Electricity supply apparatus of an industrial site
First Claim
1. An electricity supply apparatus of an industrial site comprising a load configured to draw a predetermined current, said electricity supply apparatus comprising:
- a control device capable of being configured to calculate an amplitude of a control signal according to price information indicative of a price per time unit of a first current drawn from a mains and to generate said control signal;
an energy station capable of being configured to draw said first current from said mains to provide at least a first part of said first current to said load, to receive said control signal from said control device, and to reduce said first current by an amount proportional to said amplitude of said control signal; and
a battery electrically connected to said energy station and to said load, said battery capable of being configured to, when said first current drawn by said energy station from said mains is greater than said predetermined current which said load is configured to draw, recharge by drawing a second part of said first current from said energy station and, when said first current drawn by said energy station from said mains is smaller than said predetermined current which said load is configured to draw, to discharge by providing a second current to said load,wherein said control device is capable of being further configured to calculate said amplitude of said control signal also according to battery information relating to at least one of a recharge condition and a discharge condition of said battery, said amplitude having an intermediate value of a range delimited by a minimum value and a maximum value.

Abstract
An electricity supply apparatus includes a control device configured to calculate an amplitude of a control signal and to generate the control signal; an energy station configured to draw a current from a mains, to provide part of the drawn current to the load, to receive the control signal from the control device, and to vary the drawn current according to the amplitude; and a battery configured to recharge by drawing part of the drawn current and to discharge by supplying the load. The apparatus is characterized in that the control device is further configured to calculate the amplitude of the control signal also according to battery information relating to a recharge and/or a discharge condition of the battery.

15. A method for supplying an industrial site comprising a load configured to draw a predetermined current, by means of an energy station, comprising:
-
a) at said energy station, drawing a first current from a mains by means of said energy station and providing at least part of said first current to said load; b) at a control device, calculating an amplitude of a control signal according to price information indicative of a price per time unit of said first current and providing said control signal to said energy station; c) at said energy station, receiving said control signal and reducing said first current by an amount proportional to said amplitude of said control signal; and d) when said first current drawn by said energy station from said mains is greater than said predetermined current which said load is configured to draw, recharging a battery electrically connected to said energy station and to said load with a second part of said first current and, when said first current drawn by said energy station from said mains is smaller than said predetermined current which said load is configured to draw, discharging said battery by providing a second current to said load, wherein step b) comprises calculating said amplitude of said control signal also according to battery information relating to at least one of a recharge condition and a discharge condition of said battery, said amplitude having an intermediate value of a range delimited by a minimum value and a maximum value. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
