“…It is necessary to apply a new, powerful, and suitable tuning algorithm to select the proposed MPPT controller gains in an optimal manner. 35 After the inclusive literature review and simulations, TLBO has been decided to apply for the optimal controller parameters selection. 38 TLBO is a recent and self-regulating algorithm that is independent of algorithmspecific tuning constraints and hence, becomes a standard tuning algorithm for WECS.…”

“…where k(e) is a nonlinear error function formulated as given in Equation (23 To get an approximate model of FOPID controller and realization in terms of integer order Laplace function using appropriate techniques like "Oustaloup approximation" 35 due to the multiple transformations that is, continuous to the discrete-time domain, leads to an unavoidable mismatch between the continuous and discrete transfer function responses of the overall system, causing the loss of "long memory feature" of the integral term in the FOPID control output. 37 The control action of the proposed controller is derived from a long memory discrete PID (LDPID) controller, which according to 37 , not only provides similar high performance as that of FOPID but also eliminates the aforementioned limitations.…”

“…TLBO is used to find the optimal value of a defined fitness function by allowing variation in system variables within permissible bounds. TLBO can be explained as in 35 TLBO updates its new solutions based on the difference between the previous and newly attained values which are analogous to grades attained by learners.

Objective To maintain the operation of a wind turbine at its maximum efficiency and for the extraction of maximum power from the wind. Method In this paper, at first, a novel application of fractional‐order nonlinear proportional‐integral‐derivative (FONPID) controller is proposed in the machine side converter (MSC) control loop of a 2 MW grid‐connected wind energy system. Then, the grid side converter (GSC) is controlled to ensure the unity power factor of the understudy system. To extract the maximum power from the wind, the application of the proposed controller is applied to a well‐established TSR MPPT control method, which compares optimal and actual values of rotor speed, and generated error is given to the proposed controller to vary the rotor speed accordingly. Moreover, improved MPPT performance offered by the proposed FONPID controller has also been compared to well‐established existing controllers based TSR MPPT methods. Furthermore, parameters of the proposed and existing controllers in the TSR MPPT control loop are also tuned using teaching‐learning based optimization (TLBO) and obtained performance is compared with the performance of particle swarm optimization (PSO) to show effectiveness. Results The generator speed offered by the proposed FONPID based TSR MPPT method effectively tracks its reference values far better than the extant controller based TSR MPPT method, whereas extant NPID has less overshoot as compared to the extant PID based TSR MPPT method. Conclusion To perform the effective operation of achieving MPP, q‐axis current of the stator has been controlled by the proposed FONPID based TSR MPPT method in such a style that rotor speed can be operated at its optimal value where the generator has the maximum power for given wind speed. DC‐link voltage is controlled at its rated value to guarantee the unity power factor operation using the GSC controller. FONPID based TSR MPPT method provides a better and robust MPPT operation than the PID, NPID, and FOPID controllers based TSR MPPT method. The performance has been assessed in terms of minimized fitness function value, steady‐state error, settling time, and percentage overshoot.

The mechanical power of the wind turbine has a cubic relationship with wind speed. Therefore, during high wind speed, the output power of wind turbine driven permanent magnet synchronous generator (PMSG) needs to be maintained at rated value effectively. This can be achieved by the pitch angle control of the wind turbine. In this paper, a new application of the fractionalorder nonlinear proportional-integral-derivative (FONPID) controller is pro
