  7. Abstract:
  8. The role of natural gas compressor stations, is to maintain the gas pressure at the level required for gas transportation along the pipeline to the distribution system. In Iran, residential heating demand, has a large share in natural gas consumption. Thus the demand of natural gas would be greater in cold winter days in comparison to other seasons. Due to this intense demand fluctuations, geographical diversity of demand, long distances between supply and demand points, supply and demand mismatches and long term investment, there is an intense reliability and load factor issues within these systems operations. In this thesis, natural gas compressor stations are modeled and installation and operation of these systems are economically optimized. To achieve this purpose, the components of natural gas compressor stations are modeled as linear functions and optimized through a MIP Solution, thus availability of the system added to optimization algorithm, as an exponential constraint iwthin a genetic algorithm. Optimization solution replies that increasing redundant compressors has greater impact on compressor station availability. also increasing in compression demand factor lead to decrease in compression average costs. and combine generation of compression power and electricity would enhance gas turbines load factor and lead to decrease the avegare costs of compression and cost of increasing availability
