Wind turbine control for a weak grid reducing the production of active power

摘要

It is described a method for controlling a wind turbine (101) connected to a node (127) connected to a utility grid (129), wherein to the node a plurality of other wind turbines (102) is connected, the method comprising: measuring a quantity (134, 135, 136) indicative of a slope (403) of a voltage (V) at the node (127) in dependence of active power (P) delivered to the node; determining that the slope (403) is smaller than a negative slope limit (414); performing a measure, in order to increase the slope (403) above the slope limit (414).
