Abstract
A method of managing electric energy consumption and/or production dynamics, includes the steps of: sampling an electric energy flow, adapted to be measured by an electricity metering device (1) within a network (15) of an electrical company; calculating a variation ΔEi=(Ei−Ei−1)/Δt at regular intervals, where Ei and Ei−1 are two integral sum values of electric energy amounts consolidated over a given number of cycles and Δt represents a time interval between the respective times at which the two values are obtained; adding the variation (ΔEi) to analogous variations calculated at previous times, to obtain a cumulative sum of such variations; determining whether the variation and/or the cumulative sum exceed a predetermined threshold value (δDE); transmitting a message over the network (15) from the electricity metering device (1) if the variation and/or cumulative sum exceed the predetermined threshold value (δDE).
