ObjectiveAnalytical Approaches for the Optimum placement of
Distributed Generation (DG) Source on a Radial feeder to reduce
power losses.The Optimal site and size for Distributed Generation
Source on a Radial feeder with three different load distributions:
Uniformly distributed load,Centrally distributed load andUniformly
increasing distributed load.Simulation studies to verify the
results obtained analytically for both Radial and Networked
connected systems.
Introduction Electrical power losses in distribution systems
vary with numerous factors depending on system configuration, such
as level of losses through transmission and distribution lines,
transformers, capacitors, insulators, etc. One of the most common
indications of evaluating the efficiency of a power system is the
ratio of power loss to the total generating power. The system is
considered as efficient when the loss level is low. In order to
increase the efficiency of the distribution electrical networks,
loss reduction techniques are drawing more attention.
There are many methods of loss reduction techniques used like
feeder reconfigurationcapacitor placement high voltage distribution
system conductor grading and DG unit placement All these methods
are involved with passive element except DG unit placement. Both DG
units and capacitors reduce power loss and improve voltage
regulation but with DGs, loss reduction is almost double that of
Capacitors.Distributed Generation Distributed generation is an
electric power source connected directly to the distribution
network or on the customer site of the meter. Distributed
Generation or Dispersed Generation (DG) may be defined as a
generating resource, other than central generating station, that is
placed close to load being served, usually at customer site. It may
be connected to the supply side or demand side of meter. It can be
renewable sources based micro-hydro, small Wind turbines,
Photovoltaics(PV), etc or fossil fuel based Fuel cells (FCs),
Reciprocating engines, Micro turbines, etc. In term of size, DG may
range from few KWs to over 100 MWs.
The Distributed Generation (DG) sources are normally placed
close to consumption centers and are added mostly at the
distribution level. They are relatively small in size and modular
in structure. Many approaches have been proposed to solve dispersed
generators placement in distribution systems. Rau and Wan present
the method to identify optimal locations of distributed resources
in a network to minimize losses, line loadings, and Reactive power
requirement by the second order algorithms.Options for small-scale
