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

open access: yesIET 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.
