Beschreibung
Zusammenfassung:	The method of the invention dynamically determines the optimal voltage set point for the on-load electrical tap changer (4) and the corresponding parameters of the automatic voltage regulator (3) so that they are in correspondence with each other, and generally comprises the following steps:- Obtaining (5) at least one variable and/or at least one parameter of an electrical network (6) comprising a high voltage side (7) and a low voltage side (8),- Generating (11) an electrical network model (6) and launching (12) a load flow or state estimate,- Calculating or estimating (13) voltage drops and load of electrical network lines (6),- Determining (14) the optimal voltage set point, and- Setting (10) the control policy followed by the automatic voltage regulator (3) that controls the on-load tap changer (4).
