Abstract
The rotor speed and system frequency are decoupled in the MPPT control mode of D-PMSG wind turbine, which can not provide additional active power to participate in frequency control and lead to insufficient frequency regulation ability. Aiming at improving the frequency response characteristic of D-PMSG wind turbine and solving the problem of mutual interference between additional inertia control and MPPT control, an improved additional inertia control strategy is proposed. The control method can employ the auxiliary power of additional inertia control to support system frequency and compensate the active reference of MPPT control through speed regulation according to the system frequency variations. Simulation results indicate better inertia response characteristics and great improvement of mutual interference.
