Smoothing of a load curve comprising aggregation of elementary load curves

A system for managing and/or monitoring load consumption, able to determine an overall load curve comprising aggregation of a plurality of elementary load curves, each elementary load curve corresponding to a temporal variation of the consumption of a periodically regulated load i, said system comprising:

• means for smoothing said load curve by applying the steps of:
• determining a regulation period di associated with the corresponding load i;
• determining and storing each elementary load curve by obtaining a plurality of measured consumption samples with a sampling period Tech that is a submultiple of each regulation period di;
• starting from a reference time to common to all of the loads, time-shifting either the operation of each load i or at least part of each stored elementary load curve by a random shift Δti depending on the sampling period Tech, on the regulation period di determined for the load i and on a random integer value Ni associated with the load i.
