Fractional Order PI Controller Design for Control of Wind Energy Conversion System Using Bat Algorithm
This study presents intelligent control of the global wind energy conversion system (WECS), through a Permanent Magnet Synchronous Generator based variable speed Wind Turbine (PMSG-WT). The proposed control design is touched many parts in PMSG-WT, which are control of Maximum Power Point Tracking, Pitch Angle controller, and control of PMSG. The proposed controller is designed using Fractional PI controller. Where the controller parameters are successfully tuned by a new metaheuristic optimization Bat algorithm (BA). To highlight and compare the performances of this controller, it is employed under changes wind speed condition and compared with the conventional PI controller. Simulations results show clearly effectiveness of the proposed controller. Moreover, the PMSG-WT plant is effectively controlled at different operating conditions by the proposed scheme.
