Method for regulating the power consumed on an electric power grid and control entity of the consumption on this electric power grid
First Claim
1. A method for regulating power consumed on an electric grid, the electric grid being able to supply a plurality of consumers with electric current, preselected consumers being able to accept a predetermined decrease in power over a predetermined time range, the method comprising the following steps:
- transmitting to a first receiving unit of a control entity, regularly and by each preselected consumer, a message containing consumed power of said preselected consumer, a duration between two successive message transmissions for a given consumer being less than 1 hour,computing, by a computation member of the control entity, a maximum power reduction value for all of the preselected consumers and a maximum duration of that power reduction, said maximum power reduction value being computed based on the received consumed power of each preselected consumer,transmitting, by a transmission unit of the control entity, to a grid manager, the maximum power reduction value and the maximum duration for the computed power reductions, andsending, by the grid manager to a second receiving unit of the control entity, a command order for a commanded power reduction for a selected length of time, a value of the commanded power reduction being less than or equal to the computed maximum power reduction value and the selected length being less than or equal to the computed maximum duration of the power reduction.

Abstract
According to the inventive method, the power consumed on an electric grid (10), by preselected consumers (42, 44, 46, 48, 50, 52) being able to accept a predetermined decrease in power over a predetermined time range, is regulated. This method comprises the following successive steps: sending a control entity, regularly and by each preselected consumer (42, 44, 46, 48, 50, 52), a message (M1) containing the power consumed by said preselected consumer (42, 44, 46, 48, 50, 52); using the control entity (60) to compute a maximum power reduction value for all of the preselected consumers (42, 44, 46, 48, 50, 52) and a maximum duration of that power reduction; transmitting, using the control entity (60) and to a grid manager (62), computed values and maximum power durations; and sending, from the grid manager (62) to the control entity (60), a command order (79) commanding a power reduction for a selected duration.
