to Steam vs CombinedCycle vs Cogeneration: Understanding the
