This paper presents a methodology for multiple distributed generator (DG) placement in primary distribution network for loss reduction. Optimal location for distributed generator (DG) is selected by Analytical expressions and the optimal DG size calculated by IA method and Harmony search algorithm. These two methods are tested on two test systems 33-bus and 69-bus radial distribution systems. T...

In this paper a new approach using Harmony Search (HS) algorithm is presented for placing Distributed Generators (DGs) in radial distribution systems. HS is used for multiple objective planning, to evaluate the DG placement and sizing by considering the power losses and voltage profile as objective functions. HS is operated on 12bus, 15-bus and 33-bus radial distribution system(RDS). Obtained r...

Integration of DG affects the performance of distribution network significantly. DG placement key benefits are power loss reduction and improved voltage profiles which are the objectives in this problem. This paper presents a new efficient te...

In this paper, Direct Search Algorithm is implemented to determine the optimal sizes of Type – I Distributed Generators (DGs) and optimal locations such that maximum possible reduction in real power loss is obtained. Type – I DG injects both active and reactive powers. The algorithm searches for all possible locations in the system for a particular size of DG and places it at the bus which give...

Along with economic growth of countries which leads to their increased energy requirements,the problem of power quality and reliability of the networks have been more considered andin recent decades, we witnessed a noticeable growing trend of distributed generation sources(DG) in distribution networks. Occurrence of DG in distribution systems, in addition tochanging the utilization of these sys...

This paper presents two different but very important aspects of distribution network that’s voltage profile and losses. By keeping in view of these parameters this is to be decided where the distributing generating Units must be placed in distribution network. In the present and future Distributed generation (DG) has its vital importance due to more demand of electricity and renewable nature of...

Distributed generator (DG) placement in distribution system is one of the important tasks for better operation of distribution system. Distribution system has high r/x ratio and high operating current resulting into higher power loss and higher voltage drop. The main objective of this paper is to minimize the active power loss and to improve voltage profile of overall system by optimal sizing a...
