Method for scheduling the operation of energy distribution devices, and installation implementing same

Abstract

The invention relates to a method for optimizing the supply of energy, over a time interval I of duration D, to an installation equipped with N energy distribution devices operating in all-or-nothing mode and by duration modulation, an operation duration Ai being allocated to each of the N energy distribution devices over the time interval I by a command/control system of the installation. According to the method: a schedule is defined over the time interval I by means of the time division of the set of operating sequences of the N energy distribution devices (B, B. . . BN), and the schedule is calculated before the start of the time interval I by taking account of the desired operation durations Ai of each energy distribution device and, for the distribution device of order number 1, by searching for the optimal position(s) over the time interval of the operating sequence(s) of this distribution device which make it possible to minimize a function U representative of the fluctuations of the energy throughput over the time interval, the sequences of the other devices retaining the positions of the initial schedule, so as to obtain a resulting optimal schedule; and the above is repeated on the basis of the optimal schedule, using successively the distribution devices of higher order number up to the distribution device of order number N, and that which minimizes function U is adopted.
