摘要：

This study proposes a novel combined cooling, heating and power (CCHP) system with compressed air energy storage (CAES). By storing or releasing the electricity using CAES, the performance of this proposed system is improved, solving the low efficiency problem of gas turbine due to the off-design working condition. Meanwhile, with the energy storage of heat and cold, the proposed system can work with high efficiency under the condition of meeting the users' energy demand. The system is optimized to minimize the fuel consumption and maximize the exergy efficiency subject to the energy demand. Its thermodynamic performance and the effects of its key parameters are evaluated. As a result, the gas turbine (GT) power of the new system is 30.4% smaller than that of the conventional CCHP, with the fuel energy saving ratio (FESR) as high as 29.4%. This study provides a significantly alternative option for the cogeneration system by combining the CAES into conventional CCHP system. Copyright (c) 2015 John Wiley & Sons, Ltd.
