In this paper we propose a model for coordinated planning of power and natural gas systems, as a part of electricity supply chain. This model takes into account costs and constraints of both systems, and with hiring simplifications and linearization methods transforms initially nonlinear formulation to a mixed integer linear programming (MILP) problem. Natural gas would be assumed steady state,...

This paper aims to model total electricity demand (incremental) in order to estimate price and income elasticities using provincial data and the spatial panel data method. Electricity demand at the province level is influenced by climatic zones, which can be divided into temperate, cold and sub-tropical. This paper uses time series data for electricity demand in Iran’s 28 provinces, taking into...

Several states and countries have adopted targets for deep reductions in greenhouse gas emissions by 2050, but there has been little physically realistic modeling of the energy and economic transformations required. We analyzed the infrastructure and technology path required to meet California's goal of an 80% reduction below 1990 levels, using detailed modeling of infrastructure stocks, resour...

Approximately 2.4 million tons of bagasse are produced each year in Iran, most of which are currently treated as waste adding to serious environmental concerns. Application of bagasse for energy production is a sustainable solution to supply the required energy within the sugar refineries and export the surplus electricity to the grid. Currently, the energy demand in Iranian sugar mills is main...

Biomass can help reduce greenhouse gas (GHG) emissions by displacing petroleum in the transportation sector, by displacing fossil-based electricity, and by sequestering atmospheric carbon. Which use mitigates the most emissions depends on market and regulatory contexts outside the scope of attributional life cycle assessments. We show that bioelectricity's advantage over liquid biofuels depends...

a r t i c l e i n f o Australian urban transport industries experienced substantial reform during the 1990s leading to significant structural change. Urban transport is typically an important expenditure item for households and structural change in these services may affect households differently depending on their position in the distribution of income and expenditure. We estimate the effects ...

بر اساس قانون عرضه و تقاضا افزایش عرضه هر کالا به کاهش قیمت آن منجر میشود گاز طبیعی هم بعنوان یک کالای مهم و پر مصرف از این قاعده مستثنی نیست و فروش بی رویه گاز از طرف کشورهای دارنده آن در آسیای مرکزی و قفقاز میتواند منافع ملی ایران و روسیه را تحت الشعاع قرار دهد . این رساله فرصت ها و تهدید های ایران را در این زمینه مورد مطالعه قرار میدهد.

Germany has set ambitious targets to transform its energy system from being based on fossil fuels and nuclear to renewable energies, requiring electricity grids to be upgraded. As a result there is significant public pressure in some German cities to exert greater local control over electricity distribution infrastructure. A case study approach was used to investigate contestations around owner...
