Adaptive Control of a PV‐Integrated Unified Power Quality Conditioner for Remote Low‐Voltage Distribution Networks

IET Renewable Power Generation, Volume 20, Issue 1, January/December 2026.
An adaptive VLLMS‐based control strategy is developed for a PV‐powered UPQC, enabling simultaneous PQ mitigation and distributed power management. Filterless extraction and decoupling of non‐ideal voltage and current components provide fast convergence, improved dynamic response and stable DC‐link voltage under PV power fluctuations.
