Time domain harmonic state estimation in unbalanced power networks based on optimal number of meters and the principle of half‐wave symmetry

IET Generation, Transmission & Distribution, 2017
This study proposes a time domain methodology for harmonic state estimation (HSE) in power systems. The proposed methodology is formulated to analyse the unbalanced operation of three‐phase power systems including non‐linear loads.

A learning‐based hierarchical energy management control strategy for hybrid electric vehicles

IET Control Theory &Applications, Volume 18, Issue 18, Page 2725-2741, December 2024.
A hierarchical learning EMS is developed for hybrid electric vehicles (HEVs) in car‐following scenarios. A tube‐based iterative learning model predictive control scheme is proposed for speed tracking under uncertainties. The operation repetition is helpful to improve fuel efficiency of HEVs.
