A hybrid compressed air energy storage (CAES) and wind turbine system has potential to reduce power output fluctuation compared with a stand-alone wind turbine. Dynamic behaviour of such a hybrid system is critical to its operation and control. In this paper, we propose a dynamic modeling approach to a hybrid CAES-wind turbine system. Differential algebraic equation based dynamic sub-models are developed for key components, including compressors, internal heat exchangers, a storage chamber and turbines. A case study is presented where a 2 MW wind turbine is integrated with a small-scale CAES system. Dynamic simulation results show that the power output fluctuation of such a hybrid system can be reduced by 38%, and its stable operation period can be extended by three hours. (C) 2018 Elsevier Ltd.
