Abstract: A switching device including a switching unit having one or more electric poles and including, for each electric pole, a first power contact and a second power contact along which a line current can circulate and one or more solid-state switches; and a supporting frame adapted to be fixed to a supporting structure and including, for each electric pole, a third power contact and a fourth power contact along which said line current can circulate. The switching unit is reversibly movable, with respect to said supporting frame, between an insertion position and a withdrawn position. The switching unit includes, for each electric pole, at least a hydraulic circuit along which a cooling fluid can circulate to remove heat generated by said solid-state switches. The hydraulic circuit includes a first hydraulic connector and a second hydraulic connector that are coupled with or separated from a corresponding third hydraulic connector and a corresponding fourth hydraulic connector of said supporting frame, when said switching unit is in said insertion position or in said withdrawn position.

Abstract: A method is provided for controlling an electric power distribution grid, which includes one or more first grid devices having changeable set-points. The method includes the following steps: determining a consumption target value for the electric power distribution grid, the consumption target value being determined with reference to at an end instant of an observation time window, in which consumption of the electric power distribution grid at a given observation electric node of the electric power distribution grid is observed; and executing a control procedure for controlling the set-points of the first grid devices.

Abstract: Method for controlling an electric power distribution micro-grid, the micro-grid comprising: an electric coupling node that said micro-grid is electrically disconnectable from an electric power distribution main grid; one or more electric loads, each consuming a corresponding amount of electric power provided by the micro-grid, the electric loads including one or more disconnectable loads electrically disconnectable from the micro-grid; and at least an electric power source including one or more electric power generators. The method of controlling is carried out in response to the disconnection of the micro-grid from the main grid on a disconnection instant and comprises the following: determining whether the electric disconnection of the micro-grid from the main grid is due to a fault in the main grid; if it is determined that the disconnection of the micro-grid from the main grid is not due to a fault in the main grid, executing a load shedding procedure to disconnect in a selective manner one or more disconnectable loads; if it is determined that the disconnection of the micro-grid from the main grid is due to a fault in the main grid, determining whether a drop of a frequency of the micro-grid is in progress following the disconnection of the micro-grid; and if a drop of frequency is in progress following the disconnection of the micro-grid from the main grid, executing the load shedding procedure.
