Optimal Placement of DG Based On Voltage Stability Index and Voltage Deviation Index

Abstract

Objectives: In Modern world power production and its efficient usage defines the development of the country. In distribution system of an electrical network due to the influence of loads, voltage profile and losses are to be focussed a lot. In order to avoid the maximum losses and to maintain the voltage profile usage of Distribution Generator (DG) plays a major role in the network. Statistical Analysis: Since we have to use an appropriate place and size of DG, a measuring technique based with index through which optimal size and place can be identified and is implemented in the work. Findings: This Paper focuses on reducing power losses by accurately giving the location and size of DG based on two indices (a) Voltage Deviation Index (VDI) (b) Voltage Stability Index (VSI). Results such as power losses, location, size and cost of DG are obtained for both initial configuration and Feeder reconfigured state for IEEE 33 and 69 bus systems were listed. Applications: These analysis help us in installation of Different types of DG to present network where demand side management has to be followed.
