摘要
A method of operating a wind power plant in a weak grid environment is provided to achieve desired system stability criteria and to support an electrical grid during disturbances or faults. The wind power plant is coupled to an electrical grid, and includes a power plant controller for controlling a plurality of wind turbine generators. The method includes, when a weak grid criterion is fulfilled, setting the power plant controller to operate in a weak grid mode by providing, when a grid voltage deviates beyond a threshold voltage, a reduced active power reference to the plurality of wind turbine generators. The method further includes, when the electrical grid recovers, generating a reduced amount of active power based on the reduced active power reference.
