Recently, the power sector has witnessed significant changes on the power distribution systems primarily due to the introduction of smart-grid technology and the incremental use of distributed generation. Distributed Generation (DG) may be defined as the decentralization of power plants by placing smaller generating units closer to the point of utilization, generally up to ten megawatts. The distribution power system is commonly designed for radial power flow, but after the placement of DG, power flow becomes bidirectional. This paper thus focuses on testing different sensitivity indices and using effective methods for the optimal location and sizing of the DG by reducing power losses and improving voltage profile.
