Performance Assessment of Perturbation and Observation Algorithm for Wind Turbine

Maximum power point tracking algorithms for wind power generation system: Review, comparison and analysis

“…In the control method, if $${P}_{t{opt}}$$ is used to replace the electromagnetic torque as the index of feedback, this method is called power signal feedback (PSF) control 56 . Its operating principle is essentially the same as that of OT control 44,55,57,58 except that the feedback and reference are active power instead of torque. Although the PSF control strategy can react quickly to changes in wind speed and is straightforward and easy to implement, the accuracy of the control is greatly influenced by the maximum power curve.…”

Nonlinear Maximum Power Point Tracking Control Method for Wind Turbines Considering Dynamics

“…where U s is the stator voltage. Substituting Equation (2) into Equation (4) produces the relationships between the equivalent rotor currents and the equivalent stator currents:…”

“…The strategies to maintain C p or power close to its maximum value (TSR to optimal TSR) is known as maximum power point tracking (MPPT). There are four main categories of the MPPT methods: power signal feedback (PSF) control, perturbation and observation (P&O) control, tip-speed ratio (TSR) control, and optimal torque (OT) control [1][2][3]. PSF control and OT control are similar in performance and commonly used in large-scale wind turbines [4].…”
