Shiraz University Iranian Journal of Science and Technology Transactions of Electrical Engineering 2228-6179 34 3 2010 06 26 Generation expansion planning for Iran power grid 325 333 826 10.22099/ijste.2010.826 EN Journal Article 2009 09 03 Generation expansion planning is one of the major modules of power system planning studies, normally performed for the next 10-30 years. Optimal generation expansion planning is a non-linear and limited optimization problem. All solutions are compared to each other in order to reach final optimal solution. Some simplifications are made to reduce the problem dimensions which will not lead to unreal results. In this paper, WASP software package, one of the well known power expansion planning softwares, is used to optimizeIrangeneration expansion planning. For modeling the power system, WASP uses the probabilistic simulation, while for optimization the dynamic programming method is used. In this paper, the generation system expansion planning is performed from 2009 till 2024 (a duration of 16 years). Finally, the sensitivity analysis is performed on the capital cost and the fuel cost of power plants.            https://ijste.shirazu.ac.ir/article_826_a78da5685241e133233f421f65d48135.pdf
