Development Without Energy? Assessing Future Scenarios Of Energy Consumption In Developing Countries, Jan Steckel, Robert Brecha, Michael Jakob, Jessica Strefler, Gunnar Luderer
Development Without Energy? Assessing Future Scenarios Of Energy Consumption In Developing Countries, Jan Steckel, Robert Brecha, Michael Jakob, Jessica Strefler, Gunnar Luderer
Robert J. Brecha
We analyze the relationship between economic development and energy consumption in the context of greenhouse gas mitigation. The main contribution of this work is to compare estimates of energy thresholds in the form of minimum energy requirements to reach high levels of development with output projections of per capita final energy supply from a group of integrated assessment models (IAMs). Scenarios project that reductions of carbon emissions in developing countries will be achieved not only by means of decreasing the carbon intensity, but also by making a significant break with the historically observed relationship between energy use and economic growth. …
Optimal Configuration Assessment Of Renewable Energy In Malaysia, Ahmed Haidar, Priscilla John, Mohd Shawal
Optimal Configuration Assessment Of Renewable Energy In Malaysia, Ahmed Haidar, Priscilla John, Mohd Shawal
Dr Ahmed Mohamed Ahmed Haidar
This paper proposes the use of a PVewindediesel generator hybrid system in order to determine the optimal configuration of renewable energy in Malaysia and to compare the production cost of solar and wind power with its annual yield relevant to different regions in Malaysia namely, Johor, Sarawak, Penang and Selangor. The configuration of optimal hybrid system is selected based on the best components and sizing with appropriate operating strategy to provide a cheap, efficient, reliable and cost-effective system. The various renewable energy sources and their applicability in terms of cost and performance are analyzed. Moreover, the annual yield and cost …

Smart Control Of Upcq Within Microgrid Energy System, C Benachaiba, Ahmed Haidar, O Habab, O Abdelkhalek
Dr Ahmed Mohamed Ahmed Haidar
One of the most popular issues in the future power distribution is the quality improvement of microgrid and the development of smart grid (SG). Many applications operating at the microgrid level can be considered as smart grid functions. This paper proposes the application of Fuzzy Logic (FL) technique within microgrid energy system based on the most modern power conditioning equipment devices such as Unified Power Quality Conditioner (UPQC). This technique is working together with the microgrid to track the disturbance of the smart grid and improve the quality of the system with a high flexibility. Furthermore, a control methodology developed …
Hydrogen Energy Storage For A Permanent Magnet Wind Turbine Generator Based Autonomous Hybrid Power System, Nishad Mendis, Saad Sayeef, Kashem Muttaqi, Sarath Perera
Hydrogen Energy Storage For A Permanent Magnet Wind Turbine Generator Based Autonomous Hybrid Power System, Nishad Mendis, Saad Sayeef, Kashem Muttaqi, Sarath Perera
Associate Professor Sarath Perera
The Performance of a novel hybrid Remote Area Power Supply (RAPS) system consisting of a Permanent Magnet Synchronous Generator (PMSG), fuel cell system, electrolyser and synchronous condenser is investigated in this paper. The fuel cell system is used to provide power during under-generation scenarios whereas the electrolyser absorbs excess power during over-generation conditions. A synchronous condenser is incorporated into the RAPS system to provide better reactive power and inertial support. Individual controllers for each system module have been developed and implemented. A control coordination methodology is established with a view to regulate the active and reactive power balance of the …

A Comparative Study Of Vehicle Drive Performance And Energy Efficiency, S. Abdul Rahman, P. D. Walker, Nong Zhang, Jianguo Zhu, Haiping Du
Dr Haiping Du
In this paper, two types of increasingly more efficient and greener vehicles are analyzed and compared. These vehicles are: a proposed conceptual seriesparallel powertrain, the University of Technology, Sydney plug-in hybrid electric vehicle (UTS PREY); and, a conventional series-parallel hybrid electric vehicle with an internal combustion engine .. The UTS PREY requires only a single electric machine to function as an electric motor or generator in different time intervals controlled by a special energy management strategy. The UTS PREV uses two energy storage devices, the battery and the ultracapacitor, which can work together effectively to maintain the state of charge …
A Novel Anti-Collision Protocol For Energy Efficient Identification And Monitoring In Rfid-Enhanced Wsns, Kwan-Wu Chin, Dheeraj Klair
A Novel Anti-Collision Protocol For Energy Efficient Identification And Monitoring In Rfid-Enhanced Wsns, Kwan-Wu Chin, Dheeraj Klair
Associate Professor Kwan-Wu Chin
This paper presents a dynamic framed slotted Aloha (DFSA) protocol that is energy efficient, and more importantly, is the first protocol capable of monitoring tags. Our protocol uses three separate frames: 1) reservation, 2) body, and 3) monitor. The reservation and body frame are used to identify tags, whereas the monitor frame is used to keep track of identified tags. We have performed extensive simulation studies on all three frames, and compared our protocol with existing framed Aloha protocols. From our results, we confirm that our protocol is suitable for use in RFID-enhanced Wireless Sensor Networks (WSNs).
