Abstract

Abstract:
Supercapacitors are neutral systems that contain an electric double layer at the interface
of the metal electrode and electrolyte dielectric material. The neutrality of the system is
obtained by a diffuse layer of positive charges in the electrolyte opposing a centralized
layer of negative charges in the electrode. Thus, the double layer is formed in which the
separation of each layer is on the order of a few angstroms. As a first trial, in this paper
the technology of supercapacitors is applied theoretically for the electrical power
distribution systems. A simple distribution system (two-node system) is proposed. The
system represents the one line diagram of a source – line - load system. By increasing
the capacitance of the supercapacitor at the load bus, the load flow analysis results
showed that the over voltage problem and also the high losses problem at load are
removed.
