Power Loss Reduction in a Radial Distribution Network Using Distributed Generation

Reduction in real power losses and improvement in voltage profile are two major objectives of Distributed system utilities. For this purpose, placement of step-size distributed generations (DG) in radial distribution system is used. In this paper, IEEE 33-bus and 69-bus Radial Distribution System (RDS) are tested for same purpose, using load flow solution in MATLAB environment which is based on BIBC matrix formulation. After performing the load flow, a DG is placed on the bus having worst voltage profile, repeatedly. After the analysis of test results it is concluded that reasonably lower losses and improved voltage profile of a distribution system can be obtained by placing DGs of suitable sizes and at proper locations in the system.
