Abstract: To ensure safety of people needing to service a low-voltage network of an electric power distribution system, dwellings being connected to this network may include autonomous units for producing electricity, thus generating voltage and endangering the people servicing the work. Data are obtained from consumption records from the meter of each dwelling, in regular time intervals, and meteorological data are also obtained in the geographical area of these dwellings, in order to identify at least some weather conditions conducive to the production of energy by autonomous units. A model is then applied for detecting, based on the first and second data, a coincidence between periods of lower consumption measured by a meter and weather conditions conducive to electricity production by autonomous units during these periods. Therefore, information on the presence of autonomous units in the dwelling can be deduced and given to people before their servicing.

Abstract: A device for estimating a deleted fluid consumption during a deletion phase, where said device comprises: a collection module configured to collect: a) first consumption data comprising information about the consumption of fluid from n fluid meters coming from a first group, and b) second consumption data comprising information about the consumption of fluid from m fluid meters coming from a second group, a computer analysis module which is configured for calculating, as a function of the first and second consumption data weighting coefficients ?i minimizing the distance between the fluid consumptions of the first and second groups, where i is a positive integer included between 1 and m.

Abstract: A computing system for predicting a curtailed consumption of fluid comprising: a module for collecting consumption data comprising information relating to an actual consumption of fluid of a plurality of consumers during a learning phase, a processing circuit for aggregating the consumption data collected by groups as a function of at least one determined descriptive variable associated with each consumer and contained in the consumption data, a processor for determining on the basis of the aggregated consumption data a curve of global load for each group, a computer for computing a model of extraction of a load curve, termed heating and/or air conditioning, on the basis of each global load curve and of meteorological data, and a predictor for computing a prediction of a curtailed consumption of fluid for each group during a forthcoming curtailment phase.
