Modeling and Coordinated Control Design for Brushless Doubly-Fed Induction Generator-Based Wind Turbine to Withstand Grid Voltage Unbalance

Abstract

Grid codes require wind turbines to have capability to withstand a certain grid voltage unbalance without tripping. However, existing controls for brushless doubly-fed induction generator (BDFIG) based wind turbine under grid unbalance have many problems such as difficulty in realizing decoupling control, involvement with flux or current estimations, and complex control structure. Moreover, the existing studies only focused on the control of machine side converter (MSC), but the coordinated This work is licensed under a Creative Commons Attribution-NonCommercial-NoDerivatives 4.

Suspension Strategy of Maglev Vertical Axis Wind Turbine Based on Sliding Mode Adaptive Neural Network Predictive Control

“…T HE wind power generation in low wind speed areas is increasingly on the agenda with the development of energy strategies, and low wind speed wind power is gradually attracting attention [1][2][3]. But unfortunately, low wind speed areas often have the disadvantage of frequent changes in wind speed and wind direction, so the application of vertical axis wind turbines (VAWT) has received extensive attention.…”
