Application of a three‐phase unified power quality conditioner in a microgrid

IET Smart Grid, Volume 7, Issue 6, Page 872-890, December 2024.
The UPQC system designed in this study used a series inverter to compensate the voltage balance sag–swell component, providing a stable voltage for the back‐end load. When the load was unbalanced, the feeder current was unbalanced. The shunt inverter compensated for the unbalanced current balanced the feeder current to improve power quality.

Power quality improvement of grid‐connected solar power plant systems using a novel fractional order proportional integral derivative controller technique

IET Renewable Power Generation, Volume 18, Issue 15, Page 3268-3284, 16 November 2024.
Integrate renewable energy system (RES) into grid‐connected load system in enhancing reliability and reducing losses. However, integrating these systems introduce power quality (PQ) issues, especially with non‐linear, critical, and imbalanced loads. Addressing this, a hybrid mantis search‐reptile search algorithm combined with a unified power quality ...

Improved model predictive control based on Luenberger state observer for LC‐coupling hybrid active power filter

Electronics Letters, Volume 60, Issue 13, July 2024.
An improved model predictive control with Luenberger state observer is proposed for LC‐coupling hybrid active power filter. This article utilizes the Luenberger observer to mitigate the steady‐state error without additional sensors, and the one‐sampling‐time delay compensation is given for the digital control delay.
