COMPUTER-IMPLEMENTED METHOD OR ASSESSMENT OF A POWER DISTRIBUTION GRID

A computer-implemented method for assessing the state of a low-voltage distribution network comprising a plurality of nodes (17), the method comprising: selecting a node (23) of the low-voltage distribution network (300); assigning a neural network (60) to the selected node (23); training (44) the neural network with a collection of historical data (41) collected during a certain time period, the historical data (41) comprising discrete values of active power measured at each phase (R, S, T) of the selected node (23), discrete values of reactive power measured at each phase (R, S, T) of the selected node (23), magnitude of voltage at each phase (R, S, T) of the selected node (23) and angle of voltage at each phase (R, S, T) of the selected node (23); providing the trained neural network (54) with actual values of active power measured at each phase (R, S, T) of the selected node (23) and reactive power measured at each phase (R, S, T) of the selected node (23); calculating (56) by the trained neural network (54) the magnitude of voltage at each phase (R, S, T) and the angle of voltage at each phase (R, S, T) of the selected node (23).
