In developing country there is a perpetual growing demand for electricity with an efficient and reliable system of power
supply. Power system is the most complex network with power generation, transmission and distribution system to consumer
loads. The distribution network is an integral part of the power system and acts as an interface to consumer load points. The
network incurs significant losses and voltage drop in the electrical system. Loss minimization and voltage stability are the main
objectives of the distribution network design. This paper introduces optimal branch conductor selection for the microgrid using
unified central load concept for radial distribution systems of microgrid. The conductor size defined by this approach will meet
the maximum current carrying capacity and uphold the acceptable voltage levels of the radial distribution system for rural areas.
The effectiveness of the proposed method in single line diagram is demonstrated through the design of microgrid as an example.
