Abstract

The aim of this study is to investigate the improvement of the performances and transient stability of grid connected Squirrel Cage Induction Generator based on Wind Farm (SCIG-WF) by using a new coordinated control between Grid Side Converter (GSC) of the Doubly Fed Induction Generator (DFIG) and photovoltaic solar plant converter (PV-SPC) as STATCOM. Thereby, the reactive power required by the SCIG-WF can be supplied either by the DFIGs (during normal condition) and with the PV-STATCOM during grid disturbances. This control strategy can fulfill the grid codes requirement such low voltage ride through capability by ensuring a no uninterrupted operation of the wind farm. The proposed control scheme is simulated by means of MATLAB/Simulink platform, based on a detailed system model. Through the simulated results, we can conclude that the proposed control for PV-SPC to operate as STATCOM is validated and the performances of the system are improved during normal and transient conditions.
