Abstract
GRID FREQUENCY RESPONSE Method and apparatus for determining inertia within a synchronous area of an electric 5 power grid are described. Power flow to and/or from a group of one or more power units is modulated on the basis of a sequence of control signals (figure 4a) and a frequency characteristic relating to a frequency of electricity flowing in the electric power grid measured (solid lines of figures 4b-4d). A frequency response characteristic associated with at least one area of the electric power grid is determined 10 on the basis of the measured frequency characteristic and the determined magnitude characteristic. From this it is determined whether the inertia in the area of the grid in which the power unit is located is low (figure 4b), medium (figure 4c) or high (figure 4d), and it enables frequency response characteristics within a synchronous area of the electric power grid to be easily determined. 15 [Figures 4a to 4d]
