Abstract: The aim of this paper is to present a new coordination control between active crowbar and PV-STATCOM to enhance the performance and the reliability of grid connected double-fed induction generator (DFIG)-based wind farm under grid disturbance. A new technique to detect the fault is also presented. It is based on monitoring the rotor voltages and currents of the DFIG by using the symmetrical components approach. A modified control scheme of the solar farm converter is adopted to operate as STATCOM in the presence of a disturbance. The proposed control scheme is simulated under MATLAB/Simulink platform to verify its efficiency.

Keywords: double-fed induction generator; DFIG; wind power plants; WPPs; voltage dip; crowbar protection; low voltage ride through; LVRT; static synchronous compensator; STATCOM; photovoltaic system; system stability.
