Method for ensuring the safety of persons needing to service a low-voltage network of an electric power distribution system, wherein: the low-voltage network is connected to a substation supplying power to a plurality of dwellings within a geographical area, the dwellings are equipped with meters (C1,..., Cn) configured to measure and communicate consumption by regular time intervals, at least some of the dwellings are likely to comprise autonomous means of producing electricity (PV1,..., PVn) using renewable energy, a placing in operation of said autonomous means generating voltage in the low-voltage network despite shutting down the substation during the work, thus endangering people during their intervention, the method, implemented by a server communicating with the meters, being characterized in that it comprises the steps of: - obtaining first data from consumption records from each meter by regular time intervals, - obtaining second data which are meteorological data in the geographical area, in order to identify at least some weather conditions conducive to the production of energy by said autonomous means, - for each meter, applying a model for detecting, based on at least the first and second data, a coincidence between periods of low consumption measured by the meter and weather conditions conducive to electricity production by said autonomous means during said periods, and deducing, from the application of the model, information on the presence of autonomous means in the dwelling equipped with this meter, - for each dwelling, storing in a database the information on the presence of autonomous means, with a corresponding identifier specific to the dwelling, - and, before performing the servicing work, identifying in the database the dwellings likely to comprise autonomous means. the low-voltage network is connected to a substation supplying power to a plurality of dwellings within a geographical area, the dwellings are equipped with meters (C1,..., Cn) configured to measure and communicate consumption by regular time intervals, at least some of the dwellings are likely to comprise autonomous means of producing electricity (PV1,..., PVn) using renewable energy, a placing in operation of said autonomous means generating voltage in the low-voltage network despite shutting down the substation during the work, thus endangering people during their intervention, the method, implemented by a server communicating with the meters, being characterized in that it comprises the steps of: - obtaining first data from consumption records from each meter by regular time intervals, - obtaining second data which are meteorological data in the geographical area, in order to identify at least some weather conditions conducive to the production of energy by said autonomous means, - for each meter, applying a model for detecting, based on at least the first and second data, a coincidence between periods of low consumption measured by the meter and weather conditions conducive to electricity production by said autonomous means during said periods, and deducing, from the application of the model, information on the presence of autonomous means in the dwelling equipped with this meter, - for each dwelling, storing in a database the information on the presence of autonomous means, with a corresponding identifier specific to the dwelling, - and, before performing the servicing work, identifying in the database the dwellings likely to comprise autonomous means. - obtaining first data from consumption records from each meter by regular time intervals, - obtaining second data which are meteorological data in the geographical area, in order to identify at least some weather conditions conducive to the production of energy by said autonomous means, - for each meter, applying a model for detecting, based on at least the first and second data, a coincidence between periods of low consumption measured by the meter and weather conditions conducive to electricity production by said autonomous means during said periods, and deducing, from the application of the model, information on the presence of autonomous means in the dwelling equipped with this meter, - for each dwelling, storing in a database the information on the presence of autonomous means, with a corresponding identifier specific to the dwelling, - and, before performing the servicing work, identifying in the database the dwellings likely to comprise autonomous means.
