the use of renewable energy in power generation and sudden changes in load and fault in power transmission lines may cause a voltage drop in the system and challenge the reliability of the system. one way to compensate the changing nature of renewable energies in the short term without the need to disconnect loads or turn on other plants, is the use of renewable energy storage. the use of ener...
some researches made in the field of agency problem issue, deal with the role of control systems regarding owners and managers. in this research the relationship between the two control mechanisms, namely the voluntary disclosure (external control mechanism) and outside directors (internal control mechanism), which are reductive of agency problems, has been studied. for this reason, a sample ...
هدف از این مطالعه بررسی ارتباط بین مصرف انرژی و رشد اقتصادی در کشورهای عضو اوپک طی دوره زمانی 2009-1995 می باشد. در این مطالعه برای بررسی ارتباط کوتاه مدت از الگوی خودرگرسیون برداری و برای رابطه بلند مدت از آزمون هم جمعی یوهانسن و الگوی تصحیح خطای برداری استفاده شده است. نتایج به دست آمده نشان دهنده آن است که در کوتاه مدت مصرف انرژی با رشد اقتصادی در کشورهای عضو اوپک رابطه مثبت و البته غیر معنا...
considerable consequence of households’ consumption expenditure changes is on energy using in agricultural sector and in other economical sectors. the main objective of this paper was to study of consequences increasing rural and urban households expenditures on changing of energy using in agricultural sector and on producing of environmental pollutants in khorasan razavi province. for this pur...
energy is considered as an important input for agricultural products. a decrease in energy subsidy and its demand reduces agricultural outputs and raises the production costs. changes in production and costs may significantly affect welfare of the agricultural producers. the main objective of this study was to analyze the impact of increased energy prices (reduction in the subsidy) on the agric...
Emissions of more than three-quarters of greenhouse gases by the energy sector have affected climate change in various economic, political and social sectors. Climate change is affecting energy consumption, including natural gas. This article deals with the future of natural gas consumption in the country with regard to climate change until 2030 using a combined approach of econometrics and sce...
abstract according to increase in electricity consumption in one hand and power systemsreliability importance in another , fault location detection techniqueshave beenrecentlytaken to consideration. an algorithm based on collected data from both transmission line endsproposed in this thesis. in order to reducecapacitance effects of transmission line, distributed parametersof transmission line...
In this study, we designed and simulated a system dynamic model to analyze the impacts of energy intensity changes on environmental and economic indicators in Iran. Results show that if the current situation is continued, the industrial sector energy intensity will increase from 2.67 in the base year to 2.704 at the end of planning horizon. So, the sector will consume 540 million oil barrels t...
