V. CONCLUSIONS

• Power systems require taking into account the reactive power of the wind farm in order to contribute to the network stability, thus operating the wind farm as active compensator devices. The impact of SCIG wind farm connecting into a distribution network is completely studied in this paper.

• when STATCOM is installed at wind farm, with STATCOM technology to have the capability to increase stability and improve system dynamic response following disturbances. Application of STATCOMs for wind farm is to increase power quality, regulate reactive power at the grid POC and reduce voltage flicker.

V. CONCLUSIONS

Application of STATCOMs for wind farm use DFIG turbines and for large-scale wind farm connect into the grid to increase power quality, wind power systems stability, reduce reactive power, reduce voltage flicker and suitably manage the available capacity on the sources of reactive power.W
