Abstract
A method for determining the contribution of a grid subsystem () to oscillations in grid frequency experienced by an external electrical grid () in an electrical power network (). A measurement of grid frequency is taken in the grid sub-system () and/or the external electrical grid (). The measurement(s) of grid frequency can be used to extract oscillations in grid frequency in the grid subsystem () and/or the external electrical grid (). A measurement of active power is recorded on a transmission line () between the grid subsystem () and the external electrical grid (). The phase relationship between the oscillations in grid frequency and the oscillations in active power allows the contribution of the grid subsystem () to oscillations in grid frequency in the external electrical grid () to be determined.
