Method for managing the load profile of a low or medium voltage electric network and a control system thereof

A method for managing the load profile of a low or medium voltage electric network, said electric network being supplied by at least an electric power source and comprising one or more electric loads (L10, L12, L23, L1, . . . , LK), which can be disconnected/connected from/with said electric power source, and one or more controllable switching devices (B10, B12, B23, B1, . . . , BK) for disconnecting/connecting said electric loads from/with said electric power source, which comprises the steps of:

• measuring a time window (WT) from a reference instant (tS);
• determine at least a check instant (tC) comprised in said time window (WT);
• executing a load profile control procedure (90) at said check instant, said control procedure comprising the steps of:
• acquiring first information (I1) related to the operating status of said electric network, said first information comprising a first data set (D1) comprising data indicative of a rank (R) assigned to each of said electric loads at said check instant (tC), a second data set (D2) comprising data indicative of a disconnection level (LD) assigned to said electrical network at said check instant (tC), a third data set (D3) comprising data indicative of a maximum and minimum level of absorbed energy (EMAX, EMIN) foreseen for said electric network at said check instant (tC);
• acquiring second information (I2) related to the electric energy consumption of said electric network, said second information comprising a fourth data set (D4) comprising data indicative of the energy (EA) that has been absorbed by said electric network up to said check instant (tC);
• updating said second data set (D2), if the energy absorbed by said electric network is not comprised within said maximum and minimum levels of energy,
• commanding the disconnection from said electric energy/power source of the electric loads, which are available for disconnection and are assigned with a rank (R) that is lower or equal than the disconnection level that is assigned to said electric network;
• commanding the connection with said electric energy/power source of the previously disconnected electric loads, which are available for connection and are assigned with a rank (R) that is higher than the disconnection level that is assigned to said electric network.
