COMPARATIVE POWER QUALITY ASSESSMENT OF WIND AND SOLAR ENERGY SYSTEMS WITH INNOVATIVE POWER CONDITIONING DEVICES

Abstract

This study presents a comparative power quality assessment of wind and solar energy systems, focusing on the role of innovative power conditioning devices in enhancing system performance. Power quality issues such as voltage fluctuations, harmonics, and power factor variations are common in renewable energy systems due to their intermittent nature. Innovative power conditioning devices, such as advanced inverters, dynamic voltage restorers, and hybrid systems, are evaluated for their effectiveness in mitigating these issues. Through simulation and experimental analysis, the study assesses key power quality metrics, including Total Harmonic Distortion (THD), voltage stability, and frequency variation, in both wind and solar energy systems. The results demonstrate the significance of power conditioning devices in improving the stability and reliability of power output, with wind energy systems showing a higher sensitivity to voltage fluctuations and solar systems being more prone to harmonic distortions. The findings suggest that the integration of advanced power conditioning technologies can substantially enhance the quality of power from renewable sources, making them more viable for grid integration and large-scale applications.
