Thevenin's Network Analysis for Radial Distribution System with Load Models

This paper presents thevenins network formation for radial distribution system. Here backward and forward sweep method has been used for load flow solution. Here load flows have to run twice. First time, normal load flows has to be executed. Second time, load flows can be executed by equating sensitive bus power to zero. The main objectives of this paper have given below. (1) To find thevenins voltage (2) To find thevenins impedance For radial distribution system with load models a) Constant power loads b) Constant current loads c) Constant impedance loads. Here 10-bus and 15-bus radial distribution systems have been used for evaluating proposed objectives.
