Design of a chaos synchronisation‐based maximum power tracking controller for a wind‐energy‐conversion system

Abstract

This study proposes a maximum power tracking (MPT) controller based on chaos synchronisation (CS) for a windenergy-conversion system. The output power conversion of a wind generator depends on the wind speed, and therefore the optimal conversion of wind energy can be obtained by a variable-speed variable-frequency model. Based on a sensorless controller, CS can express dynamic behaviours by using an incremental conductance to adjust the terminal voltage to the maximum power point. A voltage detector based on the Sprott system is used to track the desired voltage and to control the duty cycle of a boost converter. For a permanent-magnet synchronous generator, the simulation results demonstrate the effectiveness of the proposed MPT controller.

A Novel Approach for Synchronizing of Fractional Order Uncertain Chaotic Systems in the Presence of Unknown Time-Variant Delay and Disturbance

“…Due to the nature of chaotic systems, they are widely used in various fields such as encryption, secure data transfer, etc. [20,21,35,25,12].…”

Overall power control strategy for small‐scale WECS incorporating flux weakening operation

“…While the MPPT problem has been studied in depth [9–12], a few works have been reported on development of an overall control strategy which is applicable to both Region I and Region II [6–8, 13–19].…”
