Journal on Power Systems Engineering 2322–0376 1 3 15 20 Element Incidence Matrix, Radial Distribution Power Flow, Linear Recursive Equations, Transmission Loss, Differential Evolution Distribution system plays an important role in supplying the electricity from generation to the consumers via transmission system. The power system is one of the most complex systems in the world. Because of the high R/X value the losses in the distribution system is more. The one of the roles of capacitor is reducing the losses in the distribution system. This paper presents an improved method for capacitor placement with optimum size in radial distribution feeders to reduce the real power loss and to improve the voltage profile. In this paper, the total work is mainly divided in to three sections. In the first section load flow of the system. In the section-II location and size of the capacitors is determined by using Differential Evolution and In the section-III the results are compared with existing method which is proposed by the author.
