GRIDSTABLE: OPTIMIZING POWER QUALITY IN VARIABLESPEED WIND ENERGY CONVERSION SYSTEMS

Abstract

Variable-speed wind energy conversion systems (VSWECS) have become a prominent solution for renewable energy generation, offering improved efficiency and adaptability to fluctuating wind conditions. However, the integration of these systems into the electrical grid can introduce power quality issues such as voltage fluctuations, harmonics, and reactive power imbalances, which may affect grid stability and reliability. This study, GridStable, proposes advanced control and compensation techniques for enhancing power quality in gridconnected VS-WECS. By employing dynamic voltage support strategies, active power filters, and adaptive control algorithms, the framework mitigates harmonics, stabilizes voltage, and ensures reactive power balance. Simulation and experimental results demonstrate that the proposed approach effectively improves grid stability, enhances power quality, and enables reliable integration of variable-speed wind turbines into modern electrical networks.
