A Hybrid Control Algorithm for Extraction of Voltage Harmonics to Mitigate Power Quality Problems Using UPQC

摘要

The power angle concept based controller is incapable to enhance the MPQ of voltage in AC distribution network. Thus, a hybrid controller is proposed in this work to generate gate pulses of IGBT-based series converter. A hybrid control approach is used to enhance the multiple voltage-related issues. The performance of the hybrid control algorithm has been worked satisfactorily on MATLAB platform. The hybrid control algorithm can eliminate the voltage harmonics generated by source. These approaches can also be used in solar-based microgrid where source generates voltage harmonics. The IGBT-based shunt converter is used to enhance the multiple current qualities. Moreover, the performance of shunt control algorithm performs satisfactorily under various conditions of AC mains.
