The Impact of Wind Power Generation on Wholesale Electricity Price at Peak Time Demand in Korea

Seunghyun Ryu, Shinyoung Um, and Suduk Kim Abstract In this paper, wind power is analyzed to see its impact on wholesale electricity price or SMP System Marginal Price at peak time under the consideration of the stochastic characteristics of its power generation. For this purpose, future power supply curve is estimated considering future fuel price for power and the construction and decommission of power plant's plan. Future oil price is assumed to follow EIA's future oil price scenario and the...

Tidal Turbine and Result

Figure 3 shows that the tidal turbine individually simulation output using PSCAD EMTDC. The tidal turbine models were modified from wind turbine IEEE models available in the PSCAD master library 3 . It shows the real power P WMW and mechanical torque Tmtidalpu of the turbine, also with the tidal AC voltage line to line V RMS kV . The design parameters of the tidal turbines are listed in Table 2. Figure 3 shows that the tidal turbine individually simulation output using PSCAD EMTDC. The tidal...

Transmission Line System

Figure 4 shows that the AC power generated by the wind and tidal turbine generator are converted once into DC power with the rectifier and transmitted onto land via an underwater power cable. It is converted again into AC power through the inverter. The hybrid DC link unit is used to convert the output AC-DC-AC through a 6-pulse GTO converter and inverter 4 . Figure 5 shows the hybrid turbine simulation output using PSCAD EMTDC, from top to bottom, the converter DC current ICON-DCpu and...

Ferric Oxide Carbon Composite Synthesized by Aqueous Solution Method as a Cathode for Lithium Ion Batteries

Jcpds 1346

Abstract Iron oxide is one of the most promising materials as an electrode of lithium-ion batteries due to its low toxicity and low cost. In this study, composites of nano-sized g-ferric oxide y-Fe2O3 and carbon material is synthesized by aqueous solution method, which is generally conducted at low cost. Acetylene black AB or ketjen black KB is adopted for the carbon component in the composite. These composites y-Fe2O3 AB and y-Fe2O3 KB are examined as cathodes of lithium-ion batteries and they...

Renaissance of Nuclear Energy in the USA Opportunities Challenges and Future Research Needs

White Queen Quotes

Abstract The future of nuclear energy is an important issue for many countries intending to reduce their dependence on fossil fuels and achieve the reduction targets for green house gas GHG emissions. As of June, 2008, there were 439 operating nuclear reactors with a total generating capacity of 372 GWe and 42 power reactors under construction in 15 countries. In the USA, a total of 104 nuclear reactors currently produce 20 of the electricity and account for at least 70 of all GHG-free...

Results and Discussion

Marine Pollution 2011 Simple Bar Graphs

RNP receptors for dopamine were isolated from an RNP library by in vitro selection method as previously reported 3, 5 . In each round of selection, an RNP pool was incubated with a dopamine-immobilized agarose resin. After removal of unbound RNP fraction, a bound RNP fraction were recovered by specific elution with free dopamine. An ethanolamine-agarose resin was utilized in the negative selection step of dopamine, respectively. The bound RNA fractions were collected, reverse transcribed and...

Raman Spectroscopy of SiClTmhatfsa Electrolytes

Raman Spectra

First of all, the dissolved state of silicon chloride species in TMHATFSA was investigated by Raman spectroscopy. Figure 1 summarizes the results of peak separation for the vx symmetric stretch mode of SiCl4. It exhibits almost no influence of TMHATFSA on the peak position and width for the vx mode of SiCl4 in the electrolyte solutions. It means that silicon chloride species exists mainly as SiCl4 molecules in TMHATFSA without making bonds with other molecules to form complexes, polymers, or...
