Abstract: In recent few years, the implementation of distributed generator into a distribution system has been increasing rapidly in many parts of the world, due to the liberalization of the electricity markets, constraints on constructing a new distribution network, transmission lines and environmental concerns. Technical advancement in small generators, power electronics and energy storage devices have promoted the use of DG unit. DG units, basically, are small generating units, which are placed closer to the point of consumption. The utilization of a DG unit placed on-site of the load demand in the system which provides evident power losses reduction, stability improvement, and voltage profile improvement along with accelerating sustainability of environmental issues. Distributed Generation is the power generation at the point of consumption. Instead of providing power centrally, generating the power on-site decreases the cost, less complex, independent, and efficient transmission and distribution. Using this system, some of the controls such as distributed generation, distributed telephony i.e. using mobile phone shifts to the consumer. It is, basically an electric power source connected to the distribution system directly. Before the installation, its effects on line losses, voltage profile, short-circuit current, amount of harmonics injected and the reliability should be computed. In order to obtain the efficient compensated system factors like type of network, best technique used, no. and capacity of units to be used, best location etc. should be taken into account. This thesis work focuses on the minimization of real power loss and voltage profile improvement of a radial distribution network using suitable DG units. Here, a 33-node radial distribution system has been used as the test system and Harmony Search Algorithm has been implemented to find the optimal location of DG unit and Loss sensitivity Method has been used to obtain the optimal size of DG in order to reduce real power losses and improve voltage profile.
