Abstract

This article covers the use of supplementary firing in a gas-combined cycle power plant when high flexibility is requireddepending on the penetration of variable renewable energies and under different gas turbine loads. Process models weresimulated under different operating conditions with the software EBSILONrProfessional. Five main conditions were studiedfor the designed combined cycle: gas turbine part-load without supplementary firing, gas turbine full load with supplementaryfiring, the use of supplementary firing to overcome the effect of changing ambient conditions, part-load gas turbine performancewith supplementary firing technology and the use of supplementary firing in case of gas turbine shutdown.
