METHOD FOR DETECTING POWER OSCILLATION IN AN ELECTRIC POWER GRID

A method for detecting power oscillation in an electric power grid, wherein the method comprises: integrating a filtered signal on a first interval, the filtered signal being associated with the electric power grid; based on the integration of the filtered signal on the first interval, determining a positive half-period area of the filtered signal and a negative half-period area of the filtered signal, one of the positive half-period area and negative half-period area being immediately subsequent to the other one; and determining that a power oscillation in the electric power grid is detected if the following two conditions are met:
