Dynamic interactions between power plants and power systems

This survey is focussed on the numerous dynamic interactions between power plants and power system. At the example of two applications there is shown the advantages of model-based power control concepts for steam power plants, being robust against internal power plant disturbances and external power system disturbances not only during normal interconnected grid operation but also in the cases of isolated grid conditions, and the influences of steam and hydro power plants as well as of the frequency dependent load on the damping behavior of slow interarea power system oscillations. Finally essential control tasks are assorted, belonging to power plants as well as to power system. Copyright (C) 1998 IFAC.
