Wind-speed estimation maximum power point tracking scheme for permanent magnet synchronous machine-based wind energy conversion systems

Abstract

Abstract This article assesses the real-time performance of a wind system based on a permanent magnet synchronous machine (PMSM). Despite the importance of modelling PMSM-based wind energy systems, the most significant and ongoing difficulty is still experimental research. This work suggests an effective and practical control system based on a wind-speed estimation (WSE) scheme to achieve the MPPT from PMSM in a variety of wind-speed scenarios. A PMSM simulation model with the proposed control system and a back-2-back (B2B) converter is constructed using the MATLAB/Simulink platform. The efficiency of the simulation model is confirmed through experimental validation tests by comparing the outcomes under identical wind-speed profiles and run-time conditions. The average value of the overall system efficiency during this period is 85.44%. In addition, the mean error of the wind turbine system is 1. 542. Based on these findings, it can be seen that the PMSM-based wind energy system performs satisfactorily, demonstrating the resilience of the designed control system. Moreover, remarkable tracking with elevated precision is attained for theoretical and experimental data. In addition, using the WSE improves the tracking ability, decreases the oscillation rate, and improves the system reaction.
