Abstract: Due to the lack of effective utilization and recovery processes, most of the low concentration coalbed methane in the mining area is directly drained, resulting in serious resource waste and greenhouse effect. At the same time, with the increase of the penetration rate of renewable energy which is intermittent, random and fluctuant, the safe and economic operation of the power system is facing severe challenges. The advantages of low concentration coalbed methane resources in the mining area and compressed air energy storage are combined in this paper, and a structure of complex integrated energy system for mining with coalbed methane and compressed air energy storage is proposed. The waste gas resources with residual pressure in the purification process are recovered and used as intake source for compressed air energy storage. The underground abandoned mine tunnels are used as compressed air storage and coalbed methane storage respectively, forming a residual pressure utilization compressed air energy storage. In this paper, the compressed heat in the energy storage and the residual heat generated by power generation are fully utilized, so that the renewables are complemented and adjusted through the combination of heat, electricity and storage in the mining area. Based on the proposed structure of the mining area, the system model is established, and then a multi-objective operation model is established with the system operation cost, wind power consumption and carbon emissions as the objectives. The integrated energy systems of the mining area with or without pressure swing adsorption are compared by example analysis, and the results show that the complex integrated energy systems for mining exhibit good economy, wind power consumption and carbon reduction ability.
