An artificial neural network (ANN) based maximum power point tracking (MPPT) algorithm has been developed. The proposed ANN based controller has the ability to estimate wind speed by tracking the maximum power point (MPP) and the optimal rotor speed with very low error compared to the conventional MPPT methods. The algorithm is based on two series neural networks, one for wind speed estimation and...
Present development of the world is measured by the amount of energy consumption. Energy of today world is generated from conventional energy sources mostly which are decreasing day by day. Moreover, these conventional energy sources causes pollution and responsible for global warming of the world. To solve these problems, researchers are trying frequently to explore new sources of energy which are...
Implementation of wind turbines has been increased significantly because of its availability, easy and low cost generation around the world. Meanwhile in Bangladesh wind energy conversion is a very recent concept compared to other renewable energy conversion techniques and yet in many places research is going on to measure and analysis the wind velocity. The primary target of this research is to determine...
The outer rotor permanent magnet alternator (PMA) is superior for small wind turbine system due to its robust, little maintenance and low cost configuration. In this research, the design and performance analysis of a radial flux outer rotor type PMA used for gearless, extremely low-speed, and small capacity wind turbine system has been discussed. The design has been simulated to analyze this PMA....
After the golden era of silicon, nowadays compound semiconductors from III-V group is extensively studied to observe their application in electronic as well as in other field. Solar cell which is providing alternative source in our industries, houses and laboratories. Researchers are now trying to find out new features by using these inorganic materials based solar cell which can easily be paved the...
Walking acts as an authentic link for intermodal transfer in major activity centers and helps to fulfil recreational and utilitarian trips in a city. To assess the condition and pattern of walking, walkability assessment is the primary option. In the last decade a large number of literatures in urban planning, public health and transportation have analyzed the role of the built environment on physical...
Energy crisis is the most critical infrastructure constraint in Bangladesh's economic growth. Limited resources for generation of electricity is one of the major reason behind that. It is happening because of the limitation of technology in the field of electricity. Though renewable energy is introduced, the impact of this new technology is not significant. This is why this paper introduces a mechanism...
In today's world the demand of energy is incredibly high and non- renewable resource such as ore, fossil fuel and nuclear fuel are not sufficient to meet this demand. Eventually renewable energy is a better choice. There is an increasing trend of using solar cell in the industry as well as to household appliance because solar energy is expected to play a prominent role in future smart grid as a distributed...
To ensure the safety of environment a major challenge to the vehicle manufacturer is the emission rate of vehicle. Emission of environment polluting particles especially CO2 from conventional vehicles is a direct threat to the environment. As global vehicle market are expanding day by day so this high rate of emission is already a nightmare to the environment specialist. That's why some of green technologies...
Power crisis is the most concerning problem in Bangladesh for the past few decades. Despite a lot of attempts by the Bangladesh Government, due to increasing population & rapid industrial growth, this problem seems to be augmenting day by day. Energy preservation is the result of financial capital increase of the country and also increases the environmental values. Being a developing country,...
Power quality is one of the most significant current discussions in electric energy distribution systems. The issue of harmonics has been a controversial and much disputed subject within the field of power quality. Harmonic current originates from all types of nonlinear loads. This paper attempts to show the impacts of rapidly increasing share of nonlinear loads on harmonic distortion of urban distribution...
This paper reviews the prospects of available renewable energy resources along with various private and government future project plans to incorporate renewable energy sources and its potentials in perspective of Bangladesh. In an arising country like Bangladesh demand for energy will be burgeoning. Present day, in Bangladesh dearth of energy is ubiquitous and near about 70% of its population is excluded...
Among available technologies for energy production from renewable sources, ocean wave energy and tidal power could give a significant contribution to develop a more sustainable energy system. Tidal power is one of the best renewable energy sources in coastal area and becoming popular around the world due to its own facilities. Ocean wave energy can play a vital role for producing electricity as new...
In our research work electrical characterization with different generation of solar cells depending upon the emergence as- First Generation: Mono and Poly-crystalline Silicon, Second Generation: Thin-film Solar Cell, Third Generation: Full Spectrum Utilization with comparative efficiency study of different solar cells is investigated. Besides, major part of our research is Multi-Junction Solar Cells...
The polycrystalline ultra-thin cadmium telluride (CdTe) is familiar as the potential solar cell material for its higher efficiency, cost-effective, cell stability and clean generation of solar electricity. In this study, a numerical analysis has been performed utilizing AMPS (Analysis of Microelectronic and Photonic Structures) simulator to examine the cell performances (Voc, Jsc, FF and conversion...
Presents the introductory welcome message from the conference proceedings. May include the conference officers' congratulations to all involved with the conference event and publication of the proceedings record.
Despite the growing popularity of smartphones, it's extensive power consumption is still now a burning issue. In this regard, we propose and evaluate a system of CPU power consumption reduction which supports Dynamic Voltage and Frequency Scaling (DVFS) and User Driven Frequency Scaling (UDFS) at the same time. At first, a DVFS is used to scale the frequency level continuously based on loads present...
A smart grid is an electricity network based on digital technology that is used to supply electricity to consumers via two-way digital communication. This system allows for monitoring, analysis, control and communication within the supply chain to help improve efficiency, reduce the energy consumption and cost, and maximize the transparency and reliability of the energy supply chain. The term “smart...
