Abstract: Distributed Generation (DG) also known as dispersed generation is small scale generation units directly coupled with the distributed system. There has been great interest in the installation of distributed generation sources close to the consumer load center. The DG technologies comprise of both conventional and non-conventional sources of energy to generate power in order to satisfy the demand of ever rising energy demand. Optimum position and size of DG units can aid the performance of active power system network. Integration of DG units of optimum capacity at ideal locations improves the voltage profile of the system and minimizes the active and reactive losses of the system. In this paper, state of the art techniques for optimum placement and sizing of DG have been suggested. The paper provides an overview of the various methods implemented for determining optimal location and capacity of DG units to maximize the benefits of DG units in the system network
