Abstract: A wind power plant is provided. The wind power plant comprises at least one wind turbine and a power plant controller. The power plant controller is configured to detect whether a grid voltage exceeds a predefined threshold, and if it has detected that the grid voltage exceeds the predefined threshold, the power plant controller sends a reactive power reference to the at least one wind turbine, thereby causing the at least one wind turbine to reduce its reactive power output in response to the reactive power reference.
