Abstract：Taking the advanced adiabatic compressed air energy storage system with an energy storage power of 350 MW as the research object,the cost and comprehensive economic benefits of the energy storage power station are systematically analyzed.Thermodynamic and economic models are established to analyze the cost,dynamic benefits and static benefits,and the influence of factors such as purchase price,sale price and equipment price on the comprehensive benefits is explored.The results show that reducing the costs of materials,infrastructure and gas storage rooms by 10%will increase the comprehensive benefits by 47.122 9 million yuan.The price of compressors dropped by 10%,increasing benefits by 38 428 200 yuan.For every 0.1 yuan increase in the electricity purchase price per kWh,the comprehensive benefit decreases by 22.75 million yuan.For every 0.1 yuan increase in the electricity sales price per kWh,the comprehensive benefit increases by 16.582 7 million yuan.
