In a photovoltaic system, sun light energy is converted to electricity. The generatedelectricity has a low DC voltage. In order to increase voltage generated by photovoltaic cells (PV),an additive DC-DC converter is required to raise the low voltage to a good level which provides theconditions for connection to DC-DC converters. Low wastes, low costs, and high efficiency are someother specifica...
The US Department of Energy is funding the world’s first cold dielectric superconducting power cable demonstration project at transmission level voltage, to be installed at the Long Island Power Authority (LIPA) grid in 2007. The cable is designed to carry 574 MVA at a voltage of 138 kV. It will remain installed as a permanent part of the LIPA grid. The project team is comprised of American Sup...
Static voltage stability is considered as one of the main issues for primary identification before voltage collapsing in distribution systems. Although, the optimum siting of distributed generation resources in distribution electricity network can play a significant role in voltage stability improving and losses reduction, the high penetration level of them can lead to reduction in the improvem...
In this study the autoregressive distributed lag model and error correction model to estimate Hazard function is used during the years 1377-1394. The results show that in the short term and long term there is substitution between electricity and natural gas in the domestic sector. But the price elasticity of demand relative to the price of electricity is less than 5.0, this result indicates tha...
