In the context of the smart grid, energy management systems at household level has a vital impact on distribution grid. PV based energy systems at household level become more popular day-by-day. Thus scheduling residential energy storage device is necessary to optimize technical and market integration of distributed energy resources (DERs), especially the ones based on renewable energy. The first step of electricity consumption forecasting at individual household level is used to achieve proper scheduling of the storage devices. Then an intelligent agent based controlling technique is proposed to make sure the financial benefits of end-user as a part of energy management system. In this paper the forecasting ability of Artificial Neural Network (ANN) is evaluated to capture the daily electricity consumption profile of an individual household.

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 wind prospects of Teknaf coastal area in Bangladesh by developing a statistical analysis of wind velocity at that region and to propose the design of blades for a low-speed wind turbine using theoretical analysis of power availability and wind velocity at different heights. The design approach can be applied successfully to develop a low-speed wind turbine's pole and blade construction.

This paper proposed a conceptual design and economic analysis of a distributed storage based DC micro grid system for rural area electrification of Bangladesh. In this design we has taken an average load consumption about 34.3kWh including the rural household load and irrigation facility with seasonal load variation. After that we have estimated required specification of DC micro grid components such as solar PV, micro grid charge controller, battery, distribution system etc. Moreover, we have also shown the cost analysis of our proposed micro grid system. Cost analysis estimated about 17.80 BDT/kWh electricity cost with seasonal irrigation facility. It is argued that the developmental activity should be chosen in such a way that it matches with the seasonal variation in insolation and load demand may keep the energy cost to a minimum.

The necessity of information and communication technology beggars description. But in developing world, proper ICT facilities have not been achieved yet, especially, in the rural or remote areas. In this paper, an incentive has been presented to develop a sustainable peer to peer network for those areas. The connected peers will be able to share important information shared without the requirement of any special central server. For better communication and access to internet, directory center can be connected to broadband (if available) or mobile network based internet. Since energy crisis is a major problem in developing countries, alternative power system with renewable sources has been proposed. The deployment of energy-efficient ICT with the optimization of renewable energy also sets the way towards green growth and sustainable development.

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 efficiency) of ultra-thin CdTe solar cell. During the research, reduction of CdTe layer was done in the proposed cell and found that 1μm absorber layer is enough for acceptable range for cell conversion efficiency. The possibility of this ultra-thin CdTe absorber layer was examined, as one with 100 nm ZnTe back surface field (BSF) layer to minimize the recombination losses at the back contact and to reduce the barrier height in the valence band of the proposed cell. Higher conversion efficiency of 22.53% (Jsc = 24.28 mA/cm2, FF = 0.875, Voc = 1.06 V) has been achieved with only 0.8 μm of CdTe absorber layer along with 100 nm ZnTe BSF where as conversion efficiency is 18.68% (Jsc = 21.47 mA/cm2, FF = 0.85, Voc = 1.02 V) without BSF layer. Moreover, the proposed CdTe solar cell showed better stability as the normalized efficiency of the proposed cell linearly decreased with the increasing operating temperature at the gradient of -0.16%/°C.

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 to produce green electricity from human wastage energy. In this mechanism the pressure energy from the movement of human body is used to harvesting electricity using gymnasium bicycle. This paper also presents a field survey on the human and gymnasium at Chittagong city to find out the feasibility of this mechanism. A hardware implementation has been done to produce electricity through the use of gymnasium bicycle. A detailed cost analysis has also been done to find out the economic generation of electricity. Actually the authors are trying to introduce such a mechanism through which the electricity problem of Bangladesh will be reduced significantly.

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 source of renewable energy to the off-grid power connection in isolated areas, namely Sandwip, in Bangladesh. Ocean wave energy having environmental friendly is the only sustainable solution of secure energy system in coastal area. Bangladesh has a huge potential of tidal power at different locations. It has a long costal area with 2-8 m tidal head/height rise and fall. This height is sufficient enough to produce power. So, tidal power has a bright future in Bangladesh. It can reduce the present energy crisis and improve the social, environmental and economic perspective of Bangladesh. But effective measures on this issue have not been considered sincerely. In this paper we propose a system which can be generated electricity by using amplitude of Ocean wave which may be an effective solution to overcome the recent power crisis in Bangladesh.

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. The elementary configuration like material types, magnet types and additional electrical and mechanical parameters are studied, and the performances parameters of PMA are improved by changing these elementary electrical and mechanical parameters or some other related factors such as reducing the cogging effect. Cogging torque has been reduced by employing fractional slot per pole, width of slot opening, mounting of the magnets. Also the slot shape has been custom-made to increase the efficiency. The slot fill factor was improved by using different wire diameter used as winding coil. This improvement has been played a great role to reduce copper losses thereby improving the thermal condition of the slot. Finite element analysis (FEA) method was used to analyze this PMA in order to test the real time performance simulation with loss and cogging torque calculation. By taking all these considerations into account, higher efficiency from the outer rotor arrangement with minimum losses has been achieved.
