    • A method and a device in an electric power network (1), comprising an active filter (4) controllable via a control input (41), for reducing disturbances generated by a disturbance source (6) located in and/or connected to the power network. A control member (8) is adapted, based on at least one first state variable (Y1i) sensed in the power network (1) and a model of the power network (1), to calculate the disturbances (X2) which occur in a second section (B--B) in the power network (1) without action from the active filter (4), to calculate a control signal (C1) such that, supplied to the control input (41), it would generate in the second section (B--B) the calculated disturbances (X2) with reversed polarity, and to generate the control signal (C1) and supply this to the control input (41). By sensing, in addition, at least one second state variable (Y2i) in the second section (B--B), the control signal (C1) can also be generated in dependence on the control deviation (DU) of the second state variable (Y2i) from a desired value (Y2R).
