A Physics‐Informed Neural Network‐Based Transient Overvoltage Magnitude Prediction Method for Renewable Energy Stations Under DC Blocking Scenarios

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
This paper first derives an analytical expression for the transient overvoltage (TOV) magnitude at critical nodes in the system caused by DC blocking (DCB) faults. Subsequently, an analytical formula is developed to characterize the relationship between the multiple renewable energy stations short circuit ratio (MRSCR) and the transient voltage rise ...

Modal Analysis of Power System With High IBR Penetration Based on Impedance Models

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
A unified physical interpretation of modal analysis based on the impedance model (MAI), based on the electrical distance perspective is further presented.To make MAI more applicable and accurate, a new total evaluation index is proposed to fix the potential misjudgment when computing the admittance sensitivity factor.

Real‐Time Tracking of Fault Development and Faulty Feeder Identification Method for Resonant Grounding System Based on Transient Information During Arc Suppression

IET Generation, Transmission &Distribution, Volume 19, Issue 1, January/December 2025.
This paper proposes a fault tracking and feeder identification method based on the arc suppression process of resonant grounding systems. By analyzing the transient characteristics of zero‐sequence signals after full compensation by the arc suppression coil, the method enables both sensitive transition resistance identification (reflecting fault ...

Artificial Intelligence Approaches for SOH Estimation in Lithium‐Ion Batteries: A Comprehensive Review of Progress, Critical Evaluations, Challenges, and Toward Future Outlooks

Applied Computational Intelligence and Soft Computing, Volume 2025, Issue 1, 2025.
In recent years, safety issues with electric vehicles (EVs) have grown. These EVs are powered by rechargeable lithium‐ion batteries (LIBs), which are key energy storage systems. The accurate estimation of these LIBs state of health (SOH) is crucial for reliable performance and reduction in safety issues.

Dual‐port network‐based impedance modelling and AC‐port characteristic analysis of wound rotor synchronous machine for more electric aircraft

IET Electric Power Applications, Volume 18, Issue 12, Page 1807-1817, December 2024.
This paper introduces a novel method to model the WRSM in a modular and cascaded manner. By connecting the dual port of each component from the rear stage to the front stage in a cascaded way, a dual‐port network can be built to describe the external impedance characteristics of the WRSM.

Analysis of voltage limit‐induced barrier for connecting inverter‐based distributed generators to medium voltage networks: Australian case studies

IET Energy Systems Integration, Volume 6, Issue 4, Page 565-580, December 2024.
Abstract Inverter‐based distributed generators (IBDGs), mainly solar photovoltaic, connected in medium‐voltage (MV) networks cause challenges, such as voltage limit violations, for distribution network service providers (DNSPs), and require advanced network management strategies to mitigate these challenges.
