A complicated test system with integration of doubly‐fed induction generator (DFIG)‐based and permanent magnet synchronous generator (PMSG)‐based wind farms is built up in this study to explore and exploit the interactions between DFIG unit and PMSG unit on the issue of sub‐synchronous oscillation (SSO). With detailed modelling of wind farm units, transmission lines and loads, the SSO modes are elaborately analysed through eigenvalue analysis and participation factor methods. The level and position of series compensated lines are discussed leading to some useful comments and suggestions. Besides, the power outputs of the two wind farm types are compared to investigate their potential influences on the oscillation, and the most influential proportional–integral parameters producing the potential risks of oscillation are chosen out.
