| During recent years, restructuring of energy systems has been triggered as a drastic movement by many countries. Relevant experiences show that pure market mechanism will not ensure long-term demand satisfaction and optimal expansion of the supply system. Therefore, expansion planning of the energy supply system is considered as a fundamental issue in the restructuring studies. Unlike conventional systems, Competitive condition makes planning more complex in new systems. Analysis of recent studies in long-term energy system development shows that the market equilibrium evaluation is an effective and useful technique that is used to analyze the optimum condition of the energy supply system. In this paper, basically a Nash-Cornet Market Equilibrium model has been suggested to predict long-term expansion of the electricity generation system. Conventional version of this technique is very complex due to high span of existing dataset and variables, so one may not find a clear solution to solve it. Thus, to find an approximate solution for the suggested model, an algorithm based a combination of static and dynamic equilibrium planning methods has been established. Discounted net profit has been considered as a goal function for each generation company to be maximized during the long-term horizon. Implementation of the algorithm and its case study results over a hypothetical power generation system are presented. |
