Abstract: A method for controlling a current injected to a power grid (2) from a renewable power plant (1), in response to a voltage event in the power grid (2), is disclosed. Occurrence of a voltage event in the power grid (2) is detected. At least a current at a point of common coupling (3) between the renewable power plant (1) and the power grid (2) is determined, and the determined current is provided to a power plant controller (4). The power plant controller (4) derives individual current setpoint corrections for at least some wind turbines (5) within the renewable power plant (1), based on the determined current, and dispatches each derived current setpoint correction to wind turbine controllers (6) of the corresponding wind turbines (5). The wind turbine controllers (6) control a current output of the respective wind turbines (5), based on measurements of current and/or voltage at a point of connection (8) between the wind turbine (5) and an internal grid (7) of the renewable power plant (1), and by taking the current setpoint correction dispatched from the power plant controller (4) into account.

Abstract: A method for controlling a wind turbine (2) is disclosed. During full load operation, a power reference value, P ref , representing a power level to be supplied to the power grid by the wind turbine (2), is received, and the wind turbine (2) is controlled in order to produce an output power which is at or near the power reference value, P ref , while maintaining a constant torque on the generator (6). In the case that the produced output power of the wind turbine (2) exceeds the power reference value, P ref , excess produced energy is stored in the energy storage system (10), and in the case that the produced output power of the wind turbine (2) is below the power reference value, P ref , stored energy is retrieved from the energy storage system (10). A power level being equal to the power reference value, P ref , is supplied to the power grid.
