Method for damping oscillations in a power grid

A method for damping oscillations in a power grid, the method comprising:

• defining a common reference time frame throughout the power grid,
• performing measurements, at at least one measurement position in the power grid, of voltage amplitude, voltage phase angle, frequency and/or power flow, and referencing the measurements to the common reference time frame,
• identifying an oscillation in the power grid and deriving a frequency, a phase angle and an amplitude of the oscillation, based on the performed measurements,
• selecting a damping entity being connected to the power grid at a damping position, the damping entity being capable of supplying and/or consuming active and/or reactive power to/from the power grid,
• generating a damping vector targeted at the damping position and referencing the common reference time frame, based on the identified oscillation in the power grid, the damping vector specifying a frequency, a phase angle and an amplitude, and providing the damping vector to the damping entity,
• the damping entity reconstructing an oscillation signal corresponding to the oscillation in the power grid, based on the damping vector and applying the common reference time frame, and
• the damping entity supplying and/or consuming active and/or reactive power to/from the power grid in accordance with the reconstructed oscillation signal, thus causing damping of the oscillation in the power grid.
