Abstract: This work is motivated by the issue, 'If a 6-phase doubly fed induction generator (6-phase DFIG) based wind energy generation system (WEGS) will supply power to society in the future, then what type of MPPT system will be appropriate for a 6-phase DFIG-based wind energy generation system?'. The maximum power point tracking (MPPT) technique has been adopted to obtain maximum power under various operating situations using a machine-side converter (MSC) linked to a traditional doubly fed induction generator (DFIG) and solar photovoltaic cells throughout the last several decades. Due to several two-dimensional space harmonics, the MPPT technique to the MSC of 6-phase DFIG cannot be applied directly, and as a result 6-phase DFIG modelling is first introduced in a distinct two-dimensional plane. An appropriate MPPT algorithm has been developed based on the proposed modelling that provides the synergy between the 6-phase DFIG and MPPT system. In addition, the modelling of a WEGS is also covered in this study, along with the modelling of a 6-phase transformer, a DC link capacitance, and a wind turbine. Furthermore, real-time hardware-in-loop experimentation has been conducted to validate the efficacy of the proposed model.

Keywords: 6-phase DFIG-MPPT synergy; 6-phase DFIG; machine-side converter; maximum power point tracking.
