Abstract—Conventional Transmission and Distribution systems do not envisage at present any generation on consumer side. However, with the enactment of Indian Electricity Act 2003 and due to the major changes in the Power Sector and the fast move towards liberalization of the energy markets, utilities are inclined to install small capacity generating units to distribution systems. Integration of small capacity generators at load points in the existing electrical network will have impact on voltage regulation, losses, reserve capacity of network etc. In this paper, Renewable Distributed Generators (RDGs) are introduced at suitable locations of a heavily loaded distribution network to study the impact on minimization of distribution losses. Case study has been performed on a real 4.2 MVA distribution system of a particular area of Gujarat state, India. A methodology has been developed for citing the RDGs at a suitable location in the Network.

Index Terms—Distribution losses, forward / backward sweep, renewable distributed generation, Voltage profile.
