Currents’ Physical Components (CPC) concept: A fundamental of power theory

The paper introduces readers to currently the most advanced power theory of electrical systems with non-sinusoidal voltages and currents, along with fundamentals of their compensation, based on the concept of currentspsila physical components (CPC). It includes single-phase systems and unbalanced three-phase systems with linear, time-invariant (LTI) and harmonic generating loads (HGLs).
