摘要：

Frequency stability is vital for the operation stability of power system. The total equivalent rotational inertia of power system decreases relatively upon large-scale penetration of wind power and threaten its frequency stability further. This paper analyzes the inertia support capacity of doubly fed induction generator and proposes a modified virtual inertia control strategy based on power-frequency response by improving the conventional control strategy. For each specific case, a corresponding control scheme is chosen. Besides, the rotor speed is protected by a control module associated with the secondary frequency regulation. Finally, an IEEE 14-bus system with doubly fed induction generator is established in DIgSILENT/PowerFactory simulation software, to verify the effectiveness of the proposed control method, which can respond to the frequency changes rapidly and effectively inhibit the frequency fluctuations caused by load changes and wind energy fluctuation.
