Abstract: A method for optimizing the consumption, by loads, of an electrical power produced by at least one renewable source and at least one non-intermittent source connected to an electricity production and distribution network, the method including a step of determining a time profile of a renewable power produced by the at least one renewable source; a step of determining, among loads connected to the network, constraints on the use of said loads; a step of determining a plan of operation of said loads for maximizing the consumption of the renewable power produced by the at least one renewable source, while respecting said constraints on use, this determination including an evaluation of the consumption of the renewable power under the effect of a time-shift in starting said loads.
