Modeling and analysis of a multibus reticulation network with multiple DG. Part I. Electrical losses

A significant growth in the utilization of autonomous- and distributed power sources deployed at subtransmission (132 - 22 kV) and reticulation levels (<22 kV). In stand-alone or grid connection notations has been seen in many electricity industries across the world. With electricity industry reform, an open access regime is a standard policy governing the transmission grid, thus providing for full competition at generation and distribution end of the electricity delivery value chain. It has become necessary to investigate the technical and economic impact future connections of distributed generators will have on electric power distribution networks, and evaluate some of these effects of power sector deregulation. This paper presents the modeling and analysis of a multibus reticulation network model with multiple distributed generation (DG) injection. Results for steady-state dynamic performance and optimum location of generator for minimum network losses are presented.
