The invention is directed toward an electrical power control system (1) in an electrical power system, having: a power control unit (2) for setting electric state variables and/or parameters in a current conductor, to be controlled, of the electrical power system, having: means (3) for -detecting electric characteristic values (u1) of the current conductor; a function processor for applying a control function (F1(u1)) from a mathematical set of control functions to the electric characteristic values, and for determining controlled variables (y) for achieving the parameters; and coordination means for determining a control function (F1(u1)) from the set of control functions with the aid of operating states of the electrical power system. This system renders it possible to achieve a predictive tuned control of the electrical power control system which can also stabilize unusual operating states of the electrical power system.
