Zusammenfassung:	In a method for operating an arc furnace (30) and a smelting system operated according to said method, at least one measurement value (M1) of a measurement variable characterizing the operating state of each of a plurality of system components that influence the operating conditions of the arc furnace (30) is detected and compared to a respective currently permissible threshold value for said measurement variable, and a maximum power (P) that can be supplied to the arc furnace (30) within a time window ([increment]t1) while satisfying all currently permissible threshold values is determined on the basis of the comparison result.
