In this paper the factors having influence on travel demand to Iran are paper explored. The hypothesis of the research specifies the variable of “domestic upheavals and insecurity” as the most significant obstacle to expansion of the demand for travel to Iran. To test the above hypothesis, first several demand models that have been proposed to study demand for tourism in different countries, ar...

ABARE project 1653 Natural gas demand forecasts are used by regulatory bodies when setting transmission and distribution tariffs. Reviews of current forecasting methodology used by gas companies indicate that the current approaches may be inappropriate for forecasting gas demand. The modeling methodology for gas demand forecasting and the implications of the results for the regulation of transm...

This study describes the simulation of gas demand for greenhouses in the agricultural area. Using the data provided by an energy company providing gas to over 3600 individual greenhouses , several models are developed to predict the gas demand of an individual green house. Using these models peak smoothing strategies for the overall gas demand can be developed and tested. Three of such peak smo...

1639 Venkateswara and Kumar Firefly Algorithm based Optimal Power Flow with Static VAR Compensator for Improvement of Power System Security under Network Contingency  Abstract— At present owing to the increase in power demand power system have become more complex and heavily loaded, and are subjected to unstable or insecure operations. In order to provide a secure operation of the power system...

I srael is very much an “island” in terms of electricity supply. For political reasons, its grid is not connected with those of its neighbors. Until recently, it had little in the way of domestic deposits of fossil fuels to generate electricity. Th us, Israel relies on imported coal as the primary fuel for base-load electric-power generation: In 2007, coal was used to generate about 70 percent ...

Nowadays one of the most important energy sources is natural gas. By depletion of oil reservoirs in the world, natural gas will emerge as the future energy source for human life. One of the major concerns of gas suppliers is being able to supply this source of energy the entire year. This concern intensifies during more consuming seasons of the year when the demand for natural gas increases, r...

This paper describes a new method for the evaluation of non-utility generation impacts on preventive-corrective control of power systems. The proposed method relies on a mixed integer nonlinear optimization and is capable of recognizing the effectiveness of demand side preventive-corrective actions. A number of cases are presented to illustrate the consequences of introducing demand side action...

The possibilities of balancing gas supply and demand with a green gas supply chain were analyzed. The considered supply chain is based on co-digestion of cow manure and maize, the produced biogas is upgraded to (Dutch) natural gas standards. The applicability of modeling yearly gas demand data in a geographical region by Fourier analysis was investigated. For a sine shape gas demand, three scen...

This paper proposes a novel On Demand Ant based security alert routing Algorithm (ODASARA) for mobile adhoc networks in grid environment, which combines the on-demand routing capability of Ad Hoc On-Demand Distance Vector (AODV) routing protocol with a Ant Colony Optimization mechanism using ant like mobile agents. AODV requires the actual communication to be delayed until the route is determin...
