Regarding the issue of doubly fed wind turbines being unable to provide support for grid frequency.Firstly,study the operating principle of doubly fed wind turbines.Then,analyze the additional pitch angle control strategy and integrated virtual inertia control strategy to achieve the frequency support capability of doubly fed wind turbines.Finally,the simulation verifies the effectiveness of the frequency support capability control strategy for doubly fed wind turbines.
