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.

Mitigation of Voltage dip in WECS using UPQC [PDF]

International Journal of Trend in Scientific Research and Development, 2018
Currently, the quality of supplied power is important to several customers. Power quality is a service and many customers are ready to pay for it. In the future, distribution system operators could decide, or could be obliged by authorities, to supply their customers with different PQ levels and at different prices.
