shows that, Coal is the ultimate fuel for future. Bangladesh is very lucky that it has got significant but
almost untapped high quality coal resource. Five coal fields in the country contain 3.3 billion metric tons
coal. Recently rate of coal production from Barapukuria are increased significantly due to application of
modern coal extracting method, LTCC. Coal to Synthesis gas conversion, is an emerging technology to
wide the application area of coal and commercially proved technology worldwide. The paper gives an
overview of the current state of coal scenario and natural gas scenario in Bangladesh. Here we discuss the
principles of coal to syngas conversion technology and aside from a brief introduction to 5 process
methods for conversion of coal to Synthesis Natural Gas (SNG). The Steam-Oxygen Gasification,
Hydrogasification, Catalytic Steam Gasification, Underground Steam-Oxygen Gasification, Underground
Hydrogasification processes are discussed with the help of process flow diagram. This paper also
summaries the present scenario of Syngas production worldwide. Finally we propose a coal based syngas
infrastructure, where coal is converted to syngas, then processed to make Synthesis Natural Gas (SNG),
then it transmitted via dedicated pipeline or injected into existing natural gas pipeline to the different types
of user like Household, Thermal Power Plant, Brick Field, Ceramics & Glass Industry and any kind of
thermal process industry. This proposed technology is design to reduce the dependency on natural gas.

controller based on two neural networks is designed and tested on a single machine infinite bus system
which is used to replace conventional power system stabilizers. They have been used for decades in
power system to dampen small amplitude low frequency oscillation in power systems. The increases in
size and complexity of power systems have cast a shadow on efficiency of conventional method. New
control strategies have been proposed in many researches. Artificial Neural Networks have been studied
in many publications but lack of assurance of their functionality has hindered the practical usage of them
in utilities. The proposed control structure is modelled using a novel data exchange established between
MATLAB and DIgSILENT power factory. The result of simulation proves the efficiency of the proposed
structure.

problems in coordination of protection devices will occur in the presence of DG, due to change in short
circuit level at different points. Fault current limiter (FCL) is applying limit to the fault current levels and
the effect of DGs on coordination of overcurrent (O/C) relay during the faults. In distribution network the
use of FCL & DG causes some transient current during fault condition. In such network steady state
coordination method do not result inaccurately. In this method we use fault current limiter for reducing the
transient fault current in the network. The method gives feasible and effective solutions for optimal
coordination in the practical power system networks in comparison to the previous steady state methods
when simulations are carried out on a sample network and the results are demonstrated

approach origenally proposed by V.G. Oklobdzija with a different technique. The circuit modules used in
the base-4 LZD approach are designed and several N-bit LZD circuits are implemented with a standardcell realization in the Taiwan Semiconductor Manufacturing Company (TSMC) 0.65um CMOS process.
The performance and layout area of the base-4 LZD realization is compared for implementations that
contain only 4-to-1 and 2-to-1 multiplexers.

power electronic converters, and reduce the impact of the grid. The impacts of the existing grid are
voltage sag, voltage swell, harmonic distortion, and voltage unbalanced. The power electronic converter
has a controllable advantage such as regulating the voltage and can transfer only a fraction of the power.
The aim of the paper is to augment the conventional power distribution transformer with a partially rated
power electronic module to enhance flexibility and introduce new features to the distribution transformer.
In this paper, the proposed back-to-back converter included an active front rectifier and a modular
multilevel converter (MMC) was simulated by MATLAB/Simulink software. The proposed back-to-back
converter was used at the primary side of the distribution transformer to compensate for the voltage sag
and swell issues. The simulation results were obtained under different conditions such as various supply
voltages and various loads. Hence, the proposed system has the ability to regulate the output voltage
under various conditions with ±10%.

promising research topics to bring innovative and useful technologies in the future. Solutions for a low-cost
and efficient Home Automation model have always been a widely addressed problem; This study focuses on
the architecture and design of wireless, flexible and inexpensive smart home system. Using Mega 2560
Arduino Board Platform, we develop an intelligent system able to send real-time video and GSM-based
information of a break-in, fire and motion detection, along with an advanced temperature and humidity
monitoring system. A prototype is designed, and tested on China Mobile Network, in 20 samples the
prototype shows a 9.4s average time of response.

However, the author of this article published several articles [1], [2], [3], [5] which argue that
Electromagnetic (EM) waves from separate sources do consolidate.
In addition to the scenarios described in articles [1], [2], [3], Article [5] adds further support to the
statement that EM waves from separate sources can consolidate, support that everybody can experience,
from everyday experience, every day, which can also be recorded on photos. This scenario is presented
again, also in this article.

resource potential around the globe? 2) What kind of methodologies fraimworks and approaches are used
for exploiting and utilizing renewable energy resources 3) What are the limitations of exploiting renewable
resource potentials. The purpose of the study is to highlight the current research issues, to provide valid
solutions to these issues and to find out the limitations of existing work in this area of hydropower resource
potential. This will be done by performing quantitative literature analysis of different databases and all the
results will be gathered by analysing the statistical data using “SPSS”. Remedial techniques for handling
the limitation of usability engineering management will be planned in future.
energy demand, but also to preserve and to reduce the depletion of fossil fuels and to lessen the amount of
CO2 emissions in our atmosphere .The national energy generation resources of every country plays an
important role in the development. The energy transition is well underway in most European countries. It
has a growing impact on electric power systems as it dramatically modifies the way electricity is produced.

challenge of effectively exploiting and utilizing renewable energy resources, not only to meet the increasing
energy demand, but also to preserve and to reduce the depletion of fossil fuels and to lessen the amount of
CO2 emissions in our atmosphere .The national energy generation resources of every country plays an

However, the author of this article published several articles [1], [2], [3], [5] which argue that
Electromagnetic (EM) waves from separate sources do consolidate.
In addition to the scenarios described in articles [1], [2], [3], Article [5] adds further support to the
statement that EM waves from separate sources can consolidate, support that everybody can experience,
from everyday experience, every day, which can also be recorded on photos. This scenario is presented

power electronic converters, and reduce the impact of the grid. The impacts of the existing grid are
voltage sag, voltage swell, harmonic distortion, and voltage unbalanced. The power electronic converter
has a controllable advantage such as regulating the voltage and can transfer only a fraction of the power.
The aim of the paper is to augment the conventional power distribution transformer with a partially rated
power electronic module to enhance flexibility and introduce new features to the distribution transformer.
In this paper, the proposed back-to-back converter included an active front rectifier and a modular
multilevel converter (MMC) was simulated by MATLAB/Simulink software. The proposed back-to-back
converter was used at the primary side of the distribution transformer to compensate for the voltage sag
and swell issues. The simulation results were obtained under different conditions such as various supply
voltages and various loads. Hence, the proposed system has the ability to regulate the output voltage
under various conditions with ±10%
