Doubly-fed induction generator (DFIG) is current mainstream wind power generator adopt active and reactive power decoupling control. The active power of DFIG is not affected by the system frequency, and could not participate in the system frequency regulation. The frequency regulation problem caused by wind power penetration increase is becoming more and more serious, and wind power integration standard presents a new requirement for wind farm participation in system frequency regulation. In order to make the wind power generator behave as the conventional one, this paper proposes a new wind power generator based on energy storage system, and using virtual synchronous generator control strategy to study the frequency modulation of wind farm. The simulation results show the wind farm based on energy storage system can effectively support the system frequency and performances the characteristics of conventional generator, thus improving dynamic frequency characteristics of power system containing wind power.
