Abstract
Abstract This power adjustment device for electric power systems, in particular for electric power systems with electric ovens, has the aim of optimizing the electric absorption of the system by reorganizing the power requests of the various users comprised in the system. The device comprises elements for detecting the power requests of a plurality of users, a control and management unit adapted to check if the available power is sufficient to feed the requesting users and to enable and disable selectively some of the users operating at that moment according to the available power and according to criteria of priority or of elapsed operating time.
