Power Quality Investigation by Reduced Switching UPQC

European Journal of Electrical Engineering, 2020
In this paper, nine switches UPQC topology with different control techniques have been depicted and compared their performances to accomplish clear inspection of the best control techniques. As conventional UPQC having twelve switches of six legs enhances the switching losses, circuit complication, costly etc.

A coordination control between energy storage based DVR and wind turbine for continuous fault ride‐through

IET Renewable Power Generation, Volume 18, Issue 14, Page 2560-2574, 26 October 2024.
An innovative adaptive mode switching scheme has been introduced for DVR, primarily focused on minimizing the amplitude of injected voltage. A variable coordination coefficient that takes into account the margin of ESS regulation power and rotor inertia is introduced, which reduces ESS compensation capacity in DVR. Impedance‐based model considering the

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.
