15-16-001 Controlled Distribution of Solar Power/Energy to Multiple Users from a Single Power Source Show Abstract PDF
  M Junaid Khan, Jahanzaib Hassan, Nabeel Ahmed, Yasir Arrfat
Solar power is on demand due to depleting resources, high energy tariffs and technological advancements in solar related technologies. One of the common impediments in its enhanced use is the cost involved which is still higher for a general consumer. The hardware/equipment used in solar power applications is much expensive hence every effort to lower the cost is welcomed by the industry and user. This research has aimed to address a striking problem of local solar industry where it was desired to have a control mechanism to provide predefined power to multiple users supplied from a single solar source. This objective stems from the fact that multiple sources for many users involve manifold hardware, cost and maintenance. The solution to the research problem is based on designing of a feedback control circuit which monitors the instantaneous power and the energy units (Kwh) provided to each consumer. The problem is posed as a traditional sensing, feedback, comparison and control problem, where a reference value of units (Kwh) is set as the external input in terms of command following. The current value of units is measured by energy integrated circuits (ICs). The comparison and generation of control input is implemented using microcontroller programming. The control of consumed units and instantaneous power is done in a unified fashion. The novelty of this research lies in the fact that no such product has existed in the local and abroad market, especially for the DC power sources. Further the research aimed to have a cost effective product using state of the art technologies.
15-16-002 A Study on Low Cost Electrification Using Solar Energy – a Field Work Show Abstract PDF
  R. Sankar, P. K. Jery Althaf, and S. Sreevas
From a path breaking innovation, electricity has grown into one of the most important factors helping us to sustain civilization today. The entire world economy is dependent on technology today. Yet, certain remote areas are deprived of this basic amenity, either due to the lack of concern from the authorities or due to the unawareness about harvesting locally available resources. In this paper, the challenges faced by one such area are identified and the issue is solved by utilizing alternate energy source. This paper describes how rural electrification can be implemented in a cost-effective manner without compromising efficiency. The area under study is located farthest from the existing power grid and the high expenditure that has to be incurred in its electrification withdrew the authority from this task. However the project team formed under the Local Integrated Network of Kerala IEEE Students identified that the solar energy can be harvested in the area. All the project parameters were analyzed in detail and thorough research was done on the land and its inhabitants. Underground cables were chosen as the means of transmission. The project implemented provided electricity for basic lighting devices. The project can be viewed from a global perspective, as the characteristics of the area selected are identical to similar non-electrified regions around the world.
15-16-003 Smart Grid for a Sustainable Future Show Abstract PDF
  G. M. Shafiullah*, Amanullah M. T. Oo, A. B. M. Shawkat Ali, Peter Wolfs
Advances in micro-electro-mechanical systems (MEMS) and information communication technology (ICT) have facilitated the development of integrated electrical power systems for the future. A recent major issue is the need for a healthy and sustainable power transmission and distribution system that is smart, reliable and climate-friendly. Therefore, at the start of the 21st Century, Government, utilities and research communities are working jointly to develop an intelligent grid system, which is now known as a smart grid. Smart grid will provide highly consistent and reliable services, efficient energy management practices, smart metering integration, automation and precision decision support systems and self-healing facilities. Smart grid will also bring benefits of seamless integration of renewable energy sources to the power networks. This paper focuses on the benefits and probable deployment issues of smart grid technology for a sustainable future both nationally and internationally. This paper also investigates the ongoing major research programs in Europe, America and Australia for smart grid and the associated enabling technologies. Finally, this study explores the prospects and characteristics of renewable energy sources with possible deployment integration issues to develop a clean energy smart grid technology for an intelligent power system.
15-16-004 An Overview of Smart Grid Technology: Development and Opportunities Show Abstract PDF
  Tausif Ali, Ahmed Al Mansur, Zubaeer Bin Shams, S.M. Ferdous, Md. Ashraful Hoque
Generally smart grid is a modern technology of power system which can convert the whole power system in to digital format. In brief, a smart grid is the use of sensors, communications, computational ability and control in some form to enhance the overall functionality of the electric power delivery system. A system becomes smart by sensing, communicating, applying intelligence, exercising control and through feedback. For an ideal power system, this permits several functions which can optimize in the combination of the use of bulk generation and storage, transmission, distribution, and consumers. It can fulfill the goal which can ensure reliability and optimization of the use of Energy. It will also keep the environment free from pollution, save the assets, minimize the cost, easy operation against all hazards, maximum possibility to keep out from danger, provides power quality for 21st century needs. The focus of this paper is to familiarize with smart grid perspective to Bangladesh. The conception of smart grid is almost new is Bangladesh. The whole power system network in Bangladesh is very elaborate and complex but primitive. To reduce this complexity and improve the performance of the system, smart grid can be a better solution. Load-shedding is a common phenomenon in Bangladesh. It can be solved by smart grid technology. As it can automatically detect, calculate and distribute electricity as per load requirements, it reduces the system loss and at the same time a certain amount of electricity from the grid would always be available at each consumer side even at the time of load shedding. Bangladesh can be greatly benefited by using this technology. The main objective of this paper is to discuss the necessity of smart grid for the perspective of Bangladesh which may be an effective solution to overcome the recent power crisis.
