Loss Evaluation of Radial Distribution System

Peddanna Gundugallu | G. Meerimatha

Abstract: This paper gives the simple procedure for calculating the real and reactive power loss of balanced radial distribution system. It also examines the voltage profile of radial distribution systems. To find power loss in each branch and voltages at each bus, simple equations based on backward and forward method are used here. The load flows are evaluated based on current injection method. In this paper, two simple IEEE radial distribution systems have been taken to observe the proposed method. These two systems do not contain any laterals and sub-laterals. In this the loads are constant power loads. Load flow algorithm is given here based on apparent power mismatch.

Keywords: Distribution system, Load flows, Power loss, Voltage profile, Current injection
