A method is provided for determining the structure of an electricity transmission grid, including a power supply station including one or more feeders for supplying electrical power to a plurality of electricity consumers, the method including acquiring first data relating to the electrical power consumed by each consumer during various time intervals; acquiring second data relating to the electrical power delivered by each feeder during the various time intervals; generating a plurality of different classes of data; calculating a first selection criteria for each class of data; selecting a first set of classes of data from the classes generated; and determining connection parameters.

Method and system for determining the structure of an electricity transmission grid and associated computer program

In an electric network () which comprises an upstream supply () and at least two downstream outlets, the supply and the outlets are each provided with a sensor () for measuring an extensive electric quantity and each sensor conducts, in a synchronous way with the other sensors, a measurement of this quantity depending on a parameter. This method comprises at least N measurements of the value on the upstream supply and on each downstream outlet conducted for different values of the parameter p. Then, the relationship between the measurements is formalized, for each value of the parameter p with the equation:  A system with N equations and N unknowns is generated, the unknowns being the gains a, the system of equations is solved, by calculating each gain, and the gains are controlled. If all the gains are equal to 1, it is considered that no sensor has conducted a faulty measurement. If at least one of the gains is different from 1, it is considered that at least one sensor has conducted a faulty measurement.

Method for detecting a defective measurement of an extensive electrical quantity

A method detects at least one photovoltaic electricity production apparatus in an electrical distribution network including at least one electrical installation and at least one current sensor, each installation further including at least one electrical apparatus. The method includes acquisition, by a current sensor, of a plurality of active power profiles of a corresponding installation, computation, for at least one pair of active power profiles of a differential profile equal to the difference between the power profiles of the pair, computation of a coefficient of correlation between the differential profile or profiles computed and a reference profile, and detection of the presence of a photovoltaic electricity production apparatus among the electrical apparatus or apparatuses of the installation.
