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...

the iranian ministry of energy commands the regional electrical companies to install dg resources at 63kv/20kv substations and at the end of 20kv lines. the first and foremost challenge in installing these resources is deciding on the optimal place and capacity of these resources. this paper is aimed to propose an appropriate algorithm for siting and sizing such resources in bakhtar regional el...

restructuring the recent developments in the power system and problems arising from construction as well as the maintenance of large power plants lead to increase in using the distributed generation (dg) resources. dg units due to its specifications, technology and location network connectivity can improve system and load point reliability indices. in this paper, the allocation and sizing of di...

presence of distributed generation (dg) in electric distribution systems provides an attractive new alternative in capacity expansion planning of these systems. in this paper a new model is developed for solving simultaneous placement of hv/mv substations and dg units as a static planning tool. this model aims to minimize fixed and variable costs of planning. constraints related to dgs, substat...

Distributed Generation is the generation of electricity from many small energy sources and is located closer to the user, or customer. This paper presents analytical method to determine the optimal location to place a distributed generation in radial feeder model to minimize the real power loss of the system. The analytical expression and the methodology are based on the power flow method. The ...
