Due to the intensive expansion of renewable energies, the technological and economic boundary conditions for conventional power plants in Germany changed significantly over the last few years. Nowadays the flexibility in power production becomes increasingly important. This development is caused by the fluctuating power output from renewable energies, such as wind power and photovoltaic. A similar trend can be expected in other European countries and even world wide, where the expansion of renewable energies is pursued to reduce the emission of carbon dioxide. Dynamic simulation models play a central role in improving the flexibility of power plants as they offer a tool for the evaluation of the resulting highly transient operation.
This paper presents the dynamic modeling of a steam power plant in Modelica/Dymola, using the power plant library ClaRa (Clausius Rankine). The focus is on the detailed non-steady-state modeling of the steam generator and a simulation study about the increase of the load change rate.
