AI‐Driven Optimization Techniques for Power Quality Improvement in Microgrids: Trends, Techniques, and Future Directions

Energy Science &Engineering, Volume 14, Issue 1, Page 583-610, January 2026.
Decentralized energy systems are gaining momentum, and microgrids have become a vital component of the modern power landscape. Yet, maintaining power quality within these systems presents ongoing challenges due to the presence of nonlinear loads, variable renewable energy sources, and frequent switching operations.

Multi‐Input Backstepping Control for Transient Stability Enhancement in Power Systems With PMSG‐Based Wind Turbines and UPFC

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
In the paper, first, the modelling of a power system with a Permanent Magnet Synchronous Generator (PMSG), Unified Power Flow Controller (UPFC) and Doubly‐Fed Induction Generator (DFIG) is fully considered. Next, the possible candidate control law and its implementation technique on the power network are examined.

Metaheuristic‐Based Load Frequency Control of Multi‐Source Renewable Systems With SMES and AC‐DC Parallel Tie‐Lines

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study proposes a hybrid evolutionary exploration algorithm (HEEA) that integrates genetic algorithm and grey wolf optimiser to co‐tune PID controller gains and SMES parameters in a two‐area AC‐DC interconnected renewable system. The proposed method achieves faster convergence, lower ITAE and improved stability compared to existing metaheuristics ...

Overvoltage Suppression Strategy for HPFC Based on Bandwidth Adaptive LADRC and Improved Reactive Power Control

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
Overvoltage occurs in Hybrid Power Flow Controllers (HPFC) under specific fault conditions. This paper proposes a linear Active Disturbance Rejection (LADRC) strategy integrating reactive power adaptive regulation and bandwidth parameter adaptive adjustment to suppress whole‐process overvoltage in HPFC.
