Optimal Placement of the DG in Radial Distribution System to Improve the Voltage Profile

P. Sindhu Priya | N. Chaitanya Kumar Reddy

Abstract: One of the modern and important techniques in the electrical distribution systems is to solve the networks problems service availability, high loss and to improve system voltage these can be resolved by accommodating small scaled de-centralized generating stations in networks, which is known as Distributed Generation (DG). DG is an approach that employs small scale technologies to produce electricity close to the end users of power requirement. DG is placed optimally in the system in order to improve system voltage profile, improve service availability, power quality, reliability and reduce loss. The problem of voltage deviation and power loss is mostly addressed in distribution system by growing commercial, Industrial, domestic load day by day. Effective distribution system planning may be required to minimize these problems. By optimal DG placement effective and reliable planning of distribution system is achieved. Optimal DG placement is to determine the location of DG to be installed in the distribution network buses where power losses should be minimum and cost saving should be maximum. SAVI was evaluated before and after placement of DG, to know the number of customer affected due to voltage deviations.
