Reactive power enhancement of dfig based on statcom for generation of wind energy

The rising significance of wind energy integration in power systems is attributed to its economic advantages.The utilization of Doubly Fed Induction Generators (DFIG) in wind energy is increasingly prevalent thanks to its inherent advantages.These include the ability to operate at variable speeds and autonomously control both active and reactive power, outperforming traditional generators.However, challenges arise when integrating such wind farms with the grid, manifesting as voltage stability issues and grid disturbances.These stem from DFIG's inadequate terminal voltage and frequency regulation, primarily due to insufficient excitation and resulting reactive power shortages.Therefore, enhancing terminal voltage and frequency generation is imperative.In this study, we aim to boost DFIG's performance by augmenting its reactive power through STATCOM, addressing supply voltage and frequency reductions caused by varying loads.Additionally, a neuro-fuzzy logic controller is employed to regulate generated voltage and frequency within the dynamic DFIG-STATCOM-load model, simulated using MATLAB/SIMULINK.
