Abstract

Increasing the flexibility of conventional power plants is one key challenge for the transformationof the energy system towards a high share of renewable energies in power production. Flexible and dispatchable power plants fired by lignite, hard coal and natural gas will contribute during this ongoing transformation process as they compensate the intermittent power production from the renewable energy sources.

In this work, selected flexibility measures for hard‐coal‐fired power plants have been evaluated with regard to the achievable flexibilization and the thermodynamic effects on the power plant process. For this purpose, a dynamic power plant model has been built‐up using the Modelica library ClaRa in the simulation environment Dymola. The dynamic power plant model has been validated successfully against measurement data from the underlying reference power plant. The evaluation of flexibility measures first included the commonly proposed

options of the reduction of t...
