Maximum Power Tracking Control for a Wind Turbine System Including a Matrix Converter

The state of the art of wind energy conversion systems and technologies: A review

“…The sliding mode power feedback MPPT method was proposed in [43], which can reduce the negative effects of both the uncertainty regarding k opt and the change in optimal operating point due to wind speed turbulence. In [44], a mechanical speed-sensorless power feedback control with a matrix converter (MC) was proposed without requiring a shaft speed sensor. A novel MPPT control with an adaptive compensation control was proposed in [45] based on the optimum torque feedback control.…”

Neural Network Based Maximum Power Point Tracking Control with Quadratic Boost Converter for PMSG—Wind Energy Conversion System

“…The power characteristic specifies that there is a specific optimum turbine speed for each wind speed where the maximum power is captured. To operate the WECS at that specific point various maximum power point tracking (MPPT) algorithms have been proposed in the literature [5][6][7][8][9][10]. The foremost controllers that are widely used are power signal feedback (PSF), hill climb search (HCS) or perturb and observe (P&O), tip speed ratio (TSR), optimal However, the WECS being a high voltage application increases the switching voltage and stress across the switch, thus reducing the efficiency and risking the failure of switching conversion process [21].…”

A novel MPPT method for enhancing energy conversion efficiency taking power smoothing into account

“…Several MPPT methods are introduced in [7], such as tip-speed ratio (TSR) [8,9], perturbation and observation (P&O) method [10][11][12], optimum torque control (OTC) [13][14][15] and power speed feedback (PSF) [16,17]. The conversion efficiency of TSR is higher than other conventional methods [15].…”

“…But accurate wind speed information is needed [7]. The advantage of P&O is its independence and simplicity since the wind turbine characteristic curve is not necessary [16]. However, the control performance is sensitive to P&O step-size, significantly [10].…”
