Energy transfer in nonlinear electrical networks - a modern perception of electrical power

Abstract

Networks for electric power distribution contain many nonlinear elements in conversion equipment, loads and power electronic converters. This leads to distorted currents and voltages in the network. Several contributions regarding a general power theory for nonlinear networks are evaluated for determining the different power components. A new theoretical proposal for determining these components, including the concept of scattered current is discussed. The appli­cation of this theory to the control of distortion compensators in power networks is discussed in principle.
