A Review on Smart Power Generation

Since time immemorial, humans have been requiring and using energy at an increasing rate for their sustenance and well-being. Due to this many energy resources have been exhausted and wasted. Currently we have a variety of power sources, both renewable and nonrenewable sources, but still we are unable to meet our electricity needs. A different ways to generate electricity by using piezoelectric sensor. When human walking, the vibration that generates between the surface and the footstep is wasted. Utilizing this wasted energy, the electrical energy can be generated and fulfill the demand of our electricity. A piezoelectric transducer is used to detect the vibration and this transducer converts the mechanical energy into electrical energy. When we applied a pressure to the piezoelectric transducer it will convert the pressure into electrical energy. The piezoelectric transducer is connected in series-parallel connection. This paper is all about generating electricity when people walk on the floor. This idea is used to convert the weight energy into the electrical energy. In these days energy crisis is the main issue in the world. The main motive of this research work is to reduce the electric crisis.

Energy saving dual-mode recycling of wastewater by MWCNTs-COOK/PDA/PVA assisted composite membrane

Membrane separation technology has been widely used for wastewater purification. However, the commonly used membrane filtration (including dead-end filtration and cross-flow filtration) and distillation are all supported by electric power. It causes great burden to environment, as the electric is still mainly come from thermal power generated from burning non-renewable resource. In this paper, we report a dual-mode functional composite membrane assisted by MWCNTs-COOK and PDA/PVA, where MWCNTs-COOK alignment layer acts as a framework to constructing water nanochannels and PDA/PVA co-deposition layer plays a role as a concrete which improved the integrity of the membrane. It achieved optimal pure water flux of 23.86 L m−2h−1 bar−1 with only 0.1 mg cm−2 of MWCNTs-COOK during cross-flow filtration. Under a light intensity of 100 mW cm2, the composite membrane obtained an average evaporation rate of 1.57 Kg m−2h−1 after 1 h due to the combination of two photothermal materials (MWCNTs-COOK and PDA). More importantly, even after working for 12 h, the membrane still kept an average evaporation rate of 1.52 Kg m−2h−1. And the rejection of organic foulant is up to 99.97 % during long time serving. This indicates that the fabricated composite membrane is prospective for generating clean water from waste solutions which contains foulant. Besides, the integration of electric-driven and solar-driven wastewater purification facilitates multi-application of separation membrane, contributes to electric power crisis, energy saving and multiple service scenarios.

Techno-economic analysis in application of glass solar cell on storey building: A case study of office building

Urban area populated by edifice and storey building can complicate process of electric energy distribution to the middle of city. Citizen reluctance if their settlement passed by transmission network or being built substation, and bigger cost of underground cable than overhead line increases such difficulty level. If there is problem in delivering electric energy, so the city will face electric energy crisis and disrupt society life. One of solution in overcoming that issue is by installation the glass solar cell (transparent solar cell) with thin film material (CdTe) on storey building, which located in the middle of city and its electric energy supplied by PLN. In this study, glass solar cell will be installed in existing building “W” with solar cell area about 6,916 m2. Glass transparency level of study object building is 30%, so by installing same transparency level of solar cell can supply maximum electric energy 897,184 kWh/year or equal to 35% electric energy demand of building. Economic feasibility analysis applied in this study, where NPV is IDR 398,961,738, IRR is 7.47% and the payback period is 11 years, so this technology is feasible to be implemented economically. If considering the tilt and azimuth angle of solar cell installation, instalment in B and C side of building generates smaller electric energy than A and D side. This condition caused by bigger reduction on solar irradiation energy that accepted by B and C site, namely 66.35% for B side and 67.22% for C side. The usage of glass solar cell contributes to deduct greenhouse gas emission, maximum 732,999 kg/year.

Development of the wind power in Brazil: Political, social and technical issues

This paper aims to present a review of the increasing contribution of wind power to the Brazilian electric matrix and an analysis of the main impact on technical, political and social aspects. This work takes into account the state-of-art of the wind power technology, the wind resource potential and the evolution of installed capacity in the country. The institutional programs and the fiscal incentives provided by the Brazilian government are also discussed in this paper, including its impacts on the society. We have reviewed national and international reports and relevant scientific papers to realize this work. The analysis shows that electric crisis in 2001 led the Brazilian government to develop new energy policies that supported the rapid growth of the wind industry from imported technology. Later on in the year 2004, the government mandated that the technology be developed within the country. It is expected that from 2011 (of approximately 1500 MW) until 2021 the installed wind capacity would increase by a factor of 600%. However, the national technology acquisition and development is still incipient. It is important to produce locally wind turbine components and is highly desirable to increase collaboration between industries and universities in the country.

Solar Pump: A Possible Solution of Irrigation and Electric Power Crisis of Bangladesh

The main purpose of this study is to give support irrigation in dry season and reduce the gap between electric power demand and generation by using renewable energy source solar pump. Every year water level is going down 2m/year. As a result scarcity of ground water is increasing, which has a harmful effect on economy. On the other side, electric power demand is growing up for commercial, industrial, domestic, agriculture purpose. To cope up with the demand, dependency on fuel is increasing. If this scenario going on, very soon fuel resource will be finished. And green house gas emission is in dangerous level. Small hybrid system which uses renewable sources as a plant material might be an effective solution of this power crisis and polluted environment. It is high time to give emphasis on using solar energy (pump) in a large scale

Hydro-meteorological Characteristics of Indus River Basin at Extreme North of Pakistan

This paper presents the impact of climate change on three tributaries of Indus River, in four gauge stations, situated in the extreme North of Pakistan i.e. Himalaya, Karakoram and Hindukush ranges. The analysis revealed that change in temperature has a profound influence on the snow/glacial melt in comparison to the mean monthly rainfall. This is because majority of the northern area rivers are faded by the snow and glacial melt and receive a lot of snowfall from winter (Dec-Feb) to pre-monsoon (April-May). In studied rivers 21% of the times the discharge rate remain above the mean in the monsoon period (Jul-Sep), while 64% of the time the discharge is less than the mean in the pre-monsoon (April-May) period. It means that 15% of the time the discharge is in access of 200 to 500% of the mean flow, indicating that a rise in water yield and river discharge rate due to increase in mean monthly maximum temperature. Higher water contribution rate was found in Astor and Indus/Skardu rivers with significant differences compared to other studied rivers.In monsoon period approximately 20% discharge rate was recorded with mean monthly maximum temperature (32°C) and rainfall (17 mm). In pre-monsoon period the discharge rate was (9%) at mean monthly maximum temperature (26°C) and highest mean monthly rainfall (32 mm). This shows that the transfer of climate change signals into hydrological changes is more significant and consistent among the studied rivers. Our findings are useful for hydropower, agriculture, watershed management sectors in the future planning. In countries like Pakistan, water resources estimation under climate change scenario is important for planning especially in dry season for sustainable food security and for operation of hydrological installations regarding electric power crisis.

Energy efficiency, security of supply and the environment in South Africa: Moving beyond the strategy documents

Energy efficiency is one of the most potent and cost effective ways of meeting the demands of sustainable development. It has in fact been referred to as the best energy resource. Way back in 2005 the South African Department of Minerals and Energy (DME) published its Energy Efficiency Strategy in support of some of the objectives enlisted in the 1998 White Paper on Energy Policy. The Strategy set a national target for energy efficiency improvement of 12% by 2015 against the baseline year 2000. The document further predicted that, with a business as usual model of energy usage, at the projected rate of national economic development, there would be a need to invest in new power generating capacity by around 2007. Despite the policy foresight and seemingly enthusiastic efforts, though, the dawn of 2008 saw the country gripped in an electric power crisis, with a capacity shortfall of over 10%. This paper looks at what could have gone wrong, examines energy efficiency policies and measures in other countries and how these lessons could be adopted to the South African context.

Integrated Doubly Fed Electric Alternator/Active Filter (IDEA), a Viable Power Quality Solution, for Wind Energy Conversion Systems

In response to electric energy crisis and power quality concerns, a simple and low-cost variable speed integrated doubly fed electric alternator/active filter (IDEA) for wind energy conversion systems is proposed. The proposed IDEA is capable of simultaneously capturing maximum power of wind energy with fluctuating wind speed and improving power quality, which are achieved by canceling the most significant and troublesome harmonics of the utility grid. Power factor correction and reactive power control are the other two significant features of the proposed technology. The back-to-back current-regulated power converters are employed to excite the rotor of IDEA. The control strategy of rotor side power converter is based on position sensorless field oriented control method with higher power density. A laboratory prototype has been fabricated and tested, and a TMS3202407 DSP-based controller has been used to control the back-to-back power converters. Analysis and experimental results are presented to demonstrate the effectiveness of the proposed integrated IDEA.
