METHOD AND DEVICE FOR MANAGING ELECTRIC ENERGY CONSUMPTION AND/OR PRODUCTION
First Claim
1. A method of managing electric energy consumption and/or production dynamics, comprising the steps of:
- sampling an electric energy flow, adapted to be measured by an electricity metering device belonging to a network of an electrical company;
calculating a variation Δ
Ei=(Ei−
Ei−
1)/Δ
t 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 Δ
t represents a time interval between the respective times at which said two values are obtained;
adding said variation (Δ
Ei) to analogous variations calculated at previous time instants, to obtain a cumulative sum of such variations;
determining whether said variation and/or said cumulative sum exceed a predetermined threshold value (δ
DE);
transmitting a message over said network from said electricity metering device if said variation and/or cumulative sum exceed said predetermined threshold value (δ
DE).

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).
