Abstract: The increasing share of fluctuating electricity feed-in is forcing conventional power plants to change load more frequently. This increases thermodynamic losses, which are to be reduced with measures to increase efficiency in transient plant operation. A Modelica-based simulation model was developed to carry out exergy analyses for the transient operation of power plants. It was found that measures such as control technology adjustments only slightly increase exergy efficiency, but that there is potential for improving transient operating modes.
