Variable-speed constant-frequency (VSCF) wind farms are gradually becoming a significant proportion of generation in weak grids with constantly increasing penetration rate, and it should certainly take responsibility of the grid frequency and voltage stability. Based on the P-Q performance curve of doubly fed induction generator (DFIG), by introducing static synchronous compensator (STATCOM), this paper presents a coordinated control strategy of active power and reactive power to deal with fault and load disturbance in weak grids. Simulation results show that the proposed coordinated control strategy can effectively improve the frequency and voltage stability of the grids.
