Inter-area oscillation damping techniques in wind power plants: A review

The deep penetration of wind energy in the modern power systems introduced many challenges due to the variability and limited predictability of wind. Wind power plants can provide ancillary services to the grid such as voltage support and reactive power compensation. The inter-area oscillation is one of the phenomena that adversely affect power transmission through weak tie-lines. Since the wind power plants are connected in remote grid areas, they can effectively contribute to damp these low-frequency oscillations. This paper investigates the techniques used in wind power plants to support grid stability by increasing the damping of the inter-area oscillations.
