Governmental encouragement of renewable energies like wind energy led to an extensive increase of installed wind energy capacity worldwide. In order to allow a complete integration of this continuously fluctuating energy source; it is necessary to have a highly flexible operation management as well as power stations which are able to follow the high dynamics of the wind power production.
In this context the component fatigue and operational limitations of current and future power stations have to be investigated under the influence of enhanced plant dynamics.
For this purpose a detailed Modelica model of the hard coal fired steam power plant of Rostock; Germany is presented and extensively validated. The model makes use of the well-known non-commercial library ThermoPower. This Modelica Library is extended by models for common solid fuel burners and radiation-dominated firing zones. In addition to this; different approaches for modeling two-phase containers like the feed water tank are discussed. The derived model is used to compare different operation modes with respect to the occurring component wear.
