The described methods and systems may be applied to electric arc furnace installations. In this context, the method and system provide an electrode position controller coupled to the feed rate controller so as to predictively anticipate the introduction of new source material and lower the electrodes so as to prevent arc extinguishment while variable reactors are controlled to maintain predetermined power set-points. The electrode position controller may be used in place of, or in addition to, the variable reactance control system to take corrective action to address power and/or current changes or unbalances.
