Using Dual Type 2 Fuzzy Logic Technique to Increase Performance of the Wind Turbine System

This paper outlines a maximum power point tracking (MPPT) method based on the tip speed ratio (TSR) of a singular wind power system, operated by a doubly-fed induction generator (DFIG). The conventional MPPT approach using a proportional-integral (PI) regulator faces multiple challenges, including those related to maintaining the system’s stability and performance during steady state. To realize a more efficient variable-speed wind turbine system, MPPT strategies rooted in artificial intelligence, namely type 1 fuzzy logic control (T1-FLC) and type 2 fuzzy logic control (T2-FLC). The designed MPPT techniques effectiveness is validated using numerical simulations executed via MATLAB. The derived results demonstrate the efficacy of our proposed MPPT strategies, with a notable preference for T2-FLC over T1-FLC and the traditional PI control.
