Abstract: Wind speed varies randomly over a wide range, causing the output wind power to fluctuate in large amplitude. An adiabatic compressed air energy storage (A-CAES) system with variable configuration (VC-ACAES) is proposed to cope with the significant power fluctuations of wind farm. It broadens the operational range of A-CAES system by allowing multistage compressor and multistage expander to operate under variable modes. Off-design modelling of the VC-ACAES system is constructed. Based on the characteristics of a real wind farm rated at 49.5 MW in China, a matching VC-ACAES system is designed. With variable configuration, it is possible to increase operational ranges of compressor and expander of the proposed system by 70.85% and 27.27% respectively. VC-ACAES system performance when integrated with wind plant is investigated and analysed. Results indicate that after integration with the VC-ACAES system, wind power (average: 21.05 MW) with fluctuations up to 49.5 MW can be stabilized to a steady electric power of 18.64 MW, and wind power utilization coefficient is increased from 26.29% to 71.02%.
