Method and a device for balancing electric consumption
First Claim
1. A method for balancing electric consumption generated by a plurality of electric loads, the method comprising:
- estimating an absorbed energy (Ek) by the loads in a predetermined time interval, and if a value of the estimation of absorbed energy (Ek) by the loads is not within an interval defined by a minimum (THRk,min) and a maximum (THRk,max) consumption threshold,calculating a quantity of energy to be varied in accordance with a difference (Δ
h) between the value of the estimation of the absorbed energy (Ek) and an expected value of energy (THRk,exp),determining a strategy comprising at least an action (Vri) to be carried out to vary the energy supplied to the single loads, in order to reduce the difference (Δ
h) between the estimated absorbed energy (Ek) and the expected value (THRk,exp) thereof,actuating a scheduling of electric consumption in accordance with a determined strategy; and
verifying the effects of a scheduling of electric consumption and,determining a new energy variation strategy, if the verification has a negative outcome, wherein the verification step of the effects of a scheduling of electric consumption comprises calculating a difference between the effects of the scheduling in action and a theoretical forecast of the effects, where the verification has a negative outcome if the difference is greater than a margin of tolerance.

Abstract
A method for balancing electric consumption generated by a plurality of electric loads includes: estimating an absorbed energy (Ek) by the loads in a predetermined time interval, and if a value of the estimation of absorbed energy by the loads is not within an interval defined by a minimum and a maximum consumption threshold, calculating a quantity of energy to be varied in accordance with a difference between the value of the estimation of the absorbed energy and an expected value of energy, determining a strategy including at least an action to be carried out to vary the energy supplied to the single loads, with an aim of reducing the difference between the estimated absorbed energy and the expected value thereof, actuating a scheduling of electric consumption in accordance with a determined strategy.
