Hierarchical cycles in the modern power system – exergy analysis under partial loads
TOMASZ KOWALCZYK, PAWEŁ ZIÓŁKOWSKI, SEBASTIAN KORNET

Abstract

The aim of this paper is to investigate thermodynamic efficiency of hierarchical thermodynamic cycles under partial loads by using of exergy analysis. Advanced hierarchical cycles are composed of few energy conversion systems, which can be powered by several different sources of energy jointly. This kind of cooperation gives opportunities to provide high efficient and clean conversion of fossil fuels to electricity. Moreover, power plant consisting of few traditional power system gives new possibilities of optimization under partial loads.
