Distributed generation (DG) can be integrated into distribution systems to meet the increasing load demand. This paper discusses the sizing and sitting issue of single DG placement in radial distribution systems using distflow technique. The main objective of the work is to minimize the active and reactive power loss and enhance voltage profile of overall system. The effectiveness of the proposed...
The influence of Distributed Generation (DG) in distribution network is emphasized because of its promises to supply reliable and better quality of electric power to consumers. Moreover, changing economical and regulatory environment are encouraging electrical utilities to concentrate on DG. A Particle Swarm Optimization (PSO) based formulation of optimization problem to facilitate determination of...
The paper presents voltage stability margin (VSM) of radial distribution network by considering a unique reactive loading index for composite loads. It is shown that the branch, at which the value of reactive loading index is minimum, is considered to be the weakest branch of the system. Then, the voltage stability margin (VSM) of the feeder is selected heuristically. It is the product of reactive...
This paper presents Loading Status for all Branches in chronological order at different Conditions in Radial Distribution Systems using Reactive Loading Index. Although under different loading conditions for all the branches the identified weakest branch remains same but the corresponding loading at different branches in chronological order has been categorically identified for different values other...
This paper presents a unique method to determine the weakest branch or the overstressed branch in a distribution network. This radial feature of the network has been fully exploited to establish the concept of local voltage stability indicator in terms of reactive power. The effectiveness of the proposed method has been successfully tested in 12 bus radial distribution system and the results are found...
