Abstract

The high level of penetration forces the wind turbines stay connected to the grid during the disturbances in order to enhance system stability. Requirements of grid codes for wind power integration will also be discussed regarding active power control, reactive power control and fault ride through (FRT) capability. For the MPPT, a proportional control loop is added to the torque control to reduce the influence of the inertia moment in the wind turbines, which can improve its dynamic performance. Furthermore, the grid side active power oscillation and dc-link voltage ripple can be suppressed by using the proposed controller. In this system, the entire control system by using proportional resonant controller to reduce the computational time. Simulation results showed the validity and efficiently of the proposed control approach in different conditions.

Keyphrases: Maximum Power Point Tracking (MPPT)., active power control, grid faults, low voltage ride through(LVRT), peak current limitation, voltage sag
