1. A method for monitoring an electric power grid, the method comprising:
detecting one or more physical stimuli generated endogenously in the electric power grid, the physical stimuli belonging to nominal or near-nominal operation of the electric power grid and generating at least one of voltage fluctuation and current fluctuation that exceeds at least one threshold;
obtaining, while the one or more physical stimuli is effective, a first set of measurement data associated with a first location of the electric power grid;
computing a grid strength of the first location of the electric power grid on the basis of the first set of measurement data; and
mapping the grid strength to a grid strength of a second location of the electric power grid on the basis of the first set of measurement data and correlation between electrical characteristics of the first location and the second location when measurement data from the second location is at least currently unavailable.
