This study was conducted to investigate the overall efficiency of production and transmission of electricity. For this purpose, sixteen areas of production and transmission of electricity industry of Iran were selected as decision-making units. Based on Khalili and Shahmir’s model, a mathematical model was proposed that includes two stages of the production and transmission of electricity. In t...
With the adoption of the General Policy Implementation Law, Article 44 of the Constitution, the power generation sector (state power plants) has been recognized as a transferable activity to the private sector.Previously, the government exercised its sovereignty over the property With the start of the process of transferring ownership of power plants to the private sector, the issue of how to a...
This paper aims to determine the optimum price of electricity during restructuring process. We maximized social welfare function subject to market equilibrium, maximum production capacity of each group of power plants, maximum demand of each consumer type and the potential of electricity export and import. The model was run using 2007 monthly and annual data by means of GAMS optimization softwa...
multistage stochastic programming is a key technology for making decisions over time in an uncertain environment. one of the promising areas in which this technology is implementable, is medium term planning of electricity production and trading where decision makers are typically faced with uncertain parameters (such as future demands and market prices) that can be described by stochastic proc...
The electricity industry that has been administrated with integrated vertical structure worldwide is now undergoing dramatic changes. Electricity industry is converting to a competitive industry in which market powers determine the price of electricity, there for it is important to identify market power. The Electricity Market of Iran and Iran Grid Management Company were established in 2003 an...
In the restructured electricity industry, electricity pooling markets are an oligopoly with strategic producers possessing private information (private production cost function). We focus on pooling markets where aggregate demand is represented by a non-strategic agent. Inelasticity of demand is a main difficulty in electricity markets which can potentially result in market failure and high pri...
Electricity demand varies daily, weekly, and seasonally. The cost and price of electricity to meet the peak demands can be an order of magnitude greater or more than the cost and price of electricity at times of minimum demand. Nuclear systems are capital intensive, with low operating costs relative to those for most other methods used to produce electricity; thus, nuclear energy is most compet...
The processes of transformation of the energy space, namely the impact of alternative energy resources on it, are characterized by changes in the national economy in general and in the energy market in particular. The results of the analysis confirmed the significant dependence of electricity production indicators on renewable sources and such factors as GDP, CO2 emissions, total electricity pr...
The increasing penetration of renewable energy sources, the demand for more energy efficient electricity production and the increase in distributed electricity generation causes a shift in the way electricity is produced and consumed. The downside of these changes in the electricity grid is that network stability and controllability becomes more difficult compared to the old situation. The new ...
This communication presents a first attempt at making a life cycle assessment of prospective electricity production scenarios which were designed in the EnerGEO project. We start by a basic review of system (in this case, scenario) modelling expectations in today’s LCA study. We then review some of the challenges of implementation due to the lack of detailed description of present and future el...
