Global warming, environmental pollution, fossil resources reduction, the increased demand and price of energy carriers, and various international social and political consequences are among the problems of traditional energy generation and distribution system. In the traditional generation systems, about two-thirds of energy is wasted and the presence of scattered energy resources such as photo...
This paper presents application of an improved Harmony Search (HS) technique and Charged System Search algorithm (CSS) to estimate transport energy demand in Iran, based on socio-economic indicators. The models are developed in two forms (exponential and linear) and applied to forecast transport energy demand in Iran. These models are developed to estimate the future energy demands based on pop...
Examining the factors affecting changes in energy demand can help economic policymakers to adopt energy saving approaches. One method of examining these factors is factor analysis of energy demand. Given the high share of industry, especially energy-intensive industries in Iran's energy consumption, the purpose of this article is to analyse the factors affecting changes in energy consumption in...
E nergy consumption has increased significantly in Iran during the recent decades. In this study, an inter-industrial model has been improved to investigate the sources of the changes in the energy consumption of the country. The input-output tables of Iran for the years 1988 and 2001 have been employed as the database of the model. The innovation of this research allows the researchers to stud...
Population growth and industrial development cause the growth in electricity demand. Supply of this energy needs investment for installation of new power stations and more fuel consumption with different consequences. Furthermore, Demand side management is an approach to rationalize and reduce the rate of demand growth. With attention to the cause and effect nature in energy sector, interaction...
Real-time pricing schemes make the customers to feel the energy price volatility and improve their load profiles. However, these schemes have no significant effect on demand-side uncertainty reduction. In this paper, considering smart grid infrastructures and smart building Energy Management System (EMS), a new real-time pricing scheme is presented to reduce the uncertainty of demand-side. In t...
Industrial energy demand analysis has always been one of the leading fields of research in economics. This issue is more critical in the case of developing countries especially those with transition experiences. In this paper, third generation of dynamic factor demand models for the Iranian manufacturing industries is estimated to analyze the speed of adjustment in factor demands. Data which is...
one of the most important issues about production structure and measurement of factors utilization in industry is the study of substitutability among the production factors. while, energy, for its particular features like finite and the direct relationship between energy usage and air pollution; and specifically abundance of energy resources and allocation of subsidies to different energy carri...
