Improved Fuzzy Logic MPPT Controller of Stand alone WECS-based PMSG under Stochastic Wind Environment

This paper discusses the modeling and control of a Standalone WECS-based PMSG, the aim is to achieve an optimal operation of the studied WECS under a typically stochastic wind environment. The Maximum Power Point Tracking (MPPT) is guaranteed through the tracking of an optimal generator speed using an Improved Fuzzy Logic Controller based on intelligent algorithms. The effectiveness and the benefits of the proposed approach are demonstrated by numerical simulation using Matlab/SIMULINK. The obtained results indeed confirm a good tracking performance of the proposed controller.
