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.
