  7. Abstract:
  8. Energy industries in many countries have initiated the process of privatization. Restructuring of energy systems is usually started with dividing the vertically integrated national systems into regional companies. Due to the geographical dimension of energy systems and natural monopoly in many activities, the process of privatization has started with segmentation of the vertically integrated national systems into regional companies. Thus, regional independent companies are formed that include a collection of producers and consumers of energy in their geographic area. These regional companies are economic entities who are pursuing a policy of maximize profit. On the other hand, exchange of energy among the regional companies is required in order to meet the energy demand in each region. Analysis of multi-dimensional interactions of these companies especially in long-term is a complex task that necessitates development of analytical tools. This thesis has focused on the problem of energy system expansion planning in the restructured environment. Thus, a new energy supply model based on Carnout equilibrium is presented which could help to analyze long-term expansion planning after restructuring. The formulation of the model in a competitive environment is changed from traditional cost-minimization program to several profit-maximization programs with regional and inter-regional constraints, which leads to an LCP formulation and it can be solved by the well known Lemke’s algorithm. A case study based on the electricity-supply system of Iran is then used to analyze the perspective of generation technologies in a 20-year time horizon. Analysis of the results in comparison with the traditional models shows that changes in the structure of electricity supply system of Iran provide more opportunities for innovative and renewable technologies in the electricity market.
