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.

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 ...
