Adaptive Control-Based N-STATCOM for Harmonic Mitigation and Voltage Regulation in Grid-Connected Wind Energy Systems

Integrating wind energy systems into grid-connected networks poses power quality (PQ) challenges, such as voltage fluctuations, harmonic distortions, and reactive power issues, affecting system stability and efficiency. This paper proposes a Novel Static Synchronous Compensator (N-STATCOM) to enhance PQ through dynamic reactive power compensation, mitigating voltage sags, swells, flickers, and harmonics while optimizing the power factor. Using MATLAB/Simulink, the system's performance is evaluated under varying wind speeds and load conditions. Results show that N-STATCOM improves voltage stability, reduces total harmonic distortion (THD), and enhances reactive power compensation compared to traditional STATCOMs. Its control strategy ensures rapid response to grid disturbances, maintaining consistent PQ. This study demonstrates N-STATCOM's effectiveness in addressing PQ issues, offering insights for integrating renewable energy while ensuring grid reliability and efficiency.
