The ongoing increasing application of the large-scale new energy makes it difficult to maintain the stable control using the traditional control methods for the grid. As an available solution to the current challenge, the proposed control strategy of virtual inertia achieving frequency response for doubly fed induction generator systems is introduced. The specific structure and procedures of DFIG control are also given. The effects of crucial parameters based on the dynamic and static performances of system and stability analysis are addressed. The theoretical analysis, simulation and experiment results indicate the efficiency and validity of the designed strategy.
