Thermoeconomic Analysis of Concentrated Solar Power Plants Based on Supercritical Power Cycles

Solar thermal power plants are an alternative for the future energy context, allowing a progressive decarbonisation of electricity production. One way to improve performance such is use supercritical CO2 cycles. This article focuses on solar plant with central receiver coupled partial cooling cycle, and it conducts comparative study from both economic perspective aim optimising configuration receiver. The design based radial configuration, absorber panels converging tower axis; compact structures through which pressurised gas circulates. different configurations analysed keep constant provided by while varying number their dimensions. results demonstrate existence optimal that maximises exergy efficiency subsystem, taking into account heliostat field optical efficiency. evolution generation cost follows similar trend efficiency, exhibiting minimum values when this at its maximum.
