| 英文摘要 |
| Compressed air energy storage is a new physical energy storage technology, its thermal cost reduction and energy
efficiency improvement can be achieved by using model predictive control. In order to realize the temperature control
of the compressed air energy storage system, the thermodynamic characteristics of heat exchanger system, thermal energy
storage system and salt cavern gas storage system in the compressed air energy storage system are analyzed. Based on the
analysis, the lumped parameter and distributed parameter coupled system model of the compressed air energy storage system
is established. Then, the model predictive control strategy is designed for the coupled system. For solving controller’s
complex constrained optimization problems, a discretization method based on Cayley–Tustin transform is proposed to improve
the control accuracy of compressed air energy storage system. The simulation results show that the model predictive
control can avoid the disturbance caused by the weather change, and can effectively improve the heat energy utilization of
compressed air energy storage system. |
