Power and
Energy (PE)
Society The Power and Energy Society (PE-31) is involved in the planning, research, development, construction, installation, and operation of equipment and systems for the safe, reliable, and economic generation, transmission, distribution, measurement, and control of electric energy. The Power & Energy Society provides a forum for sharing the latest in technological developments in the electric power industry, for developing standards that guide the development and construction of equipment and systems, and for educating members of the industry and the general public.

This presentation discusses the integrated process successfully utilized at numerous fossil fueled generating assets around the world over the past ten years. Results obtained from implementing recommendations are shared for units in both regulated and unregulated markets. Also discussed are products developed specifically for quick implementation in the areas of efficiency, flexibility, and reliability.
In 2003, a widespread blackout affected 50 million people in eight U.S. states and two Canadian provinces. The following year, the U.S. Department of Energy, Office of Electric Transmission and Distribution, formed a group of stakeholders in the electric industry to design "GRID 2030." The aim of this workshop was to develop a road map that represented the critical GRID architecture, accelerate technology acceptance, strengthen the electrical market, and develop private/public partnerships. This lecture also discusses the collaboration of private and public organizations, including those integrating renewable energies with commercial-off-the-shelf technologies.
Strategies are covered to minimize the carbon footprint in fuel production by maximizing carbon conversion from biomass.
This lecture covers efficient automation of the power distribution system, and reviewes a case study of electric power distribution systems. Alternative system designs are also reviewed.
Existing LI wind-power projects and plans for future projects, such as the one off the coast of Jones beech, are discussed. Site screening, avian avoidance, grid interconnections and numerous other installation considerations are explained. Also covered are the environmental benefits, aesthetics and costs.
The next great economic era will be powered by hydrogen pointed out Mr. Rifkin, the president of the Foundation on Economic Trends. Drawing on a variety of well-balanced research studies, his basic premise is that the world must switch from a fossil-fuel economy to a hydrogen economy. This must happen soon for three reasons: the imminent peak of global oil production, the increased concentration of remaining oil reserves in the Middle East one of the most politically and socially unstable regions of the world and the steady heating up of the world's atmosphere from fossil-fuel dependency. The Center for Fuel Cell Development at the Institute for Research and Technology Transfer (IRTT) of Farmingdale State University of New York has successfully developed new metal treated bipolar plates for PEM fuel cell power stacks. These power stacks are much safer, very robust and more economical than the graphite bipolar plates that are currently being developed nationwide. The metal bipolar plates provide at least a 12% savings in hydrogen consumption in comparison to graphite because of the lower ohmic resistance of metal.
Today, 21% of energy use is in lighting, and, perhaps, half of this energy or more can be saved by switching to efficient and cold solid-state lighting sources. Solid-state lighting will use visible and UV LEDs that are projected to reach lifetimes exceeding 100,000 hours. From traffic lights to road signs, from automobile taillights to outdoor displays, from landscape to accent lights, solid-state light sources have already arrived as harbingers of the next lighting revolution. However, the creation of appropriate sources of white light is the ultimate goal of the solid-state lighting technology. The efficiency of white LEDs using conversion of blue or UV light in ionic phosphors (now approximately up to 20 lm/W, already twice of that for incandescent lamps) is expected to reach 50 lm/W by year 2010. Polychromatic all-semiconductor lamps based on state-of-the-art red-to-yellow AlGaInP LEDs and blue-green AlInGaN LEDs with the quantum efficiencies in excess of 50% and 20%, respectively, can exhibit luminous efficiencies exceeding 100 lm/W and compete with any conventional white lamp. Optimization of such multi color LED modules is one of the most important problems of the emerging solid-state lighting technology. A dichromatic LED lamp can only provide a high efficacy with general Color Rendering Index close to zero. Trichromatic and quadrichromatic lamps are able to cover the entire range of reasonable general CRI values. |
