Study of the Overvoltage and Its Distribution Characteristics in an Oil‐Immersed Iron‐Core Reactor Disconnected by an SF6 Circuit Breaker

IET Electric Power Applications, Volume 20, Issue 1, January/December 2026.
This paper primarily investigates the patterns of overvoltage changes during an interruption of oil‐immersed iron‐core reactors by circuit breakers and their distribution along the axial windings of the reactor, which optimises the winding structure. ABSTRACT This paper primarily investigates the patterns of overvoltage changes during an interruption ...

Analytical Frameworks and Theories of Electric Power in Non‐Linear Circuits

IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.
Based on the challenges of distorted currents and non‐linear components in modern power grids, this article reviews seminal electrical power theories that seek to generalize the traditional definitions of active, reactive, and apparent power. It provides a detailed analysis of their mathematical foundations, practical implementation, and validity.

Co‐Simulation Microgrid With Distributed Control Based on a Multi‐Agent System and Communication With Adaptive Update Rate

IET Smart Grid, Volume 9, Issue 1, January/December 2026.
This study proposes a distributed control system using a multiagent system (MAS) to regulate the DC bus voltage in a grid‐connected microgrid through a co‐simulation environment. The framework integrates MAS (Python), TCP/IP communication and standard simulation tools (PLECS, PSIM and RTDS), enabling coordinated operation of PV arrays, battery storage ...

An Efficient Hybrid Islanding Detection Method for Microgrids Using Kalman Filter

Engineering Reports, Volume 7, Issue 12, December 2025.
Islanding condition gives rise to several problems in distributed generation networks, including power quality disturbances, equipment damage, interference with grid protection, and danger to the utility crews. To avoid islanding detection failure of the passive section in case of a close matching between islanded generation units and loads, the active

Lightning‐Induced Overvoltage on Overhead Distribution Line via Hybrid MTL‐PEEC Method

High Voltage, Volume 10, Issue 6, Page 1464-1473, December 2025.
ABSTRACT Transient simulation are more economical and adaptable means of studying lightning overvoltage for overhead distribution line system compared to experiments. A hybrid multi‐transmission‐line (MTL)‐partial element equivalent circuit (PEEC) method proposed for lightning‐induced electromagnetic pulse (LEMP) simulation is verified using the rocket‐

Development of an Electromagnetic‐Thermal Circuit Model for Single‐Phase Three‐Limb Transformers

High Voltage, Volume 10, Issue 6, Page 1545-1557, December 2025.
ABSTRACT Analysing the heat states of transformers under DC bias requires careful consideration of their own structural and material characteristics. Although the 3D finite element method (FEM) is a reliable way of simulating all the details of transformers, it may be time‐consuming or have encountered convergence difficulties due to the complex ...
