Lithium-Ion Battery SOC Estimation Based on Adaptive Forgetting Factor Least Squares Online Identification and Unscented Kalman Filter

open access: yesMathematics, 2021
In order to improve the estimation accuracy of the battery state of charge (SOC) based on the equivalent circuit model, a lithium-ion battery SOC estimation method based on adaptive forgetting factor least squares and unscented Kalman filtering is ...

Ferromagnetically Shielded Fault Current Limiter (FS‐FCL) Evaluation in Power Line

open access: yesIET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study introduces a new ferromagnetically shielded FS‐FCL design and its control strategy for limiting and interrupting fault currents. The fully shielded core structure enhances inductance and prevents saturation, enabling an immediate fault response without causing voltage drop during normal conditions.

Power Talk in DC Micro Grids: Constellation Design and Error Probability Performance

open access: yes, 2015
Power talk is a novel concept for communication among units in a Micro Grid (MG), where information is sent by using power electronics as modems and the common bus of the MG as a communication medium.

Stability and Synchronization of MMC‐HVDC Systems Using SRF and Inertia‐Based PLLs

open access: yesIET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
This study investigates the influence of synchronous reference frame PLL (SRF‐PLL) and the inertia PLL (IPLL) on the stability of grid‐connected modular multilevel converter high voltage direct current (MMC‐HVDC) systems. The findings highlight intrinsic stability limitations of PLL‐based systems, offering insights toward more stable, PLL‐less ...

Total Distortion—A New Power Quality Index on Current Harmonic Evaluation for Users With Internal Loads and DERs

open access: yesIET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
ABSTRACT The IEEE Std 519–2022 IEEE Standard for harmonic control in electric power systems is widely used for controlling the harmonics in the electric power system. It uses the total demand distortion (TDD) for current harmonic evaluation at the point of common coupling (PCC).
