The Distributed Generation(DG) has created a challenge and anopportunity for developing various noveltechnologies in power generation. Theproposed work discusses the primaryfactors that have lead to an increasinginterest in DG. DG reduces line losses andincreases system voltage profile. Theproposed work finds out the optimal valueof the DG location and capacity to beconnected to the existing system usingmodified shuffled frog leaping algorithm(MSFLA) thereby maximizing the systemvoltage profile and reduces line losses.Benefits of employing DG are analyzedusing Voltage Profile Improvement Index(VPII) and Line Loss Reduction Index(LLRI).The proposed method is tested on astandard IEEE-70 bus radial distributionsystem and the results of the simulationcarried out using MATLAB7.0 are foundto be encouraging. The method has apotential to be a tool for identifying thebest location and rating a DG to beinstalled for improving voltage profile andreduces line losses in an electrical powersystem.
