3. INTRODUCTION

4. Background to the Study
The advantages, needs and use of electrical energy in the world today cannot
be overemphasized. Every country depend on electrical energy in order to
achieve economic, environmental and social growth and sustainability.
According to Vishwanath Hegde et al., The world electricity industry in this
21st century is faced with challenges and diculties that demand immediate
attention towards growth, expansion and energy management. They assert
that most of the electricity supply companies are facing shortage of electrical
energy. Therefore to make up for these shortages of electrical energy,
reducing losses and hence saving energy becomes the rst and foremost
important step as a part of demand side management[Vishwanath Hegdeet al., 2002].

5. State of Art and Literature Review
Amaranathaet al.2015
The power loss on distribution transformers can account for a considerable
portion of the overall loss. Here, Amaranatha and others propose the method
for optimal placement of capacitor banks to the distribution transformers to
reduce power loss[Amaranatha D.et al., 2015].
Masoudet al.2019
Masoud and his partners asserted that the optimal size, type, and location of
automatic switches in a power distribution system are determined by
minimizing the objective function using the particle swarm optimization
(PSO) algorithm. They insinuated that the eectiveness of such proposed
method was tested by implementing it on two feeders of Isfahan's electric
distribution network and their results indicated the eciency and
applicability of the method they proposed[Masoud A.et al.2019].

6. State of Art and Literature Review
Sridharet al.
This research theme purported that Fault Location, Isolation, and
Restoration (FLIR) is the key concept of Distribution Automation (DA) in
today's Smart Grid arena. They proposed novel hybrid Multi Agent System
(MAS)fault restoration solution that uses both centralized and decentralized
concepts for fault restoration on feeders with Microgrids[Sridhar C.et al.].
Syedet al.2017
Syed and his team presented a new planning approach based on voltage
stability index (VSI) together with improved loss minimization (LM)
formulations. The method was employed for application of distributed
generation (DG) unit placement (location and size) in a loop distribution
network (LDN). They Initially employed VSI relationship for equivalent
loop model to nd out potential locations for DG placement in LDN. Later,
they derive the loss minimization formulations and loss minimization
conditions (LMC) on the basis of an equivalent electrical model of LDN, for
single and two DGs operating at various power factors, respectively
[Syed A.et al., 2017].

7. Research Gap
Optimal placement problems of electrical devices in distribution power
systems have attracted greater attention from researchers in literature over
the past years. Therefore, in the last 60 years, a wide range of solutions and
methodologies have been developed for optimally allocated shunt capacitors,
generation sources, switches, transformers, and many other electrical
devices in transmission, distribution, and microgrid systems.
This large number of methods are paramount to place any electric device
with the ability to inuence any network parameter.
However, this research now concentrates on how these works have impacted
the eciency of radial distribution networks. To track down this impact, a
historical literature review of the optimal placement eorts of electric
devices in power systems is proposed.
Additionally, the existing research works are reviewed from the perspective
of their considered device types, design variables, network type, and
objective function.

8. Limitations/Delimitation
Limitations
The main limitations of this research are those of collecting real data from a
real-life radial distribution system. Furthermore, the current research does
not go into other types of networks such as loop distribution power system.
Delimitation (Scope)
The scope or delimitation of this work is to determine an optimal position
for a distribution transformer centre by using a MATLAB model of a radial
distribution power system.

11. METHODS

12. METHODS AND PROCEDURES
Research Design
This research will make use of theQuantitative ResearchandAnalytical Researchdesigns in which
numerical data will be collected during the quantitative phase and this data will be analyzed during the
analytic phase. The analyzed data will use already conrmed data as a basis for the research and will
then critically evaluate the material used in carrying out the research.
Instrumentation
The required apparatus for this research is a Personal Computer (preferably a Laptop) equipped with
MATLAB
®
software.
Procedure/Processing
The Radial Network model will be designed in MATLAB/Simulink and simulated. Then the objective
function which will be modeled mathematically will be optimized using MATLAB/Cf Tool.
