A method for determining individual fuel consumption characteristics of different generator units of an electricity generating assembly, includes an acquisition of operation data including, for several acquisition times, a measurement of a total fuel flow rate consumed by the generating assembly, and measurements of the respective load rates of the different generator units, and a determination of the individual fuel consumption characteristics of these different generator units, from these acquired operation data.

A method for determining a sequence of operation of at least one set of generator units of an electrical network includes assigning a rank to each generator unit; from a projected load curve, determining a minimum number of generator units; for each generator unit having a rank less than or equal to the minimum number of generator units, allocating in the sequence of operation the on state to the generator unit for each time interval; for each generator unit having a rank greater than the minimum number of generator units, allocating, by increasing rank, for each time interval of the sequence of operation the on state or the off state to the generator unit, and for each generator unit to which is assigned the on state at a given time interval of the sequence of operation, allocating an operating power, by optimisation of a cost function over a period.

A method for detecting a fault in a photovoltaic module includes determining a matrix of temperatures of the photovoltaic module, the matrix being obtained after dividing the module into a plurality of thermal zones and assigning a temperature to each thermal zone; detecting at least one hot thermal zone from among the plurality of zones of the module; determining a surface area ratio between the surface area of the detected hot thermal zone and the total surface area of the module; performing a first comparison of the surface area ratio with a coefficient dependent on the number of bypass diodes present in the module; and determining the type of fault from the result obtained in said first comparison.
