摘要

Grid-connected Doubly Fed Induction Generator (DFIG)-based wind energy systems face persistent challenges in maintaining voltage stability, mitigating harmonics, and ensuring reliable power quality under fluctuating wind and fault conditions. This research proposes a Coordinated Dynamic Compensation Control Strategy (CDCCS) for grid-connected DFIG-based wind energy systems, addressing voltage stability, harmonics, and power quality issues. By integrating a Static Synchronous Series Compensator (SSSC) and STATCOM, optimized using Harmony Search–Ant Colony Optimization (HS-ACO), the strategy enhances system stability during disturbances and improves steady-state performance. The model significantly reduces harmonic distortions under fault conditions to 2.72% (grid current), 2.30% (grid voltage), 5.19% (load current), and 5.53% (load voltage), compared to higher values in conventional systems. The proposed approach ensures reliable renewable energy integration and improved fault ride-through capability.
