Method, system and device for managing the consumption of electric energy in a domestic environment

Abstract

A method is described, for managing the energy consumption of electric users (LB, LS, FO, PG, CO), including household appliances, in a domestic environment (A), said users being operatively connected in a network (RE), each one of said users (LB, LS, FO, FG, CO) presenting an electric load to a source of electric energy, comprising the steps of: presetting an appropriate maximum limit of power (Pmax) which can be supplied by said source of electric energy, providing each user (LB, LS, FO, FG, CO) with control means for managing its own consumption of electric energy, measuring the instantaneous total consumption of the electric energy (Ply) supplied by said source to said domestic environment (A), transmitting to the control means of each one of said users (LB, LS, FO, FG, CO), by means of said network (RE), information relating to the instantaneous total consumption of the supplied electric energy (PIT), making the control means of each one of said users (LB, LS, FO, FG, CO) capable of adjusting the electric load being presented to said source of energy by the respective user in response to said information. According to the invention, said information relating the instantaneous total consumption of the electric energy (PT) is transmitted on said network (RE) with a frequency which is variable in function of: the value of the instantaneous total consumption of the absorbed electric energy (PT), measured by a measuring device (MP), and said maximum limit of available power (Pmax).
